3D printed loupe for BMPCC 4k and 6k

PostSat Sep 21, 2019 9:30 am

This is the first version of the 3D printed loupe for BMPCC 4k and should also fit 6k (but not tested yet)



The STL files are here: https://drive.google.com/drive/folders/ ... sp=sharing

We are currently printing first units for few already selected testers. In addition we will provide DIY kit for 3 first person posting picture of the 3D printed parts on this thread. (one kit per person)

The DIY kit includes lens, magnets and screws needed for the build.

This is a do it your self build and provided as it is. If you decide to build it you do that at your own risk. you may use the provided STL files for your personal use and even print for a friend. They may not be reverse engineered or modified or in any way used commercially without agreeing first with us.

The DIY kit will be available at start of October.

Reserved for instructions

The BMPCC 4k and 6k Loupe Version 1 files are at

https://drive.google.com/drive/folders/ ... sp=sharing

Print all these files. If you want shorter eye cup, or two colour sun cover, see the folder optional.

If you are experienced in 3D printing just ignore the following or provide your suggestions, they are very welcome. This is just to support those who are not that experienced on 3D printing yet.

I am sure you will be after you realise how useful it is for camera gear. :D

We use the Original Prusa i3 MK3S 3D printer and their PET filament https://shop.prusa3d.com/en/23-pet with very good results. If you have different printer, and want to use PLA, ABS etc. that is totally fine. We use the PET as it does not smell when printing and it hold its shape well even in hot sun. PLA may loose its shape on hot. As I understand the PET is basically same material of witch plastic bottles are made, so it should be pretty safe (but no guarantee on that, I suggest you study the materials you use.).

This is suggested orientation for the peaces. On this one support is added everywhere, just use the add support everywhere option on your slicer SW.

Note: The Eycup should print fine also without support.

For printig quality I suggest 0.20 mm and 15% infill. With theses settings the print takes about 23 hours with the Prusa printer we have. This may wary between printers. You could use also different printing resolution but I suggest printing everything on same quality, so they should fit better together.

After printing remove the support materials, you could now test it just assembling the eye cup, and after continue attaching the magnets to the sun cover and T5 holder. I will update the instructions for this part later on.

Remember though the sun cover is important to have and close when the loupe is not used. Otherwise sun could burn your screen or worse, the class element is a magnifying class.

The DIY kit is 50 euro + shipping (VAT 0%), contact me if you want one. Shipping is via mail in Europe around 15 euro, must verify other destinations. If you buy as private's person inside Europe, we need to add 24 % VAT.

To order contact me, and I will provide invoice. Payment is before shipping, via PayPal or bank transfer.

Currently the DIY kits are out of stock, estimated to be available 24th February.

Just received Cineroid Soft eyecup covers. The current eyecup was not specially designed for these but fits pretty nicely. Will maybe adjust slightly to make better fit, make an eye cushion version of the eyecup

Where possible, I would use a matte finish plastic or cover the inside with flocking. Flocking would be best.

There was some worries of them looking very heavy, however that is not the case at all.

They are very solid, but as they have been printed hollow with support material, they are mostly air inside. That is one of the strengths of 3D printing, being able to do structures that would otherwise be very difficult or impossible.

Ps. for those who are printing these we have used 15% infill except the T5 holder that is printed solid, so that it is more flexible and strong, it is a small part anyway. The material we used is PETG. It prints nicely it can take direct sunshine better than PLA. PETG is basically the same materia plastic bottles are made of.

If you are interested send me email (found in here http://levitezer.com/styled/)

We are looking visibility for this project. I will select the one to get it at next Monday morning Finnish time.

Many have asked directly to buy this, we are not much interested to manufacture these by our selfs. The idea is we provide the DIY kit (lens, screws, magnets) and the printable files. https://drive.google.com/drive/folders/ ... sp=sharing

The DIY self kit is not much business for us, but we will have that available 50 euro + 10 euro shipping by normal post. Note, the 3 first ones that post pictures here of their 3D printed loupe gets the DIY kit for free.

If someone really wants to buy the loupe directly from us, it is 180 euro + 80 to 120 euro shipping by DHL

Hi Kim,

I'm Diego from Barcelona. First of all thanks for sharing the 3d printable files!!

Normally I use my pocket hand held under sunny conditions and the camera screen is not bright enough. At least in may case, it also is extremely difficult for me to see the focus assist. So I decided to try your design in print the parts and here they are:

The loupe fits really well to the camera body and looks amazing!!!

I do not know If there are still one of the 3 DIY free kits available.

Thanks and Regards,
Diego

The DIY kit is on the way for Diego, 2 more free kits available to who post first here the 3D printed parts.

The kit includes the lens, 3 magnets for the sun cover and loupe and 3 screws to attach them, the set screws are for the sun cover hinge.


The 3 smaller magnets are for the T5 attachment and the 1/4" screw is obvious, to attach it to the camera and of course the LeViteZer sticker, two of them.

The smaller magnets need to be glued (glue not included). Just but a small amount glue on the magnet side, not bottom. The polarity of the magnets is important. They are placed on the loupe so that the oposite poles point out. To the adapter it is attached so that the lower loupe magnet attracts the magnet on the T5 adapter and so the upper magnet repel it. The adapter magnet in my hand on this video.



The lens is packed like this. The black tape is just to protect the lens, but the narrow very thin brown tape is needed, so please do not cut. It is Kapton tape, to put around the end of the loupe under the eye cup. It makes it to rotate smoothly and easier to attach/remove. Instal first the sun cover.

To attach/remove the eye cup first rotate it on this position.

The eye cup on the picture has longer sleeve, to provide a bit different diopter adjustment also it has a bit looser attachment to the loupe than the original for easier removal.

EDIT: I obviously was not very well focused yesterday, there should be 3 attachment screws for the sun cover magnets. 3 magnets, 3 screws, so simple and I miss it :oops:

Screw the set screws in so that they hold the sun cover and adjust so that it moves freely.

The new eye cups added to https://drive.google.com/open?id=1ZyfEZ ... 2XItix34ur

- eye cup 5 long.stl (longer version)
- Eye cup 5 long adapter.stl (needed with the above)
- eye cup 5 short.stl (same as previous eye cup version 4, but looser fit, good with the KAPTON tape.)
- eye cup 5 short.stl (to be used with the long and short version 5 eye cup)

Thanks very much to Kim for sending me an "unfinished" 3D printed LeViteZer loupe body and parts kit for the Pocket 4K & 6K cameras!

I cleaned-up the printed plastic parts (there were a few rough edges which required a little filing) and followed Kim's instructions to assemble the loupe. The completed loupe works really well!
IMG_6665-1080.jpg
IMG_6665-1080.jpg (173.93 KiB) Viewed 10871 times

Here's an iPhone 6 photo of the inside of the loupe taken through the loupe's eyepiece glass lens, after I painted the interior of the loupe with flat black spray paint:
IMG_6704-after.jpg
IMG_6704-after.jpg (398.96 KiB) Viewed 10583 times

Pros:
- Less-expensive compared to most external monitors & EVFs.
- The loupe's glass lens provided by Kim produces a sharp view of my Pocket 4K cam's monitor. With the monitor set at 50% brightness I have absolutely no problem seeing the screen, even in bright outdoor sunlight. Critical focussing is a breeze. At 50% brightness (instead of 100%) the cam's battery should last a bit longer, too.
- Compared to using a monitor, a loupe (or EVF) helps steady handheld shots by providing an additional point of contact (your head). IMHO, the view thru a loupe or EVF is more immersive compared to looking at a bare monitor because there are no visible distractions surrounding the screen -- so it's easier to pay attention to small details within the frame. Makes a big difference!
- The loupe is lightweight but seems very sturdy. Compared to an external monitor or EVF, the loupe is lightweight, doesn't require power or cables, and of course can't cause wear & tear on the cam's HDMI port.
- Loupe has a large opening on its bottom side which allows for very easy access to the touchscreen. It's a little weird watching the silhouette of your "giant" finger reaching in to use the touchscreen! :-)
- The built-in flip-up screen-protecting sun cover mechanism works great! The sun cover prevents direct sunlight from being magnified by the loupe's lens and damaging the cam's monitor. The loupe's sun cover mechanism is clever & effective.
- The loupe protects the cam's monitor from bumps, scratches, etc.
- Kim's design includes a bracket to hold an external T5 SSD, but I haven't tested this yet.

Cons:
- Unlike an external monitor or EVF, a loupe doesn't articulate. So a loupe may be poorly-suited for low-angle and other awkward shots.
- The loupe adds about 6" to the camera's overall length. IMHO this isn't a major problem considering the loupe's benefits.
- The standard design of Kim's loupe is intended for use with a "bare" Pocket 4K/6K cam. As-is, it doesn't mount to a cage. However -- if you know how -- you can edit the 3D files to modify the loupe to make it fit your cage. Or, you can modify the standard 3D printed plastic itself so it mounts on a cage, as I've done for use with a SmallRig cage:

A close-up of the loupe's built-in flip-up screen-protection sun cover mechanism. Note the location of the "large" magnet (silver disk) provided in Kim's parts kit. I secured it with a drop of super-glue (didn't need to use the provided screw). Also note the 2 very small black set screws provided in the kit. Because I didn't have a small-enough tool to install these properly, refer to the photos below for a description of an alternative installation.
IMG_6654-1080.jpg

Instead of using the 2 small black set screws, I used a <2" piece of insulated solid copper wire ...
IMG_6666-1080.jpg
IMG_6666-1080.jpg (244.1 KiB) Viewed 10869 times

... and inserted it into the neck of the loupe -- and through the hinge of the sun cover -- instead of using the set screws. The collar of the lens eyepiece holds the wire securely in place. Works perfectly.

I discovered I only needed to use 2 of the provided magnets (a large one & a small one) to make the sun cover mechanism work. I installed the small magnet like this ...
IMG_6671-1080.jpg
IMG_6671-1080.jpg (193.9 KiB) Viewed 10866 times

... and the large magnet can be seen installed in the sun cover mechanism below. Orient the magnet in the loupe body and the magnet in the sun cover part so they REPELL (push away) each other. Works great.

Note: Kim's instructions are different, using a total of 3 magnets (2 in the sun cover part & 1 in the body). But the way I did it only requires 2 magnets & seems to work fine. See:

Peter, might be a little bit trickier but I think lining the interior with black felt or the matte material used (to prevent reflections between the rear of a lens and a camera sensor) in camera mounts.

As noted above, I modified the 3D printed plastic body of Kim's loupe so I could mount it on my SmallRig full cage. Even after these modifications, by adding a few additional metal washers as spacers the loupe can still be mounted onto a bare cam without a cage.
IMG_6683-1080.jpg

Using a hacksaw I carefully cut the loupe's top bracket, and drilled a hole through it. To reinforce the hole I glued-in a 1/4-20 threaded brass insert:

I also trimmed the loupe's bottom tabs:

I made a small aluminum mounting plate with 2 holes drilled in it. One hole allows the plate to be bolted to the loupe body (into the threaded brass insert) using a 1" long 1/4-20 bolt, and the other hole is for a short 1/4-20 bolt into the top of the cage. The result is very strong & secure.

The modified loupe body can also be mounted to a camera cage using a small magic arm. See:

As noted above, to reduce reflections inside the loupe body I'll spray paint it flat black.

Here's a before & after paint TEST using an spare 3D printed part.

Looking good, how is the paint holding on the plastic? Did you need to add any spacers between the loupe and metal plate, or was it by accident correct height?

It is good thing you trilled trough the T5 adapter. it is printed solid. The loupe it self is very thin plastic with support structure inside. That is one of the strength of 3D printing, being able to make this kind of solid but light structure.

If there is demand, I will make a 3D print that fits different cages, but need the cage to do the fitting, so if Tilta, or Small rig etc. is reading, maybe providing me one ;)

I think this particular paint will work well for the interior surface of the loupe. It’s quite flat (matte). I’m not certain, but I don’t think it would be durable enough to use on the loupe’s outside surface.

The top of the loupe’s T5 clip/bracket is EXACTLY the same height as the top of the SmallRig cage. :-)

A sweet future version of the 3D files could be a 2-piece body: A rectangular frame around the monitor with embedded magnets and bolts to the top & bottom of the bare camera, and the main loupe body which mates to the frame via magnets. Different versions of the frame could be designed to fit specific cages.

Cheers.

Some times you get lucky :D it was not designed to match the small rig height put perfect that it does.

The beauty of 3D printing is that product thinking can be much changed. Things do not need to be modular, it does not need to be designed multi use, you just print exactly what is needed.

Also sending the DIY kit to US cost about 10 euros, and it probably gets easily trough customs due its value 50 euros. Shipping the complete loupe to US is 80 euros just for shipping and due its higher cost it probably causes some additional cost and delay at customs.

The problem with 3D printing today is that it seems to be alien technology still for many and many do not have access to 3D printer. Hopefully in future that will change*

However I have been thinking a structure with hinge so that the loupe could be lifted up and when lifted up pulled sideway to remove (magnets could be used to secure it on place). There could be a sun hood that can be attached similarly. This would make it easy to fast swap the loupe to any 5" display, like Video assist. This would be good justification to fit it with adapter.

Ps. my current integrated sun cover / loupe for VA. It is snap in design, easy to instal and remove.

*We are using ORIGINAL PRUSA I3 MK3S 3D printer. It is simple and has been working very reliably. it cost around 1000 euro, so not exactly cheap, but very reasonable priced I think. Prusa has now also ORIGINAL PRUSA MINI 3D printer that is only 350 euro. I have not tested it yet but if it proves to be anywhere as good as the one we have now, very interesting. Note though the print area size.

The photos below are before & after painting the interior of the loupe body with flat black spray paint, as viewed through the loupe's glass lens. In actual use a noticeable improvement.

Magic arm, quick release, SmallRig cage, and LeViteZer loupe for the win!

I also have a matching QR plate bolted onto the bottom of my 7" external monitor, so it's easy to swap between it and the loupe if required.

If a small lens is mounted on the camera, the magic arm allows the loupe to be positioned so it nests/covers the lens for compact storage in a camera bag.

Blackmagic with a magic arm, what could be better. That is a cool idea. When I find some time, will look into making a version that supports this idea.

Using some spare rig parts, I improvised an offset bracket for my shoulder rig to see if the loupe's eyepiece would line up with my eye. Happy to say that it works great. Very comfortable & stable. The battery sits on my shoulder & helps balance the rig.

I'll probably buy an offset bracket like this one because it'll weigh a few ounces less compared to my solution:

Thanks Alexander for the review.

The comments I have so far collected are:

1. Cage version. The solution Peter proposed above is nice as it does not require tailoring per cage. Tailoring it self is not much work if I would have accurate 3D models of the different cages and the actual cage to test. I will contact Small rig and TILTA if they would be willing to assist.

2. Internal reflections. One solution is to paint as Peter did. I could also make some diffraction pattern inside, it prints just as easily as flat walls.

3. Eye cup to be used with eyeglasses. The current eye cup is already quite large when used without the eye cushion. However we can easily made wider version. The lens it self is 50 mm diameter, so easy to view in. The lens is high quality glass lens.

4. Better instructions how to build it.

These are things I will certainly look into at some point. At this time this is though purely at hobby status, quite expensive and time consuming one. Anyway it means it is low on our priorities, I will look into it hopefully still during this year.

It is good to see there is interest to this, based that this thread has already been viewed over 5000 times.

However we have still the 2 of the original 3 free DIY kits available for next 2 that post pictures of their prints in here, so not really a success so far.

I hope people would find the public 3D printers available in many places. After the parts are printed it is easy, less than 1 hour build. And actually printing the parts is really easy too, those public places usually have someone who will assist you.

I just visited the local library during lunch, I hope such places are available in many places around the world.

The DIY kit is 50 euro + shipping 10 euro VAT0%. To order, just contact me. When hopefully one day there is more demand :D , we will sell it via resellers. As mentioned the two first ones posting pictures of the printed parts, will get it for free.

I get frequent request for the ready build units, well, it takes 20 hours to print, it takes over an hour to assemble and prepare shipping, shipping cost is 80 euro as it is big item. However if someone wants to print and sell it, we are fine with it as long as the DIY kit is bought from us for every unit. Just contact me and we will agree on it.

Yes for the small rig full cage please - The pellets have just arrived and we're about to press the go button. Any idea how long it might take?

I’ve been testing the loupe out for sometime now and it’s been great. I’ve really missed a loupe for the pocket4k camera. The screen is useless without one because of sunlight, but also because the screen is too big to see if you hold it at the distance from your body that you need for stable shots. Hold the screen that close without a diopter and everything is a blur.

I added a padding from an old viewfinder which I liked. Otherwise it's too stiff.

Its great to have a small form factor setup for the camera and I found the build quality fine. I liked that I can reach the touch screen while shooting but it also created some problems because sunlight would reflect in some angles.

Diopter works great which was my main concern.

I did have some issues with the lens fogging up which I don't know is a material thing or how I'm using it. Something to look into.

I like the feature which protects the lens but it is a bit too bulky and fiddly to get to so I'd like a more simple and clean solution to that.

The size is pretty massive, which isn't something you can do anything about because it's a screen size thing, but it's very far from small :D I don't have a problem with that, but if you want small package it might be better with a small evf solution. For me the loupe is more versatile and creates a smaller rig when needed.

One thing I'd love is if the loupe had various mounting options. One for pocket, but also for other screens in similar size like my Shinobi. It would make packing and setting up much easier.

One big thing for me is that I have to have a snap on type of loupe for quick on and off switching. Screwing it become a bit fiddly. But even more so it has to be usable both with and without a cage. Now I found myself dragging to use it because I had to take the cage off to do so. But having shot a two very sensitive docs this summer I would have loved to have the loupe for that, now I either had just the screen to rely on (which sucked), or I had to use a GH5 instead of the pocket4k to get the shots. Having a loupe is perfect for those situations, and I don’t want to get lower quality footage just because of a thing like that.

I think the simple way of having a loupe has great potential and I really want to have one that's universal enough to work with my tilta cage.

Great potential and it's already a really good build, it's just about fine tuning and fixing the mounting to be more flexible so you don't need 5 different things to watch your screen :D

I got this today, the SmallRig cage and magic arm. Will do similar as Peter suggested above first and then likely direct fit to the cage. This will be likely at the start of next year.

The elements for next setup(s) + the loupe missing on the picture.

Setup.jpg

The 5" VA with the magnifier class will be great as a 'viewfinder' just need to set up the wiring, and the cage is great for that. should get a handle to go with that. It will be simple and manageable setup.

I have not used the shoulder rig, I think I would use it with the bare loupe, no cage needed, it is just additional weight.

With Loupe.jpg

The solder rig feels a bit funny being very top heavy, though eye provides good 3rd support point. Any sideways movement causes the camera to roll. To balance it I am planning to put a V-Lock battery below the handle. I think that would do the trick, to stabilise the roll. I am not sure though I would want to go in public place with that kind of rocket launcher :)

We will see, maybe something useful comes out of this.

I find myself missing the electromechanical control for Focus, Aperture, WB, Zoom.... that I had on this rig.

Sure they are on the touch screen, but I do not like the touch screen. Would really prefer a joystick for navigating on the menus and direct control for the above mentioned.

We have BT control for current BMD cameras, but I really prefer the direct electrical interface on the micro cameras, though it was also limited not offering two way serial control. Anyway currently I have no time to make such manual controller.

good idea. Next to the eye/head attach point there needs to be a vertical balance.

I would suggest printing on the orientation as on this video.

We have few more DIY kits available immediately and will order more lenses as needed.

The DIY kit includes
- lens
- magnets
- screws
- the brown transparent kapton tape, to be put between eye cup and loupe, it is around the lens please do not cut. this makes it rotate smoothly.

Some printing guidelines given on second post. Will update the assembly later on on the second post.

Currently the DIY kits are out of stock, estimated to be available 24th February. This does not affect those who have already ordered or with who we are finalising the order.

3D printing it a pretty wonderful thing. it produced objects that could not be otherwise produced, like you can see from these pictures Peter posted above.

Complex infill that makes it strong and very solid, but still pretty much empty inside and light. Is this necessary for the loupe, not really, more clumsy loupe would do the job just fine and could even have some advantages.

However this loupe is designed to be 3D printed, and to be very solid. It is not suitable for other manufacturing methods and 3D printing is not great for mass producing big objects like this. It is great for manufacturing them locally, if one has access to 3D printer.

We will not manufacture them for sales, unless one understands it will look like 3D printed and wants to pay 250 euro for it and 80 euros for shipping, we use DHL. No I do not expect to sell any like this, it is just my way saying we do not want to do it.

The DIY kit is 50 euros (VAT 0%) and shipping between 10 to 20 euros via normal post. The material to print it cost less than 10 euros...

Quite truthfully we do not want to sell low cost items like the DIY kit either, one by one, we do not have resources or web shop to do that. Usually we do business to business, I should have thought it trough before starting this project. It is a fail and tempted to close it down.

The loupe it self, though I say it my self I think is pretty good, and happy to see others are agreeing.



it is just the business side around it that has failed, people are not ready to manufacture locally.

Sorry for the outburst, I will order now 20 lenses more, so we should have the DIY kit available on a week or two.

When you contact me to buy it, please provide:

- Name and shipping address
- company name and VAT ID if you have one.

I will provide an invoice, Payment via PayPal or Bank transfer. Buyer pays all money transfer costs. Shipping after payment.

If you are buying as private person from inside EU, 24% VAT will be added. Outside EU or company with VAT ID is VAT 0%.

Sorry for the inconvenience on the ordering process. If one day there would be more demand we will make it available via resellers for everyones convenience.

I have had the BMPCC 4k for long time BT development purposes and also made the loupe.

However this is really the first video, except some test shots I have made with it. It is all handheld with this setup. As I am editing with solar power and FCPX, shot it ProRes 422 FHD only. :)

When we woke up this morning, there was just nothing around us, just a strange fog, no sun, no clouds, no horizon, no sea no other islands visible just the island we are at. This video was taken when the fog had already gone a bit.



Ps. I have now also a gage for it, but really do not like it. It just makes everything really big. Better battery solution is needed, now it is with internal battery. It is just not sufficient.

A while ago I modified my Levitezer loupe so I could mount it on my SmallRig cage using a magic arm, a very versatile combination perfect for many situations. See:
viewtopic.php?p=561310#p561310

I've now modified an inexpensive steel hinge so I get most of the versatility of the magic arm, but in a smaller, lower-profile, and lighter configuration. Another advantage of the hinge is that it can be quickly raised & lowered with one hand (a magic arm usually requires two hands). Currently the hinge is secured with three 1/4-20 bolts.

I might modify it further so it can mount via a cold shoe, and add a couple of small magnets to "lock" it in its up and down position. But as-is it works really well, especially for shooting while walking around.
