(Rookie Question) Lens with Blackmagic Pocket 4K

PostTue May 26, 2020 5:51 pm

Good afternoon Blackmagic community!

I've just bought my new baby, the Blackmagic Pocket Cinema 4K, very excited to use this!

https://twitter.com/m77oz/status/1265316020878794752

I might've misread but I thought my Canon lens would fit directly in the camera box, unfortunately doesn't seem to be the case. I have a 18-55m Canon, also a Samyang 2.8-14mm, but they don't seem to fit (didn't want to try to much to fit it in lol).

I thought I read it would fit, but it's no problem at all I was actually looking to buy a Sigma 18-35mm but I was wondering what would be my cheaper option at the moment?

What type of Mount Adapter I can buy to fit the type of lenses I was previously mentionning. Do you think it would be worth investing in a SpeedBooster or something cheaper like a Viltrox EFM2?

At this stage I might be best to buy a Sigma 18-35mm, but does that fit directly in the camera box?

Lots of questions, appreciate your help in advance!

Very exciting!

the pocket 6k has an EF mount, but the 4k has MFT
and this is the good one, so you can use a lot of lenses

but you need a converter MFT > EF

the best you can buy is the metabones BMPCC 4K MFT to EF speedbooster

there are any cheaper, but the quality of metabones is unmatched

Gotcha so even if I want to buy the Sigma 18-35mm I would need the Speed Booster anyway? What lenses would fit directly in the 4K out of curiosity?

I was already looking at buying the Metabone SpeedBooster.

So I guess the next step is Metabone SpeedBooster!

Thanks again!

You can also use a normal smart adapter without the optical expander element. The advantage of the expander optics in the Speed Booster version is the ability to get the lens angle of view closer to what it would be on a Canon camera. You have two choices, 0.71 and 0.64, the later which gets the angle of view close to a APS/C size sensor. This is what I use on my Picket for Nikon lenses.

If you go with a Soeed Booster, you want the one made by Metabones specifically for the Pocket 4K, vs the standard MFT/EF model.
Cheers.

Hey Matt, None of the lenses you mentioned, including the Sigma 18-35mm, will mount directly on the BMPCC Pocket 4K. You will need an adapter. I recommend getting the Metabones SpeedBooster .71x MFT/EF Adapter.

Great thanks a lot for your feedback, so that would be the one for me?

Canon EF Lens to BMPCC4K T Speed Booster® ULTRA 0.71x

And from what I read there it would also work with a Sigma if I eventually buy one.

Yes, the one with the name that is specific to the BMPCC4K (and not the original BMPCC which is completely different. Personally I’m still considering the version of that SpeedBooster that interfaces PL with the BMPCC4K. But a bit nervous about spending the money (next year?) if it makes the image softer.

Matthieu, one thing: when you are not intending to use MFT lenses with the PCC4k, but EF lenses only - why buy the PCC4k + Metabones adapter when you can now get the PCC6k with EF mount?
Saying "Thx for help!" is not a crime.

i find the 4k + speedbooster, even if it is now the same price as the 6k,
the better variant what the variety of lenses means.

the 6k is very limited and on the 4k i can use good cheap (for example meike) cine prime MFT,
or with an adapter i can use old canon FD, nikkor or lumix lenses.

also the limitation not to record in 4k BRAW on the 6k was a reason for my decision.

I agree, for what I shoot, the 4K camera with its current FW offers more versatility, and recording options.
Also I like the additional lens mount options. That said, if I was still working professionally, the Pocket 6K with the Wooden Camera PL mount mod would be a good option, especially if I needed 4K Deliverables. As it is, I only need UHD and HD delivery.

I’m a fan of the versatility of the BMPCC4K but the BMPCC6K shooting BRAW open gate does give you the option then of downscaling to 4K/UHD in post for even better detail and improved colour and wider field of view.

Then again with the addition of the Metabones SpeedBooster for BMPCC4K, your field of view matches true Super 35.

Yes it does Rick, you can get real close to the same FOV from a 35mm lens with a SB as you would have on a S35 camera, and get that S35 feel to your image.

Hey guys in terms of memory card I was testing with my 64GB Sandisk 48MB/s and my Blackmagic says "No Card", I'm guessing I need a different type of memory card.

I need to go with 95MB/s right?

Don't overspend on the metabones.
The Viltrox is totally fine. You'd be better off using the money you save on other stuff you might need.

Kristian Lam said

Since the pixel pitch of the Pocket Cinema Camera 6K is smaller, the 4K DCI crop on the Pocket Cinema Camera 6K will actually be more cropped in than 4K DCI on the Pocket Cinema Camera 4K.

We've maximized the formats on the Pocket Cinema Camera 6K for the greatest FOV and frame rates possible, so wouldn't it be better to shoot at 5.7k which is 17:9 (to match 4K DCI's aspect ratio) and also get the benefit of oversampling when delivering in 4K DCI?

Yes, the 4K crop on the Pocket 6K for Raw shooting, would be physically smaller than the full 4K DCS sensor image on the Pocket 4K, and IQ would not be as good. Shooting the 5.x crop for down sampling is much better IQ and FOV wise.

Sorry to say but this one is much better: https://www.metabones.com/products/details/MB_SPEF-m43-BTA

By the way, unlike the BMPCC has only a MFT sensor, the DOF is a little more than the UMP when wide open at 1.3.

That’s the SpeedBooster I meant, to allow use of EF lenses on the BMPCC4K with the improved mount. Thanks for posting the link so there’s no confusion.

Hey guys I have a Sandisk Extreme 150mb/s 128 GB that a friend gave me, it seems to be working with my Blackmagic I was able to film a test.

When I try to export it in my computer I have a .MOV file with no video, only audio, even though I see the image in my camera if I try to look at it again.

I'm guessing I am not filming in the right format or maybe the card is still the issue?

If you're just viewing it with a player, you might be using the wrong player. Bring it into Resolve and see if you can playback. If it is BRAW, use the BRAW Player. If Prores, on the Mac, you should be able to view both video and audio via the QT player. On Windows, you can try VLC as your player... usually works.

Thanks for the quick reply, I do see it in VLC you are correct.

I usually work with Premiere Pro I tried importing there and would only get the sound. Forgot about DaVinci Resolve 16 Studio that is included with my blackmagic, I'll get that going and start working with this one instead.

But would there be a way to use that footage in Premiere Pro? I was filming in ProRes

You should be able to. I just did a quick test capture with my BMPCC6K using ProRes 4K 422 HQ and brought it into Premier Pro 2020 and had no problem playing both video and audio.

Let me know your thoughts regarding the MinGW Runtime Assertion error with Resolve, I google and it seems to be a recurrent issue however I have not found the solution, I don't want to mess with it either.

On the positive, I went out and shot some great things, this Blackmagic Camera is a gift from God, I've been shooting with a Rebel T3i for 5 years+ so you can understand my excitement.

Hope someone can help with the error below, I have my Resolve software, the key everything, but no sucess!

No, an iGPU is not enough, and you can't use HEVC 10 bit 4:2:2 in the free version.

Re: (Rookie Question) Lens with Blackmagic Pocket 4K

As a suggestion, you can try uninstalling any Resolve products and deleting the installer. Some installer files may be corrupted. Download the latest Da Vinci Resolve installer again and retry to install.

Usually you will get such error if the OS or drivers are not compatible but I will assume they are. So I am assuming that there might be files that are corrupted.

Reading your computer (laptop) spec, Uli's recommendation should be considered. I don't think you will have a good experience running Resolve on it, assuming you get pass the starting Resolve error. Good luck!

Yeah no problem I open the question over there, otherwise I will try uninstalling as suggested.

But still shouldn't I be able to see them in Premiere Pro, any ideas why the file would only show up as Audio File?

I will definitely start shooting in HD with that in mind

You should update your NVIDIA driver, the installed one is from 2018.
Saying "Thx for help!" is not a crime.

Solved my previous issues and went shooting, thanks a lot for your help!

Back on topic on now regarding the lens, I've been shooting with the Lumix 35-100m that I quite enjoy, however I've been thinking about my Canon lens and how they would look/fit on my Blackmagic. I initially bought the Metabone Speed Booster but the company was back-order, and by the time I was waiting I got my Lumix lens so I decided to cancel the order because I have a shoot next weekend.

I decided to go with the Viltrox Mount Adapter EF-EOS M2 0.71x that I read would fit with my Blackmagic and my Canon lenses, I might've screw up because it doesn't seem to fit in my Blackmagic camera, probably the case. Let me know if the Viltrox Mount Adapter EF-EOS M2 0.71x is supposed to fit the Blackmagic, just didn't want to force it too much.

Also, I was able to mount a Canon lens (50mm 0.45m/1.5ft) on one side of my Viltrox. But when I tried my other lens that I actually want to use, a Canon (18-55mm EFS with Image stabilizer) it didn't seem to fit on the Viltrox. I could almost get it in but I wouldn't hear the click. Once again, probably me being a bit stupid and noob, I don't want to force it like I said.

Before I go further I wanted to ask your thoughts, I bought the wrong adapter right?

I use the Canon 18-55 kit lens on a discontinued Aputure DEC LensRegain wireless EF to M43 .75x focal reducer without issues. I've used Canon EF-S 70-200, 10-18mm and EF 20-35mm 2.8L lenses too. Although not specifically designed for the BMPCC 4K, it has several layers of coatings that improve the sharpness on vintage lenses that lack contrast. I haven't tried it on a super sharp lens like the Sigma 18-35mm though.

If people are reporting Moire problems using the Sigma 18-35 using the old Speed Booster on a BMPCC 4K, then what does that say about using the Viltrox focal reducer?

So the Viltrox Mount Adapter EF-EOS M2 0.71x doesn't fit in the Blackmagic right? It's the "EF M2" I should've got I think.

Would that work with my Blackmagic? https://www.amazon.ca/VILTROX-Reducer-B ... s9dHJ1ZQ==

In my local circle, I've heard complains about the Viltrox adapter having some play with the BMPCC4K mount, especially with heavier lenses that over the months they have been using it, had issues with the adapter mount being loose causing issues like difficulty in focusing and electronic communication between the camera and lens. I don't have a BMPCC4K so I just stating what I have heard. I have a GH5 and with that I use the Metabones and it's rock solid.
