So is this what it has come to? Is the next report going to be a sighting of Sasquatch filming tourists with an Ursa 4.7K?

So,even after this much discussion on Ursa4K upgrade and the promised 4.6K turret,why this black magic design company is keeping their mouth SHUT!!!

Ashok.


It may be all about harm reduction for the company. Until the wizards can find a technical solution or the sales-folk can wean the remaining big URSA owners off those still working cameras, nothing more will be said because there will be nothing new to say. There may be too much legal risk exposure from the company even publicly discussing the topic beyond the announcements already made.

I know that 4.6K or more would be a bonus. If it is just the wider field-of-view you want and a bit more low-light performance, you can achieve that with a custo ount and a Metabones 0.71 power focal reducer optical cell when using cinevised DSLR lenses like Zeiss CP2, Xeen, Rokinon/Samyang Cine which do not have rear optical elements closer to focal plane than about 40mm.

Unfortunately, many traditional PL-Mount lenses are not suitable for using with a focal reducer.

I do believe that the sensor on this turret would make more money being released on a new camera than being sold alone, and even if released alone they could always push up the price way crazy just to keep ursa users who are complaining quiet.... they are however specs and nice pics of it available here on videotoybox

I also do believe that there is alot of merit in the fact that a major selling point of the big ursa was future upgrade ability , meaning that blackmagic has a commitment to its buyers to keep supporting the camera because this was a feature that added to the high selling price of the big ursa at the time and funds should of been kept aside for this. that being said, should the sensor be released -
the sensor on the URSA would be a game changer and cut sales on the ursa mini , having more features than the ursa 4.6k sensor... , why would people buy a whole new camera that blackmagic hopes to release soon ... maybe we should start a change.org post. ??

6 months ago black magic design company CEO told that the development of the turret for the Ursa is going on,but no further news from him yet!!!

Exactly, Asok Kumar! If they were planning to quietly drop it, why on earth would you have the coo say this and post it permanently on the board? I recently ordered the adapter from Luca Butrera, hasn't arrived yet, but I pulled the old beast out of its box where its been sitting for a year and did think "This is such a great camera!"

Patrick. If Luca's adaptor works like the Metabones Ultra optic, I think you will be well pleased along with being able to use EF lenses which my own mod did not enable. - I did not bother as I have Nikons but I probably should have because I also have EF-adaptors.

Im interested to see what frame size it'll compare to. The Ursa 4k is pretty small for s35, the 4.6k is pretty big for s35. I doubt the ursa major with the adapter will hit FF, who knows? I was hoping my sigmas might still cover it, with the booster and a 1.8 zoom, it turns it into an unexpected low light machine!!

I'm still hesitating as to whether to sell the Ursa. Every month that passes means a drop in my potential selling price. A little news is better than no news at all.

Seriously how long has it been? How long overdue is the turret? The URSA is dead, they are not updating firmware and there is a post here showing that replacement part are not even available. BM doesn't give a crap about you they have proved that already, move on or fight back but this blind Faith is rediculous.

I just received the lucadapter today and fitted it to my big ursa. Its really amazing, easily adds a stop or so more light - in fact it seems better in low light now than my mini at 800.
With this mod, that also gives a much more usable frame size, I would settle for BMD at least updating the firmware on the big ursa to bring it in line with the 4k mini, The 4.9 os with this adapter and no black hole sun, would make this still a relevant camera.

The speedbooster is a serious improvement. If BM could do a fix for the black hole sun or in my example magenta hole sun, that would be a bonus.

If you are offering up a new lens to the camera which looks like it could go a bit close to the speedbooster optic, cut a paper disk and put in between the new lens rear element and the speedbooster front element.

Leave the paper disk small enough that it can slip around a little bit but large enough in diameter that the centre of the lens elements will always be covered. Put the paper disk in whilst the camera is in its normal operating position.

Fit the lens as normally. Turn the camera upside down and give it a slight shake. Place the camera with the lens facing directly upward.

Dismount the lens whilst the camera is facing directly upwards. If the paper disk has not moved and remained in a new position against the top edge of the space it sits in, there is a fair chance the paper was trapped between the two glass surfaces and could not move when the camera was turned upside-down.

If the paper cannot move because it has been trapped, it is likely that the rear element of the lens and the front element of the speedbooster will touch and become damaged.

The black hole sun on the 4k is not fixable in camera. Unlike the pocket camera which had the ability to differentiate between an overloaded pixel and a dark pixel the 4k sensor has now way of reporting if a pixel is dark because it is overloaded or dark because it should be. Only software that attempts to determine if it is one or the other is possible. As such there is a risk for false positives and BM wisely has added the fix as a post processing solution in resolve giving the user more control and options. In short black hole sun fix will probably never happen in camera.

The black/magenta hole is an enduring memory then. It was a good notion whilst it lasted but not impossible to deal with. Overcooked thin misty cloud does sort-of faint green-khaki things to the blue sky seen through it but that is a matter for the cameraman to manage properly.

The extra ISO400 or so does require a little re-learning for the likes of myself.

That's a shame about a software fix for the purple hole sun - I can't see it in my viewfinder, only if Im using the big screen It's quite a specific shade of magenta, and being that it's always surrounded by other pixels that are clipping, I would have thought they could safely code for those circumstances. Even if it was unpredictable, it could be a switchable in an os update. The mini 4k with the same sensor I believe does not exhibit the phenomenon.
If the turret is not coming, I'd be happy with the camera now with the extra stop if the OS could be brought into line with the mini 4k. Having the option to use luts would be a huge bonus - in addition to having the option of monitoring luts, I'd also like to see the option of recordable baked in Luts for fast turnaround.

The 'Version 2' sensors - which are supposedly tweaked a bit - don't have the sun spot. The 4K URSA Mini and the V2 turrets have this sensor. Maybe V1 URSA owners can find V2 turrets on the used market if it's worth it...

I don't understand why bmd is discontinuing the big Ursa,if the body weight is the problem,the arri Alexa is equal or more weight than Ursa,the newly launched Sony Venice with all the ESSENTIAL accessories weight more than Ursa,and this much extensive discussion on the Ursa turret reveal how much the handsome Ursa is in the people's heart!,ower Grant pretty is not hearing it,or purposefully he is shutting his eyes and ears closed?

The answer is simple BM is a business if there was enough demand for the big URSA they wouldn't be discontinuing it.

Here's the real reason: it's for the wrong audience. It's designed for an Alexa user who doesn't care because he/she gets to use an Alexa, but priced for people who don't know what an Alexa is. The Mini fits BMD's market perfectly... because it suits their needs and budget, since most are one person crews.

Both are good cameras, but the big Ursa isn't a great seller to people who mostly operate as one-person-bands because it was designed around a crew rather than singleton.

Hi Patrick

Please could you post some footage would love to see it in action. And thoughts on it...is it soft around the edges?
Also do you think the mosaic moire filter would fit with it - if they still make one to fit the ursa major?

Ta.

Thx

I had a Version 2 URSA and it still had the sun spot. The Mini did not.

Exactly. My UMP has the black hole sun in certain situations. You are never going to 100% never have it appear in certain situations. It happens in Alexas too, well I can't confirm that on the Alexa Mini or Alexa 65 :)
