BMPCC 6K S35 raw camera, war on Z-CAM

I am sure within 6 months we will see both E mount and RF mount for Z-CAM. I mean here also third party changeable mounts at least some of firms are looking to them such.

I also think China-US trade war will change landscape a little, as many Chinese firms will fully scrap any patents/intellectual property respect.

I doubt it.

No camera has ever been E mount that isn’t built by Sony (not counting a useless dumb mount on kinefinity)

RF is unlikely too. I suspect Canon have allowed it on komodo as an IP swap for Redcode.

Mounts are a problem in this weird market between traditional cinema, vintage stills and mirrorless.

I guess E mount or Canon RF mount.

brudney

Interesting, any rumors on which mount they intend to use?

@brudney

Rumors are that we will see real 6K, smaller, with FF mirrorless mount and around 50% better battery life and better thermals at NAB 2020. BM told to early testers that they just need to close the gap to prevent competition from gaining sales, so it is little rushed.

Unsurprisingly, looks just like the 4k version. Not sure if SLIGHTLY bigger sensor justifies the hike in price and the hassle with much bigger files.

The footage I haves seen from this camera looks better to me than 4k. The motion cadence is much improved, it does not have that video look the 4k version have in some videos.

Blackmagic did release the Production Camera 4K years ago. It had a global shutter. Too bad they never made an updated version with 4K 60p.

It can be had for under $1,000 used now.

This is crazy. Here P4K orders are at a slow pace and they've announced a 6K version. Wow. I like the thought of a S35 though and I have some EF glasses. I'll wait a little bit until they're selling - we're still at the P4K order fatigue, I think. ;-)

same crappy battery life

@suresure123 Blackmagic already noted few years ago that global shutter mode was degrading image quality on URSA 4.6K so much that they had to disable it. ( By the way they are using their own sensor on that camera. )

Most professional cameras, including ARRI ALEXA and all flavors of RED use rolling shutter sensors, because they have better DR. It’s not a matter of having rolling shutter or not, it’s readout speed of the sensor what really matters. With fast readout you effectively reduce rolling shutter to barely nothing

@davedv

So it's possible that Blackmagic is using the same sensor, but just cropping in a few more pixels from the edge to get to an even 6K (1024 x 6 = 6144) resolution.

If BM will start using Sony sensors it will be big changes for industry.

Despite all fake openness all advanced large sensors are guarded by Japanese manufacturers and no way you can simply get them for making your camera, except if it is small batch niche thing or industrial stuff.

MFT and 1.5 crop? One more interesting thing is autofocus. If it's like fuji, I am all in.

The effective sensor size of the Blackmagic Pocket Cinema Camera 6K is 23.10mm x 12.99mm with a resolution of 6144 x 3456 (16:9 aspect ratio). In terms of horizontal field of view, this would be a 1.55x crop compared to shooting 16:9 on a full frame (36mm x 24mm) sensor.

This is a bit higher in resolution than the 23.5 x 15.6 mm sensor (6000 × 4000 pixels) used in the Sony a6500 and a6400. It's pretty similar in specifications to the 23.5mm x 15.6mm sensor (6240 x 4160 resolution) used in the Fujifilm X-T3.

The Fuji X-T3 was speculated to be using the Sony IMX571 sensor (https://www.sony-semicon.co.jp/products_en/IS/sensor2/img/products/IMX571BQR_Flyer.pdf), which has a pixel size of 3.76 μm. If you use that pixel dimension with a resolution of 6144 x 3456, you'll end up with exactly the same effective sensor area as quoted by Blackmagic (23.10mm x 12.99mm). So it's possible that Blackmagic is using the same sensor, but just cropping in a few more pixels from the edge to get to an even 6K (1024 x 6 = 6144) resolution.

That sensor has a maximum full resolution (6244 x 4168) read-out speed of 48.42 fps, but perhaps by cropping the vertical resolution to a 16:9 aspect ratio, the sensor is able to achieve a 50 fps readout (which is the highest full resolution frame rate supported by the Blackmagic Pocket Cinema Camera 6K).

Agreed, global shutters are long overdue.

suresure123

What drives me nuts with these pocket small form cameras is none have a global shutter!!!!! It means by the time you rig it up you may as well have a more bulky camera. The consumer market is showing the way in this are with the Olympus IS which is almost as good as a gimble. The URSA has a global shutter, it can be done. Its a shame cause these cameras real niche is documentary handheld run and gun and they keep failing at this. I will happily lose a bit of Dynamic range for a global shutter before anyone says it and I will pay more for it too.

hardimpact

I don't think this is very impressive at all. same dynamic range as bmpcc? i hope they're joking. That one used the same sensor as the gh5s which is pretty low. My money is on the sony sensor used in the panasonic s1. at 10 bits, it has no price comparison and its dynamic range is about 2 stop better than bmpcc or this one (which seams to simply be a larger version of the old sensor, not a better one)

Faudel

@DrDave Cant tell about the sensor but the crop factor relative to FF should be : 43/sqrt((23.1)²+(12.99)²) :p

Howdy, Stranger!
