Fuji only does 17:9 and 16:9 in video, but this may change in the future.

While it doesn't have the flares and ovals bokeh, IMO, video shot with the GFX-100 looks anamorphic. It's sharp edge to edge... clean. Almost like a modern anamorphic. Yet has an aesthetic that smaller sensor are missing. This must be to do with the "medium" format look. I feel it looks quite cinematic.

What are your thoughts? 

 

It's all to do with FOV. A 50mm 2x anamorphic lens has a horizontal FOV equivalent of a 25mm spherical lens.

On a GFX, a 63mm lens has an FOV equivalent of a 50mm lens.

Some people call it "grandness".

The 60MP IMX455 now has a 15MP Quad-Bayer variant, D6 anyone?

Its 12 bit prores raw.

I dont think there are any cameras on the market under $20k excluding the RED cams and Sony Cine Alta F5 that do 14 bit raw video. 

Magic Lantern does 14bit RAW

@androidlad what benefits from global shutter?

 • eliminate jello?

• record at any fps?

• what's lowest ISO / does it eliminate need for ND filters?

• for stills, sync flash at any shutter speed.....central leaf shutter lenses no longer needed?

The primary reason for Sony to introduce global shutter to consumer digital stills cameras is to completely eliminate mechanical shutter (no shake).

I am not. If pixelsize is the same, bigger sensors have higher pixel amounts. with the 3.91 micron pixels there is the 26MP APS-C sensor, the 100MP 44x33mm medium format sensor and the 150MP bigger medium format sensor. A 60MP full frame sensor seems to be in the pipeline. And if you crop one of those sensors to the size of one other, it has exactly the same pixel count. 

The pixel size is actually 3.76um, the 60MP FF sensor, IMX455, is already being sold to third parties, including Zcam E2 F8, Nikon and Pentax.

So, it doesn't have any other mode, for shooting 4k and other video resolutions, I am guessing? Also, what exactly were Fuji saying wrt to the mode or method of controlling rolling shutter? Any idea of the rolling shutter on other MF Sensors/Cameras? 

On a Sony sensor, the only ways to reduce rolling shutter is to readout fewer pixels (especially vertically) and drop readout bitdepth.

I was wrong about the readout methods on GFX100.

In 4K, it supersamples the full width of 11604 pixels, and vertically line-skips 2/3 from 6527 pixels, resulting in a final bayer of 11604 x 4352 pixels at 11bit, then it's downscaled to 4K UHD/DCI.

4K rolling shutter is around 30ms.

Stills mode electronic shutter scan rate is 1/6s.

@androidlad before I get excited further , what is dynamic range of Exmor GS, please?

I believe one of the first Exmor GS sensors is 42MP FF IMX651, DR is similar to A9.

Hey everyone,

After much deliberation, I decided to go with the x-t3. It came through last week, and whilst I haven't had enough of a chance to play with it as much as I'd like, I really like it so far. The 120p footage looks great, as does the eterna profile.

I was hoping for some input on lenses (or adapters more specifically). Ultimately I'm after a fast(ish) prime, something around the 50 - 90mm full frame equivalent range. I already own the Tamron 45mm f1.8 VC (Canon mount) which fits the bill (albeit a bit bigger than ideal), plus it has stabilisation, but I'm wondering if anyone knows what video AF is like with adapted lenses?

The following adapters have come up on my radar so far:

Fringer EF-FX Pro II (which can be had from around £300 but looks like they all need to be imported)

Kipon Baveyes (similar price to Fringer, but with speed-boosting optics, although they seem to create artefacts. Also needs to be imported)

Viltrox make both speed-boosted and regular adapters that can be had for around half the price of either of the above.

 

Would really appreciate any input / knowledge on AF performance, thanks!

If you want reliable continuous video AF, forget adapters. Go with Fuji's f/2 primes or f/2.8 zooms.

Funny that they shoot film simulations at DR100 and complain about the limited dynamic range.

Oh ok. Is there more than one Medium Format 43.8×32.9mm sized 100MP sensor available right now? Or in suspected to release in the very near future? 

100MP 44 x 33 IMX461 is the latest one. We might see a 170MP one in 2021.

IMX555 is a FF sensor and won't be out till 2020.

Do you think it's likely Sony will sell Exmor GS sensors to Panasonic (GH6) and Fujifilm (X-H2)?

No. It's a speed-oriented sensor line-up with the elimination of mechanical shutter mechanism in mind. And it'll likely to be Sony exclusive for a while.

I'm fairly sure X-H2 will move onto the 2.91um gen 43MP Exmor R.

This is exactly what happens when pan axis is locked, instead of follow.

Apparently @MaxYuryev just joined, welcome

A leaked slide, relevant?

Sounds like the pan axis is locked.

I would assume if it made it into mass production it’s for the production of products mostly likely professional cameras.

EDIT: looks like misty industrial applications.

That press release was from 2015.

will Exmor GS make its way into Sony A6500, A7sII and A9 successors?

A hint: Exmor sensors are used in smartphone cameras, consumer/prosumer DSLR/mirrorless cameras, and cinema cameras.

Sony's new line of professional imaging sensors, Exmor GS, has entered mass production:

This is a new additional to Sony Semicon's current sensor line-up for consumer/professional imaging:

Exmor R (Reverse/BSI)

Exmor RS (BSI + Stacking)

First proper video I've shot on the GFX 100:

Didn't have much to knock this together, but the camera did a pretty respectable job, especially as the last two shots are at 2000 ISO. The whole video was shot in Eterna.

Unfortunately, the DR+ profile did not seem to be functioning properly, so blacks were quite crushed in the captured footage, unlike what I was seeing in my histogram and external monitor. I'm optimistic that this will be fixed when we get production cameras.
 

Nice work. Are you sure the crushed blacks wasn't caused by this?

Did you edit the GFX100 footage on Mac?

Cropped 2.39:1 just doesn't look as authentic and visceral as true anamorphic cinemascope. X-T3 is capable of full open gate 6240x4160 12bit readout at 30fps, with 31ms rolling shutter, if combined with 1.5x anamorphic lenses it'd be a dream setup.

I just doubt its going to happen considering prores RAW has been 12 bit not 14. Nikon hasn't hinted at anything more. 

ProRes RAW can be 14bit, DJI Zenmuse X7 records certain resolution/framerates in 14bit ProRes RAW. It's no higher than 24P.

But for the sensor Z6 is using, it cannot achieve video frame rate using 14bit ADC.

It's not impossible. Nikon and especially Canon are doing similar task for their sRAW for years, though the result is softer than native lower resolution image. The problem is it needs significant and constant CPU processing which Z6 is not designed for. 

 

sRAW is not true RAW, it’s debayered.

If it's true RAW then it's impossible to do 4K from 6K sensor without crop.
