New firmware announcement around IBC as well ?

As you may be aware, Fujifilm has registered three new cameras:

FF190001

FF190002 – X-Pro3

FF190003

One of them is a 44 x 33 large format video centric camera with 4K x 3K RGB output.

 

Expect a relevant announcement at IBC later this month.

Readout speed is believed to be ultra fast at < 12ms.

How does that translate into noise, sharpness etc?

Thanks

4K pixel to pixel has a bit more noise than supersampled 4K from 6K. A bit softer as well with some moire/aliasing.

S1H is even more soft but with reduced moire/aliasing due to the addition of an OLPF.

What's the difference between the two modes then? They seem to have different codec options, etc. 

4K pixel to pixel/S35 goes up to 60P and has a bit less rolling shutter (16ms vs 21ms).

Pixel / pixel should be around 2 x crop, right? Also perhaps a little noisy? 

I find Ex Tele Convert (crop mode) footage in the GHx range doesn't always cut well with full sensor footage. It's the noise grain and sharpness that dont always match well. 

On S1 and S1H, 4K pixel to pixel readout is the same as S35 mode, it's a 1.5x crop.

Being a little off-topic: @androidlad, since you always have good info on sensors, any news about newer m4/3 sensors?

What sort of anamorphic lenses would cover 44x33 sensor? Answer: None of them.

They are nearly all S35. Very few medium format anamorphic lenses out there... maybe for VistaVision somewhere in Hollywood?

That's why the S1H anamorphic mode is only S35

How do we know the slides are from that of a new cam, and not just the GFX 100 (as it's the same sensor)?

There are quite a few large format anamorphic lenses for Alexa 65 that fit GFX.

It’s a new cam because it’s a GFX with X-Trans IV CFA.

Finally also Fuji in Anamorphic mode. I am using mostly anamorphic lenses on my X-T3. Any idea if this will be in APS-c as well?

 

Would be great to implement a 3 x 3 colour aware binning on X-T3 for 2080 x 1386 RGB, but I think it’s unlikely because colour aware ADC is introduced in 3.76um gen 2 sensors (IMX461XTK)

A $ 10,000 GFX100V?

3882 is enough for 4KUHD not for 4KDCI.

What’s this solution? A binning picture with moiré and aliasing at 444 color resolution? 

 

It’s an anamorphic mode.

And due to a 3x3 colour aware binning, it’s completely free of moire/aliasing, also with drastically increased sensitivity. Kinda similar to those 48mp > 12mp smartphone sensors but much much more advanced.

3882 x 2912 x 3(RGB).

What was to stop Sony using their own Fuji X-T3 sensor in the A6600 and at least make it compete?

Or was the sensor a Samsung part after all?

Is Sony really telling APS-C users in 2019 that they don't quite have the technology to do 4K/60p or reduced rolling shutter on a crop sensor? No 10bit?

Honestly buying a 2016 cam in 2019 just seems a bit of a waste of time.

Sony Professional Video division negotiated with Sony Alpha to reserve IMX571 for its future pro camcorder products.

Could do with the AF improving, firmware 3.0 seems to have made it worse than it was

Yes the upcoming new firmware addresses the AF issue.

There will be a new firmware announcement around the same time as a new product announcement.

a6100: IMX210
a6600: IMX284

Arriving in a few hours.

4K video on M6 Mark II is derived from pixel-binned 3.5K Bayer output. Disappointing.

It's still the IMX410, full pixel readout can only go up to 40fps @12bit

Rolling shutter performance:

7680x4320/24.7ms
9472x3996/22.2ms
6144x3456/19.9ms(Low Noise)/13.5ms
9472x1332/8.1ms
7680x1080/6.7ms

According to last informations, today will be announced new codec and new sony camera in China. Does anyone know more?

A global shutter 3 CMOS ENG camera PXW-Z750 was announced. XEVC not yet.

Shouldn't a speed booster shorten the focal flange distance? Do you have a different optical assumably designed so that this doesn't have to?

As it's EF mount, would it work on C200 or EVA1? 

It's been pointed out multiple times in this thread, that this speedbooster sits completely within the mount as a set of pure optical elements, it does not alter the EF mount in any way therefore does not change the focal flange distance.

There are accessory mounts for gimbals that allow you to mount anything from mics to monitors. With a shotgun mic on a shock mount it’s good enough to capture ambience.

Regardless of the output bit depth, they are all derived from linear 12bit readout, there’s no discernible DR difference between 10bit and 8bit on the same camera with the same picture profile, the benefit is flexibility in grading (4 times more bits per stop).

Some pretty impressive rolling shutter results for the 6k as reported by Captain Hook on DVXuser

Full 6K : 19.73ms
5.7K crop : 16.26ms
2.8K crop : 7.98ms

Literally the same as XT3.

And literally the maximum permissible rolling shutter given the framerate.
