If only DJI could add an option to turn off the ugly over-sharpening.

TowerJazz could be printing a licensed customized Sony sensor for any manufacturer who licensed it.

TowerJazz produces the sensor for S1R.

For S1 and fp, they use IMX410CQK-C.

Good overall colour rendering, but skintone a bit too magenta, A7 III is surprisingly better in this regard.

Perceived DR is quite high, but it's mostly the result of aggressive NR.

Do you know if there is likely to be a gap in-between the exposures when it's stacking the 16 frames?  Ie, can it do a full 360degree shutter.

If you have a subject with motion blur then you don't want there to be gaps throughout the blur.  This would be especially obvious with light-trails of headlights etc.

The 3D models thing is super-cool.  The problem with modular cameras is that the modules are flexible but sacrifice overall size compared to integrated designs.  Being able to 3D-print an accessory and not having to adhere to the standard sizes for mounts, mount adapters, and the like would be great.

ISO6 is intended for landscape photography.

It uses IMX410, just like Z6/S1/Zcam F6

Due to the removal of a mechanical shutter, flash sync speed is an appalling 1/30s.

Honestly, they can lock them in at iso100 for all I care. Been dreaming a long time for a base iso 50 or even 25 in a camera. 

The ISO 6 looks tasty even though I suspect it's a pull from 100.

ISO 6 is achieved by in-camera 16-frame stacking.

IMX311 employs an innovative 45 degree diagonal pixel array with BSI and stacked design, it can output 96MP/24MP RGB RAW stream.

Other new products include:

IMX313, a high speed 48MP BSI Stacked FF sensor:

IMX409, a low cost, high resolution and high speed 54MP BSI FF sensor:

IMX521, a high speed, high sensitivity Quad Bayer 15MP BSI FF sensor:

IMX554, a ultra-high speed 30MP BSI and stacked FF sensor:

Then it is not the same sensor is it.

The IMX series are the off the shelf sensors sold by Sony. They do not include the modifications that exclusive clients might use in their designs. The general fabrication might be similar, but they are not the same sensors.

Some people buy cameras with kit lenses, some buy body only. Different SKU, but same product.

A bit more details about some of the recent Sony Semicon FF sensor portfolio:

15MP Exmor R 7.52um 16Bit HS SLVS-EC 8Lane
24MP Exmor R 5.94um 14Bit HS SLVS-EC 8Lane
24MP Exmor RS 5.91um 14Bit DRAM SLVS-EC 8Lane
28MP Exmor RS 5.5um 16Bit SLVS-EC 10Lane
28MP Exmor GS 5.5um 12Bit SLVS-EC 12Lane
30MP Exmor RS 5.31um 14Bit UHS SLVS-EC 8Lane
36MP Exmor RS 4.88um 16Bit HS SLVS-EC 16Lane
42MP Exmor R 4.5um 14Bit SLVS-EC 8Lane
45MP Exmor R 4.35um 14Bit LVDS 12ch
48MP Exmor RS 4.2um 16Bit DRAM SLVS-EC 8Lane
54MP Exmor R 3.96um 14Bit SLVS-EC 8Lane
60MP Exmor R 3.76um 16Bit SLVS-EC 8Lane
100MP Exmor RS 2.91um 16Bit SLVS-EC 8Lane

Another interesting sensor from Sony Semiecon, a 48MP FF sensor with diagonal pixel arrangements, sounds familiar?

RX100V has 315 phase detect points. Can't be the same sensor in that case.

I am not sure why someone would want the Canon when the RX100VA/VI appear to be better cameras. Plus, there should be a RX100VII arriving soon, which presumably will be a step up from the older models.

Same sensor but without pdaf mask, just like Pana S1/A73.

I see Canon just announced new cameras with Stacked 1" sensors.  I guess Stacked sensor are old tech now with the GS sensors coming.

They use IMX383 from Sony Semicon.

How's it better than OLED?

A lot brighter (2900nit peak) while having similar black level. No burn-in. Lower cost.

The 65inch model is about 2200EUR.

Hisense just announced an HDR display with "Dual Cell" technology from BOE, it's a 4K display but with a 1080P monochrome panel "sandwiched" between the 4K panel and backlight unit, essentially offering over 2 million backlight "zones" (1 zone per 4 pixels).

Peak brightness is quoted to be 2900nit with over 150000:1 static contrast ratio. It's also the world's first panel to be able to reproduce 16bit gradation. 

Current size is only 65in, but there are plans to introduce 55in and smaller sizes.

The new 54MP FF BSI is low cost, has relatively high speed (full sensor readout at 12bit 25.6fps), and very fast AF with dedicated AF lane.

Sony Semicon readies a whole new portfolio of sensors for consumer stills cameras:

15MP FF BSI
30MP FF BSI Stacked
48MP FF BSI Stacked
54MP FF BSI
25MP 4433 MF BSI
50MP 4433 MF BSI

A9 II and a RX 1inch camera will be the first cameras to be equipped with Exmor RS sensor.

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.
