12MP, if not cropping, Enough for Most Average Photography Needs?

12MP, if not cropping, Enough for Most Average Photography Needs?
androidlad replied to SRV1981's topic in Cameras
Low pixel count cameras tend to be cleaner at high ISO because of the lower cumulative read noise. It has nothing to do with bigger pixels collecting more light. However, with the latest sensor design, it's doesn't alway apply any more. A1 for example, despite having 50MP, is slightly better in low light when shooting video compared to A7S III. -

Larger pixels don't gather more light. FF sensors are the same size at 36mm x 24mm, they gather the same amount of light with the same aperture. -
The 14bit readout only gets you ~0.3 stops of additional DR compared to 12bit. Also 14bit readout is 10ms rolling shutter vs 5.6ms in 12bit.

X-H2S is a speed centric camera, it's the very first stacked APS-C sensor and also the fastest, which benefits both stills (action, sport, wild life etc.) and video.
-
1/180s 12bit readout speed (Film sim, F-log, F-log2 >30fps) 1/94s 14bit readout speed (F-log2 <30fps) It's the first cosumer camera to use 14bit readout for video, however the DR improvement is very little based on Gerald Undone's test (less than 0.5 stops improvement).

It's called Grid Type in Z9 settings, there's one each for stills and video: https://onlinemanual.nikonimglib.com/z9/en/15_menu_guide_04_g11.html

The two new X-H cameras both use Sony Semicon sensors, they incoporate some of the latest technology from IMX610 (A1) including DBI and Sigma-Delta ADC.

Again the root cause is indeed the X-Trans CFA. Fuji uses a demosaic algorithm for video/jpeg that prioritises speed and efficiency in a small camera body. This leads to colour smearing issue. It doesn't happen to X-Trans RAW stills anymore because modern RAW processing softwares have much more refined algorithms to deal with X-Trans.
-
Nice video, inquisitive as always. This is mostly due to the nature of X-Trans, there are far more green photosites than red and blue, compared to traditional Bayer sensors, hence the less detailed Cr channel. The benefit is that it naturally reduces moire and it has a bit cleaner luminance detail (Y channel). You won't notice this on videos shot on Fuji GFX cameras which use Bayer sensor.

In the OM software "OM Workspace" yes, but not internally in-camera.
-
It seems OM1 has really good internal NR, applied at RAW debayer level: https://www.geh-photo.org/post/die-om-1-im-praxistest?continueFlag=143e81367b1d01290587846ff81073b9 Left EM1X, right OM1 OM1 ISO40000, yes forty thousand.

Lenses are putting a practical limit on DR to 14 stops?

Get a used TITAN X or XP from ebay:https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313&_nkw=nvidia+titan&_sacat=0

The sensor is capable of outputing 44fps but A1 is limited to 20fps at 14bit, while Venice 2 8K will run the sensor at full power.

First glimpse of Canon's true flagship mirrorless slated for 2022: 54MP 9000 X 6000 resolution with 4um pixel size Quad Pixel AF 1/450s sensor readout (2.2ms rolling shutter) Dual-15bit Sigma-Delta ADC Fully electronic shutter with no mechnical component (same as Z9).
-
Similarly, if you look really hard you can see the "stitching lines" on some shots showing skys in Miracle on the Hudson shot on Alexa 65, because the sensor is "stitched" using three A2X recticles.

It's official: https://pro.sony/ue_US/products/digital-cinema-cameras/venice2

Sensor is based on IMX610 from α1, but with 16 SLVS-EC 4.6Gbps lanes, intead of 8. The sensor itself cosumes over 5W power. There's no DRAM. ADC operates at 14bit at 1/250s readout at all times (meaning 4ms rolling shutter in all recording modes). Later paid firmware updates may unlock 8.6K 3:2 open gate up to 72fps, 8.6K 2.39:1 up to 120fps.
-
It's a leak, full info hasn't been released yet. Based on the framerates above, it will very likely do 5.8K 2.39:1 at 120fps.

Atomos Ninja V+ 5.2" 8K HDMI H.265 Raw Recording Monitor
androidlad replied to Emanuel's topic in Cameras
Atomos also needs to go fanless, it's way too audible. Z9 did it.
