Canon not going global shutter with next round of EOS R camera bodies

[Michael Clark]

But my question is : Didn’t RED cameras solve the issues of Dynamic range with their Komodo cameras and global sensor ? Don’t they advertise like 15+ stop of Dynamic range and they are used in cinema where dynamic range is a most ?
Can somebody explain that to me ?

Cinema can get away with slower exposure times. Anything more than 2X the frame rate is acceptable. Anything more than about 4X the frame rate starts looking jerky instead of smooth when there's motion in the scene. 1/60-1/125 are commonly used and anything shorter than 1/250 is rarely used for 24/30/60 fps work.

Stills is an entirely different ball game. Sports & action need 1/1000 or shorter for top quality work. 1/1600 or 1/2000 if you can get there without pushing ISO too high.

Provided it has adequate dynamic range, I think Canon's 19 MP GS sensor may be enough for the R1 II.
Although, folks would make the 5 MP difference sound like the end of the world.

Maybe for the R3 II if there ever is such a thing.

The R1 will have nowhere near that few numbers of pixels.

I tried that site, clicked on the R3, my r6m2 the 1DX III, nice stuff. Then I clicked on what should be my first Canon digital, the XTI and I had to look twice to find it, almost like there was an eyelash on my screen. Come out with 20 more cameras with bells and whistles I haven't even heard of yet, I will stick with my R6m2's and keep buying glass. Glass. Glass.

The Rebel XTi was the 400D, which for some reason Photons To Photos skipped. They have test results for the 350D (Rebel XT) and the 450D (Rebel XSi).

I don't know if anyone has tabulated them.

The measured base ISO of the EOS R is actually 66. You can check DxOMark (e.g. for the EOS R), measurements tab, ISO sensitivity and hover over the ISO 100 point to see the measured value. Bill Cliff (photonstophotos) gets his source data from DxOMark.

That's not necessarily base ISO of the sensor, it's the effective ISO when the camera is set to ISO 100. There's probably still some analog amplification going on at that setting.

 

[Michael Clark]

No, Bill Claff gets his data (source raw files) from the users of respective cameras.

At some points he shows the data he gets from users. In some places he does show DxO data as well. It all depends upon which of his charts you're viewing.

 

[Michael Clark]

Wait, the A9III can't record 240p 1080p but the R3 can with autofocus?! What?

I think you meant 240fps at 1080p?

R3 has 1080p/FHD at 240fps in ALL-I. At the moment Sony did not say there's 240p, up to FHD 120p.

Stills is an entirely different ball game. Sports & action need 1/1000 or shorter for top quality work. 1/1600 or 1/2000 if you can get there without pushing ISO too high.

To justify a global shutter over a fast stacked sensor would take 1/4000 at least.
Sony is bragging about 1/80,000.

? 240p means 240 progressive scan.

Will @Michael Clark admit that he was incorrect? I won't hold my breath.

Yes. But what you said was 240p at 1080p, not 240fps at 1080p.

 

[Michael Clark]

Leaning into the saying: 20/20 is not perfect vision, it’s the average. 20/10 would be actually impressive

Back in my younger days I had 20/15 with RGP contact lenses.

Ok. I've never noticed that usage before. I guess there wasn't room on the screen in the menus to put fps so they decided to use "P" (notice it is capitalized in the camera menu displays) instead. It seems to mean "frames per second" in this context, rather than "progressive scan", though, as there don't seem to be any options for interlaced scan so everything is progressive scan.

It seems rather odd to me.

I don't follow what you are getting at here?

You've said many times that I'm never wrong. Who am I to disagree?

Does Sony now also use the same nomenclature? 240P instead of 240fps?

For a long time 240p would have been understood to mean 240 lines of resolution, rather than 240 fps.

Wrong again. I’ve said many times that you are apparently unable to admit that you’re wrong. Thanks for proving me correct on that yet again.

I don’t know what to tell you other than use Google? It’s incredibly widespread from all camera manufacturers that I can find. So it’s not just Canon - even every Fuji camera I have shows the same thing in its menus. Perhaps cameras wish to distinguish image fps versus video frame rate? Do you shoot video?

There is still no indication that the A9III can shoot 240 FRAMES PER SECOND video in HD or 4K, even with its mega fast sensor readout.

 

[neuroanatomist]

I'm wrong.

Edited to make a false statement true.
