You may find this relevant.

The closer you are the more important it will be to locate the entrance pupil ("no parallax point") Here's an extreme example. This image is 360 degrees: It's best viewed by zooming in so the image ...

You haven't read the entire 790 page Reference Manual ? :-D Page 634 "Beep" indicator. (Aha! I see I was edged out by 9 minutes!)

Are you sure the labels are the same? Black looks like 7D and blue looks like R7.

That's covered in detail in the Further Reading section below the chart and table But the quick answer is that the measurement takes the standard Circle of Confusion (which varies by sensor size) ...

Canon EF20mm f2.8 USM Matches drawing from repair manual more closely than construction in the Canon Museum. Unusual that they differ.

Nikon AI Nikkor 24mm f/2

Canon New FD50mm f1.4

Yes, the dark measurements (DSNU etc.) and Sensor Heatmap visualizations  at PhotonsToPhotos are for very short exposures. At 30 seconds you are almost certainly seeing the effect of Dark Current ...

Yes, interesting that the High Conversion Gain (HCG) FPN is more horizontal than vertical. Must view "original size"

We definitely agree there. :-D Thankfully I never agonize over whether any of my photography is "art".

These images appear to be from the PhotonsToPhotos Sensor Heatmaps . It's very important to view such images at "original size" You don't indicate which settings you used or provide any links. Here ...

So I suspect that my artistic use of negative space in this photograph undoubtedly violates the copyright of some prior art. ;-)

My impression is that you do need to settle on a brand first. It sounds like you would be looking for a FF mirrorless body with a relatively high pixel count for the cropping you anticipate. You ...

You are seeing something called perspective distortion. If you want to compose a picture with the subject not centered and want to avoid perspective distortion I suggest you try to crop the desired ...

From tests I would say the D5 over the D850 by about 2/3 stop. From the table below the chart Low Light ISO EV of 11.17 for the D5 versus 10.36 for the D850. Clearly the story is different when ...

Highly unlikely to see a patent published for a lens that isn't even on the road map..

Olympus M.Zuiko Digital ED 8-25mm F4.0 Pro

Input-referred Read Noise doesn't relate easily to image quality, Photographic Dynamic Range (PDR) is better for that. Input-referred Read Noise is more interesting to asto-photographers. They are ...

Since the active circuit of the pixel changes I would argue that dual conversion gain sensors have two base ISO settings.
