Deconvolution sharpening and AI have easily added two stops to the diffraction limit in modern tools that offer this tech. But to your point, you wouldn't notice anything without those technologies until f/11 although the scientific number would be more like f/5.6.Wildflower-nut wrote:diffraction limited at F?
32.5 x 1.6 x 1.6 = 83.2 = YES!Neilyb wrote:So would this be the full frame version of the 90D sensor?
I did not do the math but it sounded right. I do wonder, based on the fact their best ever sensor is only 30MP and their 50MP sensor was completely uselss, why they would do that?E.J. Peiker wrote:32.5 x 1.6 x 1.6 = 83.2 = YES!Neilyb wrote:So would this be the full frame version of the 90D sensor?
Those sensors were based on the same process technology that Canon used in 2008. This is a clear indication that they have finally launched a new generation of process technology. If it catches up with some of the others then it likely will be better than their 50mp sensor. It has become pretty clear that Canon shooters tend to not obsess about dynamic range as much as virtually all others so as long as they can continue to squeak out 10 stops of dynamic range (real world not engineering - see http://www.photonstophotos.net/Charts/PDR.htm and select the 5DSR) they will likely be OK.Neilyb wrote:I did not do the math but it sounded right.

The scientific number I think would be around 6-5.6. I'll look into the software you are speaking of. It is also nice to know there is some practical headroom to say f11.E.J.
