Re: A thinner sensor stack may be possible after all!

When its question of comparing the pictures taken with different cameras, it always puzzles me to no end the logic that some of you guys use. Downsizing the output of the higher Mpix. sensor to ,match the lower one is like throwing away the extra resolution of the higher camera. You could as well compare the newer 50 Mpix.Canon 5DS with a \'venerable\' 4Mpix. Canon 1D downsizing those 50mp. to 4mp. and you\'d conclude that the new Canon flagship has no visible advantage over a 13 year old 1D.
Do it the other way around and you\'ll see the real difference between a 50mp and a 4mp. sensor. The same logic applies comparing 24mp. to 36mp. sensors, etc. Always upscale the lower resolution picture to match the Mpx. count of the other. You won\'t throw away any info from the higher sensor and you can\'t add anything to the lower one, because that upscaled image will have more Mpix. but no more real resolution than the original image.
The reason for downsizing the output of the A7R_M was to be able to compare the lens performance between two cameras that have different resolutions consistently, without sensor resolution influencing the results. I don\'t have a modified A7 which matches the Leica M240 resolution.
This is not a \"my Sony 36Mp camera is better than your Leica 24Mp camera\" type comparison.
Upscaled versions of the same test can be downloaded here which proves that 24Mp upscaled to 36Mp is always going to be inferior in resolution but introduces another variable which I dont think is helpful
