Guy from
>>2954237 here. I did some tests again.
I compared Nikon D80 to Canon EOS M again. Sensor inside the M is the oldest CMOS you can find in new cameras (EOS M10 and 1200D/T5 have the same one). Any other modern CMOS DSLR and Mirrorless can only be better than EOS M results i will present.
On EOS M i used Helios 44-2 58mm f/2.
On D80 i used Helios 44M-4 58mm f/2.
Exposure, white balance and aperture are the same. I converted the RAWs in IrfanView because surprisingly it gave better results for CCD then Lightroom.
