M6 ii

[Joel Eade]

I see better detail in the 5DIV image at 10 ft than I do the M6 II at 16 ft. From my standpoint, I would say the resolving power is somewhere between 14 and 15 ft, or 1.4x to 1.5x being the "true" crop factor for the sensor on the M6 II. This is the same conclusion I reached looking at other crops. So, in my mind, I am just going to call it 1.45x. Still more resolving power than a 1.4x TC (which is actually 1.36x and does also put more glass between sensor and the subject).

Very interesting .... I thought of crop factor mostly as changing the field of view and not in terms of resolution. In that regard the M6II image from 16 ft looks to have similar field of view as the 5DMKIV at 10 ft thus the 1.6 factor. It does, of course get more pixels on target from a greater distance too assuming the crop sensor has smaller pixels or higher pixel density.
