The distance depends on the FOV, not on the format. Equivalent FL = same FOV = same distance to the same target.

Note that I am talking about equivalent lenses, not about the same lens.

We were discussing resolution. To compare resolution across different sensor formats accurately...you have to maintain the same distance to target or your resolution results will not be comparable.

When you shoot with equivalent FL's, you do shoot from the same distance.

Yes...for example... 40mm f/4 1/100 ISO 200 on 4/3 is equivalent to 50mm f/5 1/100 ISO 320 on 1.6x which is equivalent to 80mm f/8 1/100 ISO 800 on FF when the photos of the same scene are taken from the same position and displayed at the same size.

Not sure our friends at DxO are so picky

BTW, even if you don't, the results will be comparable.

Not when comparing resolution across different formats.
