The Fuji is quiet a bit larger. Also the 24Mpix sensor of the fuji somewhat makes up for the difference in crop factor.


It would be interesting to know how much effective resolution the diffraction limit robs. The new 20Mpix mft sensors surely will suffer more in this regard.

 

Hi Chris,

 

That is a misconception, really. Resolution of sensors do not even come close to diffraction limits, in any way, while good lenses at their optimum apertures do. And as effective or system resolution always is a combination of both sensor and lens resolution, and the total system resolution is always determined by both with the final system resolution by definition always being lower than the lowest of the two. Only until you get to the diffraction limit for a sensor with the diffraction limit of a lens, the sensor will "outresolve" a lens.

 

Considering we are talking 400 lp/mm and more for F/4 and F/5.6 lenses here, and a little less for smaller apertures, we still have a long way to go, if we even ever reach this point, as the small number of photons collected for sensors with that high of a resolution will generate too much noise to resolve anything from a practical POV.

 

I can set up a little table if you like, to show the effects, and include a 16MP and 20MP MFT sensor besides a FF and/or APS-C sensor. Just say so, and I'll gladly create such a table .

 

Kind regards, Wim
