24 mp (A7) vs. 32 mp (A7R) vs. 16 mp (E-M1)

Since this got lost as the second last post of a now closed thread I post these here again for possible discussion:

Here are some comparisons at "equivalent" ISO, meaning that for equivalent DOF and exposure time you need to use 2 stops higher ISO on full-frame cameras, unless light and in-frame motion allows to use a slower shutter speed on FF. Unfortunately the DPR studio scenes used the same aperture for all three cameras, still we get an idea of how resolution compares - and how the resampling algorithm very much affects the outcome - with the type of content presented. All images at 32 mp, which means that the A7 and E-M1 images have been upsampled to match the A7R image size.

When you compare these you might have to use the "View Original" button, because DPR's own 100% view still uses a recompressed JPG of lower quality!
