Certainly very useful to me particularly in indoor low-light hand-held

3000-pixel wide. Notre-Dame Basilica of Montréal

Cathedral-Basilica of Notre-Dame de Québec

GB: Do you still remember you sent me a link from someone took the same shot in Basilica of Montréal a while ago from mFT with 20mm/1.7 prime (that photo looks pretty noise) in our discussion/debate of DOF advantage from crop sensor vs FF. My experiences and photos above show,

1) with 'IS' lens, the IBIS advantage in Olympus mFT vapors and 'IS' actually is more effective and I can push to even 1/4 sec with a few tries but 5D3 high ISO is good enough and 1/8 or 1/10 is pretty guaranteed to get pixel-level sharpness.

2) No need to shoot at equivalent DOF of crop camera, or theoretical DOF on paper that is the key. My experience tells me usually by just stopping down just one stop in aperture, in most cases, you will not see much difference in looked DOF. You see in even such deep churches with even F3.2 and F4.0 the edges are still sharp. No mention at F3.2 or F4.0 FF lenses usually are sharper than crop lenses not only in center but in edges at either the same or eq aperture. In short, FF cameras absolutely enjoy IQ over crop and you don't need to shoot at theoretical DOF. Otherwise APS-C/mFT has to shoot at eq DOF of 1", eq DOF of 1/2.3" ...
