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,

Unlike the very nice photos you show above, your previous photos had important elements of the scene outside the DOF and were shot with that shallow DOF because the lens used did not have IS.

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.

You'll have to start another thread (preferably in Open Talk or the PST Forum) about in-body IS vs in-lens IS.

2) No need to shoot at equivalent DOF of crop camera, or theoretical DOF on paper that is the key.

Well, yeah, you really do if you can't get what you want in the DOF when shooting wide open.

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.

Depends on the scene, of course.  I've taken pics where the entire scene would be within the DOF at f/1.2, and I've taken pics of scenes where even f/11 didn't cover it.

You see in even such deep churches with even F3.2 and F4.0 the edges are still sharp.

Depends on the lens and focal length, of course.  For sure, the 35 / 2 IS will perform wonderfully here.

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" ...

In the case of the 35 / 2 IS on FF vs the 17 / 1.8 on mFT, sure.  It would even be true for a hypothetical 22 / 1.2 for crop.

The Canon 35 / 2 IS is a stellar lens.  Here's to hoping that the 50 / 1.8 IS (preferably 50 / 1.4 IS) is every bit as good, if not better, and is closely followed by an 85 / 1.8 IS.
