You do see more resolution from it when you are using 36 MP FF sensor (compare to 21 MP FF Canon) ? This is what my experience too, when using 18 MP APSC. I compare it with APSC crop from 5DII (21 MP --> 8 MP). The result is 18 MP APSC has more resolution. The lens is support that density, at least in the center of the lens. Can't say for the corner of the lens, since my 7D is using only the center of it.My anecdotal experience suggests that most Canon L lenses have plenty of room re resolution.

Then I imagine they'd not care about FF vs crop, either.True - but perhaps the fact that outside of this forum very few actually care too much about that does?...if future advances in ADC performance does not partially explain why Canon isn't busting a gut at the moment to compete with 'only' 14 stops of DR at base ISO.
My post was a sharing moment with all dpr fellows and not a threat to Canon. Sorry, for that there must be a complain department at Canon Inc.Hmm. I guess threatening to leave might make you feel better for a while, but whether eventually you do or not but that'll be the total impact it'll have. Sorry.I don't know if an exodus out of Canon is coming but if they doesn't come with a breakthough sensor after Photokina, I will start my migration to Sony or Pentax Z....if future advances in ADC performance does not partially explain why Canon isn't busting a gut at the moment to compete with 'only' 14 stops of DR at base ISO.
Of course 36mp > 21mp to have more resolution. Of course your 7D will resolve more if you shoot from the same distance and unable to move closer such as in moon shot than your 5D2.You do see more resolution from it when you are using 36 MP FF sensor (compare to 21 MP FF Canon) ?

True.Of course 36mp > 21mp to have more resolution.
NOthat could maximize 50 MP in FF, so it will have the same resolution as the 50 MP MF with its lens ?
YESOr is it just too difficult (impossible) to make a such lens that sharp ?
YES. Resolution of the lens and pixel density of the sensor go hand in hand. If you have a small sensor with a big number of pixels (50mp as you suggest) thanSo the only way at the moment is just to make the sensor larger, thus less stretch for the lens ?
But it has. The maximum sharpness (and so the resolution) of a lens is achieved at 1-2 stops down from it's maximum aperture. So if you have let's take for example an 50mm f1.4 than to use the maximum resolution of the lens you would have to shoot at f2. And then you have a very shallow depth of field. That is why we say that you have DOF control actually, not because you cannot achieve the DOF you want. FF can achieve shallower DOF than APSC or MFT. But in order to achieve maximum sharpness you need to shoot at a wide aperture and so you have a very shallow depth of field.I could understand if smaller format (such APSC or mFT) will have another problem, DOF control problem, even if someone could make a lens sooo sharp for them.
But there is no DOF control problem in 35mm FF, is there ?
Maybe just resolution problem in wider aperture ? in f/2 perhaps ? But not resolution in f/2.8 ?
Some one who know these, please chime in ...
Thanks

The actual, aka, perceptual resolution is less than sensor resolution affected by many factors, sensor crop format, lens...larger sensor format, better lens, less loss in resolution.True.Of course 36mp > 21mp to have more resolution.
I don't know if there such a worst lens that isn't worth to use it above 5DII's pixel density.
If such a lens is exist, then it's little (or zero) benefit to use 36 MP sensor over the 21 MP one.
So I think max resolution is a combination between sensor resolution and lens resolution.
Belong to areas of better techniques.Of course other factors could affect the resolution : camera shake, focus, diffraction, etc.
Yes for those Facebook and regular family photos.Though 12 MP is already plenty for most application (or situation), for most people.
Thanks. At this moment 12mp is not enough for me. 22mp is OK as I only have 2650x1440 resolution monitor at this moment, but 36mp is ideal when I own a 4K monitor as usually 50% of crop has the best displaying quality. When one day there is a 8K monitor, then even 36mp is not enough and want a 54mp then.I am using G1X (not the mark II) myself, and I believe its max resolution is less than 12 MP.
But I know that you are not in the most people category,
and that's a compliment, Peter.
Not really for resolution but for UWA and pano purposes. There is no lens can record such wide angle near 180 degree with reasonable resolution and virtually without distortion. I have lots of pano photos to be processed in my recent central EU trip.I know that you are stitching, I consider you are not satisfy with current camera's resolution can give you, at least not in one shot picture.
