Ultimate image quality or just the best you can realistically afford and are willing to carry? I would have thought ultimate image quality still comes from digital formats much larger than FF (not that I can afford to find out either!).
Sorry, I wasn't meaning to imply that I have ultimate image quality, simply that that wasn't the issue - lost a bit in pre-posting edits.

Do you have or know of any images where this can be demonstrated clearly? I understand the theory about aperture values on full frame allowing for finer control and shallower DoF but when it comes to differential focus am not sure it's all that clear cut if you take into account the "telephoto effect" smaller formats have.
I can accept FF is better for shallow DoF but I'd need to see proof to accept that you're better off with FF for differential focus (i.e., sharp subject against a blurry background) to accept it as a practical advantage. APS-C (and I assume 4/3rds) is far more capable of differential focus than a compact!
If you're using the same lens on different formats, then there's no advantage. However, in practice you use a greater focal length lens on full-frame than with a smaller format to get the same angle of view. I can't track anything down right now, but there is quite a diffence between a 50mm f1.4 on APS-C and an 85mm f1.4 on full-frame, for instance - I'll try and get round to posting some examples.
