Or... even better with the His Holiness, the 200 f/2 IS @ f/2 on the Nex-5:

Hard to believe that the photo you show was taken WIDE OPEN AT F2 at 200MM...will that lens take a tripod mount?
I do not share your pessimism about the Nex AA filter, because my raw images taken with apochromatic lenses such as the Tokina 70-210 SD II zoom at 70mm/F8 and smaller show single-pixel-width features. Don't see how it could get any better. Or put another way, it seems like the AA filter is just about right if it doesn't get in the way of single-pixel feature capture.
And the AA filter can't be super heavy because I have gotten aliasing with even the kit zoom JPEGs, at F8 and middle focal length on a tripod, looking at sweater fabric etc.
You also make an interesting point, that designers of fast lenses don't expend much energy optimizing small aperture performance. Because who would pay for a fast lens and then care about its slow apertures.
Sure would love to try the Olympus 12-60 zoom on the Nex, even if its image circle is a bit small. When will some genius figure out a 4/3rds adapter that will give us aperture control on the Nex?

Quote:Being a proud owner of a Nex-5 and using it almost exclusively (instead of my 5D2, 50D, etc.), I still have to say that Canon APS-C sensors have more pixel-level resolution. Sony (and Nikon) are very well known for performing noise reduction before the data is written as RAW and this takes a toll on high frequency data (a fancy way to say fine details).
