Vignetting and magenta cast aside, even at f/8 we aren\'t seeing the corners *or* edges clean up. To some degree I see the same repeated even on the 5N with the ZM 25/2.8 although the edges do become acceptable enough when stopped down. On the GXR in contrast the edges and corners look great by f/4 and just get better - I get the sense that I am seeing the real performance of the lens, at all apertures. That missing AA filter is accounting for more than just improved resolution it seems.
Poor Rob was pilloried for doing his work, even though he applied what appeared to be a consistent methodology (focus on a single spot for all lenses, manly tripod, etc.) yet his work gave us the heads up and queasy feeling that at least some lens designs - notably the wider Zeiss - were going to be problematic on the NEX-7. In reality he gave us the first useful heads up.
To some extent I\'m guilty of hoping for a better result against the mounting evidence regarding the NEX-7. I recall seeing Rob\'s shots (and the 21 and the 25 and to a lesser extent the 35) and feeling my stomach churn inside because I *so* wanted the NEX-7 to work out with rangefinder wides, not that I was all that attached to Sony but I wanted a camera with a built in EVF.
It turns out firmer edges and corners are more important to me than a built in EVF which principal additional benefit is easier sliding the camera in and out of my bag, and it seems that my bag has learned to accommodate a camera with an external EVF.
