Got the set up here on Flickr: http://www.flickr.com/photos/[email protected]/sets/72157638934590896/ Tested are: Tokina RMC 17mm 1:3.5 Nikkor 24mm 1:2.8 Minolta 24mm 1:2.8 Leitz Summicron-R 1:2/35 SEL24 on the NEX-7 Leitz Summicron-R 1:2/50 I'll add more relevant material as I see fit. So far just got the quickie f/8 "twig" test (I just invented this morning) and a crude wide-open BOKEH comparison of the longer lenses. Thus far, I'd say: The Tokina 17mm has some potential. (Using it for a true ultra-wide for the first time is more fun than dynamitin' fish.) The right side used to be & still is smeared - should try to remember to mentally crop that away when composing. The Nikkor seems fairly solid out to the corners. I used to feel the renderings were a bit "flat" on the NEX-7. Still seems that way, though the outdoor conditions aren't exactly vibrant. As before the Minolta is extra sharp in the middle & a bit looser toward the corners. Field curvature might be at play. The Leica 35mm did better than I was hoping. The (35mm equivalent) SEL24 seems slightly more impressive in the corners. The 'Cron is just awesome wide open and has significantly more capacity for subject isolation. The ancient 50mm Summicron (with all kinds of dust inside) is just kicking all kinds of butt.
