Re: Wide Angle: How picky should I be?

Victorian Squid,

Thank you very much for taking the time so answer with so much detail, and share those comparison photos. I downloaded all the originals and the 17-40mm is definitely soft in the corners at f4. 100% isn't even necessary to see it at that aperture.  I found a nice review comparing the 17-40 at 21mm, the Zeiss 21mm 2.8 (and the Nikon 17-35mm 2.8 @ 21mm). On the fourth page (linked below), smaller apertures are compared, and predictably the difference in sharpness diminishes greatly (small samples though).

My point being I guess that as long as I have some range at all at which I can get really nice sharpness across the frame for those times where I'm shooting very deliberately on a tripod, maybe I can live with the rest (until I can't!).
