Hi all, this is my first post on this forum but I've been treating the Digital Picture website as holy doctrine for the last year or so, when it comes to selecting hardware.


Im looking to get a wide angle lens somewhere in the region of < £700 and am torn between the 17-40mm f4L and the 15mm fisheye


I use a Canon 5D mkII, so 15mm is gonna be very wide, also, with 21MP, cropping an image or squashing it slightly to compensate for rectillinear conversion isnt going to be a huge issue.


My question is aimed at anyone who has used the fisheye in this way...


... how much image quality is lost in this process? I would like to be able to use the fisheye as a standard ultra-wide angle (from time to time). But I want the images to still be of good enough quality to submit to high end stock sites.


I use Lightroom 3 and the lens profiles to do any lens correction


Thanks in advance for any input
