You ever shoot any film? You remind me of a friend I have. He's constantly on the phone to me comparing results from cameras. He calls me with two images on his PC display, side by side, each blown up to 8000% (btw that's a joke) and he's telling me that camera Y is marginally better than camera X because of [unknown argument deleted]. He tells me all the scientific technical stuff, and I'm like fitting the noose around my neck getting ready, and he ends up by asking me in desperation which one he should get. I don't know how many times he's swapped and changed gear. If he ever made it to a photographic gallery they'd be wiping nose-marks off the prints, bless him. Adam, I don't think we're in the same wormhole mate. Good luck with your edge performance ;-) > >Another example, this one on a EOS 3, with the EF 28-105 f3.5-4.5 USM II >wide open at 28mm on Acros 100: > >http://www.flickr.com/photo_zoom.gne?id=85917538&size=l It's asking me to join FuckR and there is more chance of me dining with Elvis. > >This shows off distortion that would be out of the frame on a 1.6 crop >camera and possibly on a 1.3 crop camera.

The 28-105 is pretty comparable performance-wise >to the 28-135, it just lacks IS and the extra length on the tele end. I don't use such lenses and have no intention to.
