Re: EOS 5D vs EOS 1Ds Corner Light fall-off comparison
There is some truth to that reputation (which is odd, the large throat size of the EF mount and shorter register should allow for better better performance than is achieved by Nikon, Olympus, Carl Zeiss and Leica). The real issue is the poor edge sharpness on FF bodies of the Canon lenses that go wider than 24mm (Canon's 24mm's are quite good). This is especially noticable with the 17-40L and the 20mm f2.8, which are superb performers on the cropped bodies. Oddly, the sole exception to this is the EF-S 10-22, which has some distorion issues (odd mustache distortion at the wide end), but is a superb performer otherwise. I personally shoot some Canon film kit, but mostly as a platform for M42 lenses (And Leica R soon, I recently acquired an R-EOS adaptor) and the only Canon lens I currently own is the plastic fantastic 50mm f1.8 II (Great lens for the money, but it's really crappy build quality). -Adam P.

Re: EOS 5D vs EOS 1Ds Corner Light fall-off comparison
I agree. But what I'd like to see is a corner vs. centre sharpness comparison, as that's the real weakness of the Canon ultra-wides. Light falloff is rather endemic, and I suspect the 1DsmII has some compensation in the microlens design (given a camera twice as costly, Canon has a little more wiggle-room for costly sensor modifications to reduce issues like this) -Adam J.

Re: EOS 5D vs EOS 1Ds Corner Light fall-off comparison
I've heard the Canon WA lenses especially WA Zooms have considerably more light falloff, (and corner softness), than most any other major manufacturer. It's not fair I know, but my only direct comparison is the Canon EF-S 18-55 which a miserable little excuse for a lens compared to my smcp FA 20-35 f4.0. (Yes I am comparing a FF lens against an APS only lens, a DA 18-55 would be a great direct comparison, but I don't have one). But who wants to be fair anyway?

RE: EOS 5D vs EOS 1Ds Corner Light fall-off comparison
Sir, I think you missed the ENTIRE point of the article, which was not there was any light falloff seen, the point was there was visible DIFFERENCES in light falloff between two different digital sensors/camaeras with the exact same lens and at the exact same test condtions ( only difference being sensors/cameras under test). jco -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Christian Sent: Thursday, December 14, 2006 10:23 AM To: Pentax-Discuss Mail List Subject: Re: EOS 5D vs EOS 1Ds Corner Light fall-off comparison Mark Roberts wrote: > P.
