Pippoz Offline Upload & Sell: Off p.1 #1 · 800mm Contest: Nikon or Canon? For 1Ds Mk II: Nikkor ED 800mm f 5.6 with adapter ring or Canon FD 800mm f5.6 L with original 1.26X FD-Eos convertes? Any pics/review of the two guns? Thank You Pippoz Jun 04, 2007 at 01:43 PM

kgelner Offline Upload & Sell: Off p.1 #2 · 800mm Contest: Nikon or Canon? If you're thinking along those lines, why not the Sigma 300-800mm f4.5-f5.6? More flexibility, and a really sharp lens! Jun 04, 2007 at 04:54 PM

HerbChong Offline Dedicated FM Upload & Sell: On p.1 #3 · 800mm Contest: Nikon or Canon? the Sigma isn't a variable aperture lens. it's a constant f5.6. the Sigma 800/5.6 prime is better than the 300-800 zoom and is not as sharp as my Nikkor 600/4 AFS-II with the Nikkor TC-E14II extender. the 800/5.6 is slower than the Nikkor to focus too. i ended up selling my Sigma 800/5.6 after testing the two side by side.

Leethal Offline Upload & Sell: Off p.1 #4 · 800mm Contest: Nikon or Canon? Sorry Herb, the Sigma is definitely a variable aperture! A very sharp lens too, from what I have read! http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3308&navigator=3 Minimum Aperture = F32 Maybe you were thinking of one of their catadioptric lenses...

Herb means the Sigma 300-800mm maximum aperture is a constant f5.6 at all focals, not f4.5-5.6 as Kendall says. Ramón Jun 04, 2007 at 06:57 PM

ambystoma Offline Account Locked p.1 #8 · 800mm Contest: Nikon or Canon? For what it is worth. In my film days I simultaneously owned both the Canon 800mm F5.6L and the Nikon 800mm F5.6 ED. I originally owned the Canon because it was the only 800mm F5.6 lens available as the nikon 800mm F5.6 came along several years later. I thought the canon was good but when I did side by side film tests the nikon was the clear winner. It wasn't even close. The nikon was quite superior wide open, stopped down, at infinity, at the closest focusing distance. The canon was lighter. And the rear knob focusing was a little easier to use. But that was about it for the canon. Image quality wise it just wasn't in the same class as the nikon. Jun 05, 2007 at 03:49 AM
