jimvanson Posted February 28, 2007 Share Posted February 28, 2007 Canon EF 70-200 mm F4L IS USM lens -- I'm looking for reviews and owners opinions of this lens. I've gone through this forum & googled my question but opinions are sparse. What I'm primarily interested in is image quality, wide open, at the long end. Thanks.

david_lau3 Posted February 28, 2007 Share Posted February 28, 2007 First published reviews: Photozone: http://www.photozone.de/8Reviews/lenses/canon_70200_4is/index.htm Pop Photo: http://www.popphoto.com/cameralenses/3855/lens-test-canon-70-200mm-f4l-ef-is-usm-af.html I also own this lens and Canon 200/f2.8. My personal test shows that the zoom equals to the prime in resolution (both centre and edge) at every aperture, including f4. The only thing is the zoom suffers from vignetting at f4 but much less in f5.6. The prime has no vignetting at f4. The zoom is also very friendly with Canon 1.4X. It is as sharp as the prime + 1.4X. The only thing is the zoom + 1.4X shows some CA (red) at extreme edge while the prime has none. Link to comment Share on other sites More sharing options...
t_n1 Posted February 28, 2007 Share Posted February 28, 2007 David, what camera are you testing the lenses on? Using a 1.6 crop camera won't show much at the edge. Link to comment Share on other sites More sharing options...
david_lau3 Posted February 28, 2007 Share Posted February 28, 2007 I test the lenses on 5D. I have tried my best to get a reliable result: camera on tripod, IS off, manual exposure and use building at a distant to minimise focus error. Link to comment Share on other sites More sharing options...

jim_larson1 Posted February 28, 2007 Share Posted February 28, 2007 I like the photozone tests. . .except that they test on a cropped camera. And the fact that their plan is to keep shopping for a 70-200/2.8L until they get one that they like (Are they up to three?) Link to comment Share on other sites More sharing options...
mars c Posted February 28, 2007 Share Posted February 28, 2007 Nice and helpful test , David,<p> I see more CA with the zoom, though the sharpness between the 2 lens is about the same.<p> There is also a sample shots of that lens I found on the net.<a href="http://www.pbase.com/lightrules/73v72f4is" >hyperlink</a> Link to comment Share on other sites More sharing options...
alexdi Posted February 28, 2007 Share Posted February 28, 2007 I consider the 70-200/4 IS the best zoom lens in that range by any manufacturer. If it's not good enough for you, nothing else will be. Fortunately, it just so happens to be superlative. DI Link to comment Share on other sites More sharing options...
