I'm gradually compiling my archive of lens tests (http://www.16-9.net/lens_tests) on the 1Ds and 1Ds II, doing the kind of Olympus v Zeiss v Canon tests that are hard to find elsewhere, with particular attention to wide angles in the 17-24mm range.
Your tests and contributions are welcome.
There is also an up to date list of EOS adaptor sources and compatibility information (http://www.16-9.net/lens_tests/compatible.html).
And who would have thought after three years of testing that the last lens standing would be a Nikon zoom? Is my AFS 17-35mm really as good as a Leica 19? I can't quite believe how good this one is myself. Please tell me if I'm doing something wrong!

Some interesting tests. Keep them coming.
A bit worrying about the 17-40.
I notice you ranked the 16-35 slightly above the 17-40. Although the 16-35 MTF plots show it to be quite a bit less sharp at f8 than the 17-40.
Have you tried more than one 17-40?
Could you also add a methodology page to we can understand what you are doing better.

Thanks Lester: most of the pages say something about test conditions in the small print. Most of the results are based on single sample tests, but where I have owned or tested more than one, I have adjusted the ratings accordingly to average out the samples. In the case of the Canon 17-40mm, I've used three samples, and all of them were worse than my Sigma 15-30mm (http://www.16-9.net/lens_tests) from 17-28mm. Testing them one at a time is a tricky business (http://www.bizgiftdirect.co.uk), but running multiple sample tests is a nightmare!

New tests (http://www.16-9.net/lens_tests) now online: just added the Leica 21-35 v Zeiss 21mm f2.8 test, and the one I shot last week, comparing the Zeiss 18mm f4 with the Nikon AFS 17-35mm f2.8 - how insanely great is this lens??

Mark: thanks for sharing your tests. I find them interesting and valuable. Very kind of you to share all of your hard work.
Best regards

Very interesting tests. Thanks for sharing with us. I know people go on and on about the Zeiss 21mm, but it is extremely impressive!
If you get a chance to compare some of these lenses to the Canon 16-35 (my current WA lens) I would be very interested to see how they compare.

Just now I've updated the site with a group test of the Canon 16-35mm f2.8 v Olympus 18mm v Contax Zeiss 18mm (http://www.16-9.net/lens_tests)
The results make interesting viewing.
If I owned a 16-35mm L, I would take this as good news, though: better quality is available for relatively modest outlay.
And yes, the Zeiss 21mm is very special: still not hyped beyond its ability!
If you find the tests useful, please remember that the site is financed by the honour system (good old Google!) I can't abide the increasing numbers of photography sites that charge to view their tests.
