Not sure why but i think the images from the canon look nicer than the sigma. Did you feel the same way ?



Or maybe it is not fair to compare the two lenses given that they are not exactly the same.

I'm impressed. With this lens and the 17/4 TS Canon made two benchmarks WRT both novelty and optical excellence in the UWA arena, something it did not fare so well in the past.



Now, about that 16-35/2.8 Mk III.....

Hi Klaus,



Did you test the lens on an APS-C camera as well?

Personally I own a 5DmkII and a 60D as well and like you said with the 5DmkII I am using the EF 8-15 4.0L almost without exception at 8mm or 15mm. On the 60D things are a bit different, here it is used as a ultra-wide to lineair fisheye lens (from 15mm to 10mm) which is also fun to use. For owners of both FF and APS-C EOS cameras this lens is quite a gem.



Best regards,





Rob

No, sorry. I think it's a bit pointless on APS-C because you are loosing the circular fisheye "mode". That's the prime value proposition in my humble opinion.

For a test of this lens on both FF and APS-C, read the Lenstip.com review. They also put it on the EOS 50D (and it performs well on APS-C too).

Or simply consider the Tokina 10-17mm DX for a fraction of the costs, size and weight.

Frankly a zoom is also not needed if you stick to a full frame fisheye so the Samyang 8mm f/3.5 Fisheye for a few bucks and it's really a good lens.

Ok,



I will sell the lens because of the limited usage on my eos 60D <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />

No offense intended - it just feels like an overkill to me. Have fun with the lens - it is certainly the best there is.
