That is what you get for using an APS-C circular fisheye lens on an APS-H size sensor camera <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='' />

Actually 1Ds3 <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' /> I've also tried the Sigma 8-12 DC on the 5D2... very sharp right up to the hard vignetting borders outside the intended/APS-C image circle!

It's the only circular fisheye available for ASP-C (at least, as far as I know), so there is not much of a choice if you want to get all-sky images. The only question is: Is it worth the money?
