yeah me neither. I went to the camera shop asking about it but the guy seemed pretty clueless about it...told me it'd work on a 10d/20d/30d/300d/350d/400d but when I asked him about putting it on a 1d3 he said "uhhhh, sure....why not?" Well the answer to his why not was that I didn't want to trash my lovely 1d3, so i left without trying it.
maybe i'll have to go back there to play with it, and just push the kid out of the way when he tries to help.
too bad it doesn't also work on the 5d...that'd be downright amazing.
FYI: it does work on a 5D too! FF, it'll have a 180 degree AoV diagonally from about 15 mm.
Panorama and VR shooters use this lens on any dslr. Although the image circle was designed for APS-C, the mount is just a full-size EF mount, and the lens element at the back won't touch the mirror. When zooming you just increase the size of the image circle, which is why it still works as a proper 180 degree diagonal fisheye on APS-H and FF, provided you use it at the appropriate FL setting, where the (fixed) lens hood just doesn't vignet anymore. So 12 mm on a 1D Mk III, 12-13 mm on a 1D Mk II, and 15 mm on a 5D or 1Ds.
And for an even wider AoV on APS-H and FF, you can actually shave the lens hood, which will give you 194 degrees AoV on FF, and it loosk like 185 or so on APS-H.
Kind regards, Wim
