Just wondering if anyone has tried hacking the Canon 60mm EF-s Macro to allow it to be used on a 1Ds or 5D style camera? I know the rear shroud on the 10-22 EF-s can be removed easily ( just set the lens at 22mm, insert your finger and lift it off ) to allow the lens to mount on a FF camera. Inspecting a 60mm macro at a camera store reciently, the rear shroud looks to be similar, but I was not about to try disassembling it at the store!

Common sense would seem to be that if the 60mm macro would cover Full Frame, Canon would have released the lens as a EF and not an EF-s lens. I have read that the 60mm macro is quite good in resolution and contrast, and I like the fact that it does not extend while focusing. I doubt that I would replace my Leica 60mm Macro with this lens, but just wondered if the rear shroud is easily removed for testing on a FF camera?

Taking a look at my 60mm macro, I doubt it would work very well, if at all. While the front element of the lens doesn't move on focus, the rear element does move quite a bit. Towards the ends of the focus path, the rear element goes out to the shroud...if you focused to infinity or 1:1, you'd have mirror clearance issues. Maybe it would work with an extension tube, but then you'd definitely lose infinity focus.

Also, from what I understand, the 10-22 only works on full-frame from 17mm to 22mm. On a prime, you don't have that sort of leeway

If you want to use this lens on FF for macro work, just use an extension tube. The newer Kenko extension tubes can be used also with EF-S lenses. You lose infinity focus as stated above, but you won't need it for macro work anyway.

What about vignetting?

Looks like an older thread with no images. Can someone post newer ones?

Can you see them here?

That is one sweet lens, the EF-S 60mm. Crazy MTF chart for it.
I'll give it a try and post some shots too. Great idea!
