Юрий, при всем уважении:
у 10D - байонет EF
у всяких разных 18-55 - EF-S
нужно пилить
Ну,тогда я в полном обалдении о Кэноновских дизайнеров!

Привожу мнение одного из самых известных западных фотодеятелей:

I'm guessing that the mirror on the 10D is small, like the mirror on the 300D. It certainly looks much smaller than the mirror on my EOS film bodies. Whether it's larger than the 300D mirror I don't know since I don't have a 300D to compare it with, but my guess is it's the same size. The whole mirror/shutter/sensor assembly is probaly the same as in the 10D. That would make sense from an economic point of view. Less parts to mess with.
The reason why Canon didn't make the 18-55 fit the 10D is obvious. If it fit the 10D it would also fit the EOS-3, the EOS-1V and all the other bodies with large mirrors. Users with small brains would no doubt "try it just to see if it worked" and slam the mirror into the back of the lens. So Canon idiot proofed the system. Even it it would have been fine on the 10D, they couldn't take the risk of someone putting it on something else. "
