ef-s adaptor?
 

I have an ef-s 60mm macro 2.8 lens and love the sharpness and bokeh that it produces and am wondering if there is an adaptor that would enable me to use this lens on my 5dmkii. The calumet guy says canon extenders can only be used on 135mm and upwards, so is there any other way I can get to see what this camera can do with this lens?

The issue with fitting an EF-S lens on a 5DII as I am sure you are aware is that the EF-S mount projects back into the camera body more than an EF lens & the mirror will foul on that projection. So you will be OK with an extension tube. I just tried an EF-S 18-55mm F3.5-5.6 II with an EF12 II extension tube & it works great with auto-focus etc.

Alternatively for a more permanent conversion see MetkuMods - Because you love your hardware!

BTW The equivalent proper EF lens is the 100mm F2.8 USM Macro is a cracking lens. I bought my wife one for her birthday in April & she has hardly had it off her 5DII since:-)

Thanks Nigel, that is good to know- your wife's pics are exactly what I am looking to use this lens for- close-ups of teeny critters and flowers! I have been using my 70-200 2.8L IS but I can't fill the frame, so the extension tube is my next purchase. Thanks again, Bill.
