Summary: Great to have and attach all your favourite ef lenses to the EOS M. It pretty much came as a freebie due to the promotion running with the EOS M I purchased at the time, so absolutely perfect :)
Summary: EOS-M Mount AdpatorI had this item with the EOS-M camera kit bundle. I don't yet have any EF-S lenses, but with a bit of forward thinking and the fact that this is well over £100 on its own, I was happy to have it in the bundle. It is clearly well made and of the usual Canon quality.
Summary: Came free with my EOS M but I would have bought one anyway, works well, although some cheaper lenses don't interface well with the M making them quite noisy, worst one I've tried was my 50mm 1.4, changing the focus settings improves things but sounds rough. The tripod mount is removable. Nicely made and it was free!
Pros: Durable, Easily Interchangeable, Lightweight, Rugged, Strong Construction
