Problem with the Canon's is the 34mm filter size. The Leica's take E39 either directly or with the Leica push on adapter. I already have E39 IR/Cut filters and the little E39 screw on hood made for the 50/2.8 (which I also already have) that would work for a E39 35mm on the M8.

Adapting the lens and buying additional filters, etc,. starts to make the cost a lot more. Just an IR/cut filter is adding about a third the price of the lens, then if you need a custom 34 to 39 adapter...
