Not so far as I've read this evening.

Update:  DAG emailed me that the 50 DR lens head will not fit the Rigid 
Summicron focusing mount.  He can cut off the close-focus cam to make the 
DR work on the M8.  That sounds rather, uh, irreversable.  Kind of like a 
vasectomy.  :-)  Not sure I want to do that.

Which makes my interest in a 40mm to 39mm step-down ring even keener.  I'd 
like to try the 50/1.8 Canon, and I'd like to use it with an IR filter.  It 
has a 40mm thread.  As I mentioned earlier, a little dental floss around 
the filter threads of the IR filter would work as a stop-gap measure, but I 
wouldn't rely on it long-term, especially with a lens hood attached to the 
filter.
