thanks for the feedback.
The fight is from a sequence I got of about 4 frames - the build up and one after the one posted. Then the battery ran out!
The Canon was a super lens for backlit sunlight - as Sean and others have pointed out. However, it's now been traded for a 40mm Rokkor, so I'll post some of those next.
I love the R-D1 for b/w - I think it's (dare I say it?) more 'film-like' than any samples I've seen from the M8 - except perhaps for J. Borger's work, which is always superb...
BTW, I hope it's not too up myself to point to gallery pix here?
