Hey James,
finally got the time to read both your review of the M9 and of the Pen E-P2 and I really enjoyed them both. I used to use a Leica M-3 as my photo-journalistic camera in the 1970's and I loved it. There is something unique to the rangefinder experience and I found it particularly good for the type of shooting you encounter in journalism. I can see where both of these cameras would adapt well to the type of shooting you experienced on vacation.

In my "day job", however, I doubt if either camera would meet my needs. I can't imagine shooting dog shows or events with a rangefinder or a camera with no real viewfinder. Nor is that what these cameras were designed to do. I might think about using the M9 in certain wedding situations, however. Not as the only camera but as the "candid" camera, I think it would work like the old Leicas did in journalism.

Thanks for the reviews and for sharing your images of Yellowstone. I really enjoyed both.

Jim
