I had a small asignment yesterday shooting a kid. Most of the pics were shot digitally with Nikon SLR gear but I also shot a roll of Reala with my M7.
I got the roll processed today at the lab. The strange thing was that the M7 had missed frames! Some there were pictures on and some not. So I had pictures on frame no. 2, 4-5, 7, 9-14, 16-18, 20-21, 25-27 and 34. The rest of them were blank!

So from a 36 exp. roll I got 19 frames.
Have anyone had this problem? do you know what can be wrong or what I may have done wrong?
