So I'm testing a Leica M4-P, a camera borrowed from a generous fellow photographer. The camera is as it should be - used and wonderful. I'll hand it to us Leica lovers: It is a marvel to use; a symphony in mechanical perfection, ease of handling, and precision. My rational side says I don't need one. The other, not so rational, side to me screams I must have this camera, or another one like it. Why do I want it so bad, when all I am really interested in (rationally) is the print and its quality? Prints from either look remarkably similar at moderate enlargements of about 6x8 and 9x12. Some negatives cropped to using about 1/2 the negative area at those print sizes.
