Today, at a visit at the local photo dealer, I had an early Leica M4-2 camera in my hands. The camera is realy beautifull, no scratches and almost no signs of wear. Days before, I read some bloggs and forum comments on this type of camera and the general consensus is, that early models should be avoided. The viewfinder is clear but the shutter seemed not to work correctly at 1/8 s (shutter was to fast without the specific noise for shutter times below 1/30s). The vendor told me that it was recently cleaned and adjusted (CLA), so I wonder why this problem arrises. Has anyone made bad experiences with early M4-2?
