I had a 139 for a brief period. It was an OK camera, I've owned worse and I've owned better. It was small and light, which was nice, but the camera's covering peeled off in an alarming manner (actually it just crumbled into flaking pieces). I could have lived w/ that, but the shutter was a little loud, and I wasn't a big fan of the viewfinder. In the end, I preferred Leica R glass to Zeiss, so I sold it. No regrets. I still think R glass is just about as good as it gets in photography, and the Leicaflex Standard I bought is built to an amazingly high standard.
