Which Leica M lens acts as a medium-angle zoom? It's the Tri-Emar, mate, and Mike is very matey with it. Here's a review from Macfilos of five years ago...
The Pixii rangefinder with M-mount is launched today. It's an APS-C compack with no screen, no external storage and a reliance on smartphone connectivity. M users will be intrigued but will find the lack of removable storage worrying.
Judging by the rapid-fire arrival of M-mount lenses, you'd think Leica's cameras were the best-sellers. But no, the secret of the success of the M system lies in simplicity, mechanical excellence and the resulting longevity.
