I have a wide range of Zorkis and Feds, a Canon L, and a Bessa R. From a shooting standpoint, there is no contest. The Bessa has a brighter clearer viewfinder with multiple sets of framelines and a built in meter. The Canon has multiple magnifications, but no framelines, and the rangefinder is closer in brightness to a Zorki than a Bessa. Is the Bessa as sturdy as a Leica? No, but if you are going in harm's way, carry the Zorki. But if you are really strapped for cash, why not keep using the Zorki? It is certainly competitive in usability with any LTM rangefinder except the later Canons and the Bessa. $400 will buy a lot of film.
