Leica aficionados argue adamantly that the M3 is the best Leica ever made. Difficult to disagree with an assessment like this, as it is not only a precision made instrument, but one that is built to last for generations. Made from brass with chrome plating, the M3 feels like a solid chunk of metal. It is heavy in the hand, but strangely comfortably so (approximately 680g). Everything is perfectly smooth, precise, and quiet, not unlike a Swiss watch. Manual focusing is fast and accurate with a rangefinder patch that is bright, contrasty, and much easier to use than the fuzzy ball of a patch that similar vintage Canon and Nikon rangefinders used. The viewfinder magnification is a glorious 0.91x, which makes it perfect for fast 50mm lenses such as the Leica Noctilux 50mm f1.0 and Summilux f1.4. However, like many precision instruments, Leica rangefinders need to be adjusted every once in awhile, not an inexpensive proposition. In fact everything about Leica runs from expensive to prohibitively expensive to absurd. The two M3s that I had did not have any trouble with rangefinder accuracy, but the top speeds of 1/1000 and 1/500 were more like 1/250, even after the cameras were cleaned and lubricated. This in effect made it difficult to use fast lenses with the slowed down top speeds. Hard to find bargains these days as the M3 is very sought after by street photographers and Cartier-Bresson wannabes. There is no doubt that you can still take great photographs with an M3, but you can with many other cameras as well. It seems to me that these old Leica cameras, and especially the M3, have become fetish items, worshiped more for their remarkable craftsmanship and the way they feel and sound, than for any photographic advantages they have over the hundreds of other cameras you can choose from. Nevertheless, rationality cannot compete with a fetish, it is better to get a M3, use it, and then get over it (or not). In all likelihood you will probably be able to sell it for more than you paid for it, so it will be a truly profitable experience. Purchase Leica M3 here.
