dreilly is correct that the 7 is a fantastic buy in today's LTM market. I've had one for a couple of years now, and agree that the vf is outstanding, only slightly inferior to that of an M4, which is its most direct competitor (although in terms of size, it's the M5). As a glasses wearer, I like being able to see the 35mm framelines easily, which I can't do on a Canon P. The 7's vf can also serve in a pinch for 28mm, although the lower magnification vfs in Bessas are better in that regard. The meter on my 7 is working just fine in daylight conditions. And there's no question that this is a solid, well-built camera body that is equal to anything Leica produced at the time (the 1960s).
I find the 7 to be especially useable and well-balanced w/ some of the larger CV lenses, like the 35mm Ultron. That's a very good shooting combo, if you don't need light weight.
Which brings me to the downside of the 7: it's a heavy camera, not pocketable really. Put an old Canon chrome lens on it, and the combination will weigh over two pounds. I don't have particularly large hands, so the size factor of the 7 is not an advantage to me. From my standpoint, the size and weight of the body is a limitation on its use as a camera for travel (although I've carried it on hikes in the mountains where I appreciated its robust construction and ability to frame precisely). For that reason, I'm thinking about putting mine up for sale. As an around-town shooter, though, it has a lot going for it.
