totally different beasts - film leica vs digi epson (voigty?)
I've seen M8 go for about 1,3k pounds so the same as epson. why would you want to choose epson over leica ? or better - why would you want to have a cropped sensor in RF body ? It's probably still amazing. what lenses does it take ?
They are totally different, but also quite similar in many ways. That's what I like about the Epson. I also use film cameras so can see the advantage of both systems, and the Epson (or indeed a Leica M8, 8.2, 9) let me use a rangefinder (which I find more to my liking) and digital (which I don't want to get into an argument about(!!), but I find more convenient for every day small volume shots.)
The reason I went for the Epson over the Leica? cost was one factor - you can get the Epson body for around a grand. The body takes Leica screw lenses (or M lenses with adapter) making it flexible, and I love the all analog controls for ISO, shutter speed, the cocking lever for the shutter - matched to the fact that the screen flips backwards it is exactly like using a film camera to all intents and purposes, along with the fact that it has a superb 1:1 viewfinder.
The whole cropped sensor thing I have never found a bother at all, especially when there are so many lenses to choose from. I simply put a 28mm f1.9 lens on my Epson making it a 42mm equivalent. Seems to be the perfect focal length for me, and I haven't even thought about the crop factor since. In fact, having just ordered a 50mm lens I can get an equivalent 75mm focal length from a very compact lens, so it can also be an advantage.
After all is said and done, I love its quirks, its build quality, the fact it was the first, and the fact that it is a little different. The Seiko analog watch hand dials are just awesome and it inspires me to take better photographs, because the 1:1 viewfinder means I can compose the shot with my eye, then bring up the camera to capture.
To look at the OP's question, I find rangefinders quite easy to use in low light, I find manual focusing much easier in this environment as I don't like having to wait for auto focus and dislike using a flash where possible. There are so many fast lenses in Leica mount available, you can get something very fast for quite a reasonable price. In fact, the low light ability is one of the main reasons I carry mine with me everywhere because I know it's ready for anything (forgetting mine is digital, of course, but the same is true of film)
The good thing about all this smoke, mirrors and bickering about Leicas (not referring to this thread especially) means resale is healthy should you decide it isn't for you in the end.
