Nothing to complicated with the old rangefinder cameras, they are a little slower to operate and take some time to focus etc. especially if one is used to do everything cameras etc. If you have shot analogue cameras in the past not much to overcome.

Many camera manufactures have made them, I would categorize them into a few different camps.....the really old school one that had interchangeable lenses and those that hade fixed lenses on them.....the former IMO are the most like the "classic" Leicas that many think of when thinking "rangefinder" camera.

A lot of folks call the older Canon Rangefinder cameras the "poor" mans Leica (their words not mine).....folks seem to prefer the Canon model "P" over any of it predecessors/successors due to it's simplicity and lack of an exposure meter etc. Canon 'P"'s can be found on any number of sites selling used camera gear, they range from 175.00 to 300 sometimes with a lens. Personally, I shoot with the Canon 7, dead meter and all and find it quite capable of making nice images.

If one wants a meter the Canon 7 series is the way to go. The 7 to some appears cluttered (I shoot with it and it's not an issue for me) and opt for the 7s or 7z. Canon 7's can be found at very reasonable prices 75 to 180 higer end with lens, while the 7z's can go for well over 300.

The nice thing about Canon is that they also share the same lens mount as the Leica (M39) and the lens range is quite extensive.

Here are a few pics from the net.....

Canon P in black....lots of money for this one!

Canon 7....not as much as the P but still over a "grand".....that's why mines "chrome"

Anyway I hope this helps.

Best, Ben

Yes, I like Canon and have owned and shot other manufactures as well.
