leicaflex lenses vary widely -- to get a more sane idea, look up KEH camera brokers and see what the lenses sell for there.

Leicaflex bodies are priced somewhat less-- I bought a EXC-plus Leicaflex SL2, 50-anniversary edition, for under $700. Users are less than $400 for the SL and SL2, with the SL2 more desirable.

Lenses for leicaflex SL and SL2, if purchased new when the camera was new, would likely be 2-cam, but it is easy to check.
