Are TLR's rangefinders?

[Doug]

...I now know the TLR is not a rangefinder (I thought it might be when I first posted) ...
I know that a TLR is right up on my list now after the Rollei 35RF. They both share the same traits and strengths, but one with a 6x6 negative!

Hi Daniel -- You can have 6x6 negatives with an RF camera too! See the Mamiya 6 or Super Ikonta B, and others. And also other roll-film frame sizes like 6x4.5, 6x7, and 6x9 just for some of the more popular formats.

TLRs are mostly 6x6cm, though there have been 4x4cm and 4x5 inches too. But in general, there are more variations in film format for RF cameras than TLRs.
