I am a Medium Format guy who can’t afford a Hasselblad or a Rolleiflex, so I have several working TLRs which I use regularly. My favorites are a Yashica LM, similar to the Mat124, and a Ricoh Diacord. I also have two Argus TLRs and a Ciro-Flex F. The Argus cameras and Ciroflex are American made and considered second rate. So how bad, or good are they, really? None have light meters or double exposure prevention and all use the “ruby window” for frame counting.
