My first TLR was a Lubitel in 1967. Then it was all 35mm till 1991. Then I bought a Yashica Mat 124-G. Sold it in 1994 for some extra to buy a Mamiya 645 Pro.
However in 2007 I bought a Yashica Mat 124-G again, in very good condition and made a CLA. It's working perfect and I like the camera very much for IR-photography.
