I am new to this forum. I shoot both film and digital. In film I shoot 35mm and 120mm. A Canon A-1 and Olympus OM-2n are the go to 35mm, while a Pentax 645 is used for 120mm. Digital bodies are Canon 5Dii (for landscapes and artistic work) and 7Dii for birding and other wildlife.
Do you mean 120 Format film? That shoots a 6x6cm, 6x7cm, or 6x4.5cm negative.
I used to have an Asahi Pentax 6x7 (mirror LU) camera. Only had two lenses, though, a 45mm and a 135mm.
