The Mamiya C330 Professional F kind of looks like a Rollei or Yashica TLR, but it's bigger by a couple of centimetres in every dimension, and it's definitely heavier. But what you get in return is interchangeable lenses and better close focusing ability, which may be worth the trouble. This C330 Professional F is in excellent condition, except for an ID engraving on one side of the front lensboard WHO THOUGHT THIS WAS A GOOD IDEA? Argh. Anyway, only minor wear otherwise, and the light seals are new. The included Mamiya-Sekor 80mm f2.8 lens is in very good condition, with minor internal dust, very light coating marks on taking lens.
