>>3284631If you get the mamiya, you will actually use it a lot and it will probably become your primary camera. Big and heavy, but the results will be amazing. Ignore cucks who say it's too similar to 35mm, it's just not. 3:4 ratio is patrician, and even on 400 film the grain disappears.
If you get the yashica, you will go "ooh, big squares" for a couple of rolls and then leave it on a shelf, because TLR's are awkward as fuck to use, weigh a tonne, are impossible to frame with, and Yashica lenses are trash.
