The Yashica 124 series seems to have cult status while the earlier D, 635, Yashicamat, and several other models are often overlooked. Their optical performance should equal the 124 series, but they lack some operating conveniences. The Yashinon, not the three element Yashikor, lenses I've used have been good. Yashica reliability isn't as good as I'd expect from a Rollie or perhaps Mamiya.
