I had a Yashica T4 Super and recently sold it. The prices these cameras sell for are, IMHO, completely out of whack with their actual value as photographic instruments. The lens is nice and sharp in the centre, but my copy was noticeably soft and darker in the corners. I found the camera pretty unremarkable overall. I acquired my Leica Minilux for little more than what a mint condition T4 Super typically goes for, and my Contax TVS cost half the typical price of a Yashica. The T4 was a great solution when it cost a third or a quarter of a Leica/Contax compact, but with current prices I think it's difficult to justify the attention the Yashica garners.
