Kiron MC 24mm F2 and Sigma XQ MC 18mm F3.2. Both in Konica AR mounts and in mint condition. Was an impulse buy and got both for 50$. Thought the Sigma was a fisheye but it is not. I have read a little bit about the Kiron and it seems like a really good lens, but there is not much out there about the Sigma. Both seem pretty sharp just from playing around with them on my PL5.
