This lens showed up yesterday, a little Christmas present to myself. I have been watching the used market for quite some time now, but Amazon offered an awfully good deal here recently. I think this is only the third brand new lens I have bought in K mount. I had a Tokina/Vivitar 17mm lens back in the film days that I loved because of the FOV and the incredible hyper focal range. I had hoped that the DA15 would fill that niche, but it is a different lens (don't get me wrong, I do love the DA15). My initial impression is favorable so far. The other option is the Venus Laowa 12mm, but the $950 price tag is a deal killer for me. Anyway I will post photos in the coming days...
