The only "keeper" I got from a short jaunt out with my new-to-me 15mm Limited. I've been wanting that lens for a while now and one came up on MPB for a great price. It was a bit beat up but the optics were perfect, said the listing. I received it Sunday and the optics are indeed fine, but the focusing ring had excess movement and soon the focusing stopped working altogether, both manually or AF - the ring just won't move.
But I had a blast with it for the brief moment I had it and it was operational.
