Review on Pentax K-Mount HD DA 15mm f/4 ED AL Fixed Lens for Pentax KAF Cameras (Limited Silver) - Top-Notch Image Quality and Distinctive Design by Andrea Smith

Good compact size. The review is based on using K3ii. So far it hasn't met my expectations. Overall the lens is a bit softer than I expected, I've looked at other samples online and I don't think it was just mine. I have some good photos of this, but it takes some learning compared to some of the other primes I've used. I plan to use it extensively on a hike this summer and will update my review when I'm done if necessary.
