Irix 15mm f/2.4 Blackstone.  The Irix 15mm Blackstone is a manual focus, super-wide-angle lens.  Less boring images coming soon (hopefully).  I need more time to actually get out and shoot somewhere, but it's winter now and my options are more limited.  I posted an unboxing video on YouTube.  UPDATE:  I decided not to keep this lens (returned for refund), but it was NOT due to the quality or any problems.  I simply found the 15mm focal length was too wide for most of my shooting and it would have been a bad idea to keep it and not use it very often.  I was very happy with the build quality and images made by this lens.
