This lens is much better than I had anticipated or imagined. I really didn't know how much I would like it until I made a few shots that weren't normal for the situation or composition, but it rendered the images far greater than thought possible. The resolution is fantastic.

Great fish eye lens. Very sturdy and quality of pictures is on par with Tamaron, Canon ect. This is a manual focus and if you are not used to manually focussing on object this can be very difficult and the results are not great.

Great build, very sharp, low distortion for 11mm. Cap needs to be carefully placed on and removed. Don't stay very well put. This is an only minor thing. Overal great buy.

Well, it's 11mm! That pretty much sums it up. But here's the rest... I'm reviewing the Firefly version, which is the plastic version. The Blackstone version is the metal version, and I assume it's built better, though with identical optics. It's pretty easy to sum this lens up.
