Megan --NEX-5 & Kern-Bolex 50mm f1.3 Projection Lens. Click to enlarge.
I have grown quite fond of this little lens. Ultra fast and yet very sharp, all wide open. In fact, I am not able to make it stop down, yet. There is too much purple fringing against strong lights for this lens wide open, but I found it to be superb for indoor shots, especially of people. I have another similar projection lens, the Astro kino Color 50mm f1.5 , but can't seem to locate it. Would be interesting to compare the two. On the other end, there is a B&L 120mm f1.9 projection lens I am also trying to make into a lens. So many toys, so little time :)
