In Full Blossom -- NEX-5 & Astro-Kino 65mm f1.5 Projection Lens
The Astro-Kino 65mm f1.5 projection lens has many qualities of an old cine lens, especially the swirling backgrounds. I didn't expect a projection lens would behave this way, but this particular lens was designed for 16mm projectors so the imaging circle probably did not need to be very large. Another interesting thing I found out is that most projection lenses is sharper at infinity than close up, which makes sense when you think about it.
A lot of people pay a lot of money for lenses like the Dallmeyer Speed 1 inch f1.5, which share similar swirling backgrounds as this lens. If this is what pleases you, you should keep an eye on one of these lenses, which turns up on eBay once in a while for $30 to $50.
