Gino's Pizza (2009) -- G1 & Kodak 25mm f1.9. Click to see larger.
I feel like a little kid in a candy store lately with the Kodak cine lenses. I tried them with the NEX-5, but the vignetting is too severe. They are near perfect on the Panny G1. Like them all, but the 63mm f2 and the 25mm f1.9 are two of my favourites.
The Cine Ektar II 25mm f1.9 is one of the few 25mm c-mount lenses I have tried on the G1 that does not vignette wide open. Even stopped down a bit, it's still quite acceptable. I would rank this lens up there with the Kern-Paillard 25mm f1.4, but the Kodak is sharper, vignettes less, and has much better corners. Of course both lenses render picture slightly differently, but in terms of value for the money, the Kodak is way up the scale.

Like most of the Kodak cine lenses I have, this one has very stiff focusing due to dried up grease. It will need to be cleaned, lubed and adjusted.
