Got my baby today; I'm hooked! here are the first shots with the f5.6 aperture ring. 1. 2. 3. Tech details: 10D, Lensbaby 5.6 aperture ring, RAW, vignetted the first image, usual Curves. Side note - Matt (MD), the lens is not plasticky as I thoughtitwould be. Not saying it is built like a tank either. I love it. Havetotry out the f4 and f2.8. Not a big difference, but if you are a member of DWF, the price is US$89.99.
