The video above shows off a brief overview of LensBaby's interchangeable optics system such as their 'Composer' and 'Tilt Transformer'. The LensBaby optic swap system allows you to switch to different lenses with slightly different tilt-shift like effects from pinhole, zoneplate, dreamy, soft focus, vintage, fisheye, and more. Although it produced fun and creativity, I personally was not a fan of having to swap out Aperture discs. They do offer adapters that will allow you to mount manual Nikon lenses but only for MFT (Micro Four Thirds) systems and Sony NEX cameras. Well, I have to admit they've come a long way from where they originally started years ago and have just recently introduced a new 35mm Optic Lens with 12 blade adjustable Aperture and will work with Canon EF mounts. Now we're talking!
The new 'Sweet 35' optic is definitely something i'd rock just to get out and get creative. Besides the smooth bokeh you'll get from a 12 blade aperture, it has a minimum focusing distance of just over 3" inches. From F/2.5 - F/22 dialed in on the optic you can get select focus or most in focus, along with that trademark Lensbaby blur. On Full Frame Cameras, there could be a slight vignetting, but that just adds more to the popular artistic throw back look people are going for.
