I received my Canon FD mount "Lens Turbo" yesterday. So I took it for a walk this morning at a local park. Stacked a Nikon-to-CanonFD on top, and used two Nikon Series E lenses (economy line, single coated, and lightweight). All pictures lightly processed in LR, and not cropped at all. Nikon Series E 50mm f/1.8 Nikon Series E 100mm f/2.8 Some more Yellow Flags Irises If you want to see big size, you can open the image in a new tab or window, change /s960/ to /s2048/. Overall I'm quite happy with it. Bottom line, it is one more tool/toy in the bag. You gain about half stop more light, and it gives you shallower DoF. Don't expect it to automagically give you 3D FF look - that depends more on the lens, light and how you compose. You're all welcome to post shots taken with "Lens Turbo" in this thread. Please write down the main lens when you post. I think I'm going to try some 35mm and 28mm when I get a chance.
