The FT1 adaptor is an amazing item. It converts my Nikon VR 70-300mm lens into a 189-810mm VR lens when used on my V1. The lens still has the vibration reduction and it's auto focus abilities with no loss of image quality. I get excellent results hand held with this combination. For the price it is a real bargain. Have you priced what a DSLR lens with a reach to 800mm would cost? I have and it is not pretty. Then there is the weight to consider. For airshows or birding the Nikon 1 series with the FT1 and various full size Nikon lenses is an excellent alternative. The FT1 has no glass so does not degrade images and the clever electronic contacts transmit all the necessary information so that the lens works properly with the camera body. The adapter supports AF-I and AF-S lenses, and it supports VR on those lenses where the lens has that feature. The Nikon websites have lens compatibility guides. Search for 'Mount Adaptor FT1'. Due to weight considerations, with a lens like the 70-300mm fitted it is recommended to use the tripod adaptor on the FT1 for mounting on a tripod or camera strap, rather than the tripod mount on the camera body. You may need to have a firmware update on the V1 to use the FT1. This is a free update from Nikon. The Nikon 1 V1 is supported from firmware version A 1.10/B 1.10, Nikon 1 J1 from firmware version A 1.10/B 1.10 according to Nikon. They also say Auto focus may be less precise S: Shutter-priority auto, A: Aperture-priority auto, or M: Manual is selected for Exposure mode. I use P: Program mode with excellent results. BTW, 'FT1' stands for 'F to 1'. That is, Nikon F mount to Nikon 1 adaptor.
