MTF are making my lens adapter.

MTF - Alister C' B4 to F3/FS100/Canon lens adapter

So here it is. The first one off the CNC machine with many more to follow in the next few days. There will be an additional lens support bracket on it by the time they ship and of course they will be completely anodised. It requires the use of a 2/3″ lens with a 2x extender. Optical performance depends on that of the lens, so an HD lens is highly recommended, however if you have an old SD lens kicking around it may be useable. When using the adapter you use the 2x extender. The total magnification is 2.5x so a 7.6mm to 152mm 20x ENG lens becomes a 19mm to 380mm lens. There is also a 2.5 stop light loss so a f1.8 lens becomes a f6 lens. The adapter will come as a kit for the PMW-F3 or FS100 for £1150. If you wish to use it on a Canon DSLR with an APS-C sized sensor (7D, 550d, T2i etc) the price is £950.
