[QUOTE="WayneF, post: 512041, member: 12496"] You never said what your problem was, so I doubt we can suggest any help. My stab at it however, would be to abandon the lens converter and use the regular Nikon lens, and higher ISO if you need it. I suspect the gadget is the problem. The converter, as well as for converting lens mounts, appears to be a wide angle adapter, like is sometimes used on astronomical telescopes, to provide a wider field of view. The opposite of a teleconverter, and the shorter focal length makes the aperture seem wider too. Telescopes are fixed, but on a camera, we can instead simply use a wider lens, and eliminate all that extra distortion causing glass. And today, high ISO works really well, esp for movies. The movie mode will be auto ISO except in camera Manual mode. And it works. Try it. I don't understand their G and F distinctions, they seem to have it wrong. All Nikon DSLR is F mounts. The G adapter says the manual aperture is required, no electrical connection. However a Nikon G lens means there is no manual aperture, and electrical connection is required (and most are G lenses today). Sorry, but if I had a Nikon camera and a Nikon lens, I think this contraption is the last thing I'd want. [/QUOTE]
