Have Nikon D70 and need a teleconverter for my Nikon 300mm f4 AF ED (not S model) prime lens. Searched Nikon web site and other sources without luck, so tried Kenko Pro 300 x1.4 at local Toronto store and it worked for metering and AF. A Sigma converter provided metering, but not AF. Will purchase Kenko if no member can direct me to a compatible Nikon converter
Thanks,
