I have a FM3, and I need a teleconverter.
Nikon have a lot of different converter.
Wich one can be used on the FM3.?
Wich one have the best optical quality.? best contrast.?
Could you please confirm that the Kenko Pro TC 2X and 3X works well on the Auto-focus of the 80-400 VR lens. I was told that the auto-focus will not work for my Nikon 80-400 VR lens at that time when I wanted to puchase it.
For what it's worth, I have also successfully used the Kenko 1.4x TC with the 80-400 VR on an F100 (see cropped scan of slide below) - both AF and VR functions were preserved. In theory, the 2x and 3x should work, as I believe they have similar connections to the 1.4x TC, but the caveat is that the light available when using these on an f5.6 lens may be insufficient for the autofocus system - especially for the 3x TC. Perhaps you could try them out in local camera shop, if noone else has had experience of this combination.
By the way, the quality of the images using the 1.4x TC has been well above my expectations - the scan hasn't done justice to the original image, but at least you get some idea of the results from this combination.
