.1 Autofocus cannot be used.2 Autofocus can be used when attached to an f/8-compatible autofocus camera with the AF mode set to AF-S.3 Autofocus can be used when attached to an f/8-compatible autofocus camera. Other lenses cannot be used. Do not attach other lenses, as the rear lens elements will touch and could damage the teleconverter elements. The Vibration Reduction (VR) function operates with VR lenses when used with the following Nikon SLR cameras: FX/DX-format digital SLR cameras, F6, F5, F100, F80 series, F75 series and F65 series. Depending on the combination with digital/film SLR camera, the teleconverter's focal length information may not display correctly in Exif data. Please refer to the teleconverter manual for further information. AF-S TELECONVERTER TC800-1.25E ED is a supplied accessory of the AF-S NIKKOR 800mm f/5.6E FL ED VR and not sold separately.
For details, refer to the product's web page. When effective aperture is f/5.6 to f/8, autofocus is possible when attached to an f/8-compatible autofocus camera.
But the focus point that is used for autofocus or manual focus with electronic rangefinder is limited to that located at the center. Also, focus may not be achieved when shooting low-contrast or dark subjects.
I have a Nikon D3s, and an older Tamron SP AF 300mm 2.8 lens (Nikon F-mount), to which I would like to add a teleconverter for long-distance birding shots. Everyone says that the Nikon TC-20e III is the best, but I can find no way to make it work with a Tamron lens. My research indicates that it is only compatible with a small list of Nikkor AF-S and AF-I lenses. Is there any way to use this setup? Any type of adapter or converter that makes this possible, or do I need to go with the lower quality Tamron SP 2x? Also, if I definitely cannot use the newer Nikon teleconverters, how would the older Nikon TC-201 compare to the Tamron teleconverter? I know I would have to go with manual focus, but I often do so anyway.
I am most concerned with sharpness and image quality. Any information would be great appreciated, and do have a lovely weekend!A. DeLeeuw5th Day Photography.
I definitely did NOT want to file down the tab on the teleconverter, but was hoping there might be some sort of adapter. Oh well.In terms of preferring the Kenko, is that based on sharpness/image quality, or some other qualities.
I will check out the reviews.thanks!As to the older Nikon TC-201, any reviews from anybody regarding the image quality comparison? I can find reviews from the time it was released, but nothing that compares the glass quality to the newer Tamron or Kenko teleconverters.
