Related Questions and Answers

Q: 1. Can this teleconverter be used with the FTZ adapter?

A: Unfortunately, as of the date/time of this reply, Kenko has not listed any testing or information concerning the compatibility of the Kenko TELEPLUS HD pro 1.4x DGX Teleconverter for Nikon F being used with Nikon Z-mount cameras via the Nikon FTZ Lens Mount Adapter. As such, your results may vary.

Q: 2. Will this teleconverter increase f6.3 to f7.1 on a 100-400mm Sigma lense?

A: When you use the Kenko TELEPLUS HD pro 1.4x DGX Teleconverter for Nikon F you do lose one stop of light. So a lens with a max aperture of f/6.3 will let in the same amount of light as a lens with a f/7.1 max aperture when you use the TELEPLUS.

Q: 3. I have a D850,when using the 200-500 mm lens,will this teleconverter work?

A: Yes, it would be possible to connect the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F onto the Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR Lens. However, do note that this lens/teleconverter combination would become the equivalent of a 400-1000mm f/11 lens, and would not autofocus when connected to the teleconverter.

Q: 4. Is the 2x Teleplus HD Pro compatible with the Nikon Z 6 with the FTZ Adapter? I hope to use it with an Irix 150mm f/2.8 lens.

A: Unfortunately, this product is not compatible with the Nikon Z6 with the FTZ and the Irix 150mm f/2.8 attached.

Q: 5. Will this teleconverter work on a Micro Nikkor 200mm f4 D lens?

A: Yes, it will fit and you will lose about 1.5 stops of light.

Q: 6. Is this product compatible with a AF-S Nikkor 28-300mm f3.5-5.6 G zoom lens? If so, which of the lens/camera features will work and which will not?

A: It is compatible with electronic communication for exposure, etc.. but AF will not work given the slow aperture of the 28-300mm.

Q: 7. Will this work with a Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens and Nikon D700 camera? What are the shortcomings?

A: Yes, the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F would be compatible for use with the Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens on the Nikon D700 DSLR camera. Do note that as the Nikon D700 DSLR camera requires an equivalent maximum aperture of f/5.6 or brighter to maintain autofocus, and the Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens would be the equivalent of a 600mm f/8 lens when connected to the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F, you would not be able to autofocus with this setup. You would have to focus manually. That being said, automatic exposure, automatic metering, and Vibration Reduction capabilities should still be available.

Q: 8. Will this Teleconverter work with the Sigma 150-500 5.6-6.2 used on a D7200 body? Lens was purcahased in 2013

A: Yes, the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F would work with the Sigma 150-500 5.6-6.2 lens for Nikon F on a Nikon D7200 camera. However, it will not support autofocus or auto exposure functions or provide any communication between the lens and the camera.

Q: 9. Will this continue to keep autofocus using a Nikon D7200 with a 200-500 lens?

A: Yes. The Nikon D7200 DSLR camera has the ability to autofocus with lenses that have a maximum aperture of f/8 or brighter. When using a 1.4x teleconverter, while it increases the focal length by 1.4x, it also decreases the lens' maximum aperture by one f-stop. As such, using the Kenko TELEPLUS HD pro 1.4x DGX Teleconverter for Nikon F on the Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR Lens would make the lens the equivalent of a 280-700mm f/8 lens. As such, it will retain the ability to autofocus when using the teleconverter on the lens.

Q: 10. Is it compatible with the Nikon Z5 with Z to F adaptor and the Nikkor AF-S 70-300 mm F mount. Will AF still work?

A: Theoretically Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F will work in that combination and provide autofocus but only testing it out to really make sure you don't get any error messages. The good news is that you can return it within 30 days if it does not work. Just keep the box and all accessories and follow our return policy.
