Q & A

Does this teleconverter support autofocus?

• This teleconverter only supports autofocus if the effective maximum aperture of the lens and teleconverter combo does not exceed the limits of your chosen Nikon camera. This teleconverter adds one stop, so f/2.8 becomes f/4, f/4 becomes f/5.6, f/5.6 becomes f/8, etc. Check your manual or feel free to contact us to verify if autofocus will work.

Can I use this teleconverter with D-series lenses?

• No, this teleconverter isn’t compatible with D-series lenses.

Can I use this teleconverter with a lens that isn’t listed above?

• If the lens you want to use this with isn’t listed above, rent at your own risk. Older legacy lenses may mount but not provide autofocus support. As always, please contact us first if you’re unsure.
