Nikon Nikkor Z Telekonverter 1.4x

Works excellent on the 400f4.5 Z S. Can’t see any quality differences or focusing issues.

Very easy to use and exceptional results! I do not see any degradation in my image results when using with either my 100-400 lens or my 600 PF. The results are amazing and the extra focal length a true benefit!

Z9+100~400mm/4.5~5.6 S lens with TC-1.4x. Great for taking fast-action sports pictures from any location around the field. Cropped images are included with this review; nice sharp images. I'll be using the same setup when sports resume in the Fall. P.S. - the 100~400mm lens is good; the TC-1.4x make it better.

Works well and gets great photos with the 180-600mm lens. I very impressed with the lens at 840mm f/9 even with high ISO. Photos in shade do have some problems and the heat rays. Love the lens!

Works well with minimal impact on image quality and enables me to keep a respectable distance from wildlife subjects.
