Review on 📷 Nikon TC-20E II (2.0x) Teleconverter AF-S: Optimize Zoom Capability for Nikon Digital SLR Cameras by Sean Flint

Received this converter today. Tested on D4s with AF-S Nikkor 600mm f/4D IF-ED II lens. It works, which is good for me as my TC-14E III does not fit this lens. Auto focus works well. The maximum F is F8. Several shots posted here. All full screen, no cropping. The item is soft. I will update this review later when I take more photos.
