| p.1 #1 · Nikon TC-20E III Question |
Forgive this silly newbie question, but this is the first teleconverter I've ever owned. I just received the Nikon TC-20E III today and when I was taking it out of the box I could hear/feel a piece moving inside the assembly. Upon closer inspection, once I remove the cap from the element, I can see a piece moving on an internal track.
First question...I'm assuming this is normal?
Second question...what is the part that i moving and why does it move freely?
