Hi
I,ve just joined the Bird Forum I found it while I was looking for a review on the Sigma 2 x Teleconverter has any one used one of these?
Hi MartArt,
I haven't used one, but on behalf of Admin and the Moderators, welcome aboard ![]()
Hopefully someone will be along soon who can assist.
Hi MartArt,
I previously used one when I had a Nikon film camera- both with Nikon & Sigma lenses. Make sure you get the Ex series convertor which is of robust build & uses apochromatic glass. There is little chromatic aberrance or distortion with it & I found it to be a good robust quality piece of kit when used with decent lenses.
