One Step Beyond
Crutchfield Customer Review (What's this?)
This Teleconverter marries perfectly with my G Master 100-400mm lens, without any change in auto focus speed, and virtually no degrading of image. Just what the doctor ordered for reaching out to capture far away subjects, or getting that close up head shot. Great price and great service from Nate and the crew at Crutchfields (as always).
Pros: Image quality, auto focus speed, and convenience.
