Tamron SP AF 1.4x Pro Teleconverter User Reviews
works well for what it does | Rating:
“..it works OK — Using a D-300, I’ve tried it with the 80-200mm f/2.8 (which turns it into roughly a 112-300mm f/4 lens) and the autofocus is still very quick. The quality of hte photo appears about normal (a steady tripod would probably be very helpful; i was using a monopod).” – by P. Shepard
Not too bad | Rating:
“The auto-focus works ok in bright light, the VR works too, to my surprise, unfortunately image quality is not top notch but well enough that most photos come out pretty good. Exif data does not show the extra length of the lens, 300mm to 620mm.” – by J-Mon
