Title: Tamron 2x Pro Teleconverter
Review: I am very pleased with the teleconverter. I believe the ad was a bit mis-leading in that it called out a 700 item number and a 300F arrived, twice actually. After looking on the web I do not believe there is a difference in the two lens. Yes it does not have the clarity that one would hope for, it is much better then I thought it would be. I can use it on my 70 to 300mm Tamron lens and hand hold the camera and the pictures turn out great. Not as good as the 300 mm lens itself, but really not bad at all. Much less expensive then going with a 300 to 500mm lens. Since it will never be the primary way I shot pictures it is a great tool for the occasional time I will use it. The autofocus does work but not all the time, but expected that. I would recommend this lens to anyone...
