[QUOTE="Sarum Stroller, post: 614422, member: 43522"] To my surprise, my SP 'Superior Quality' Tamron 70-300mm f4-5.6 VC works surprisingly well with my Sigma Apo 1.4 converter! This gave me an equivalent of 560mm on DX D7000 and the Tamron's renowned and excellent VC really reigned in camera shake. BUT, I still wouldn't use AF, would stop down to f11 and only use in bright conditions with high contrast situations. I cannot answer regarding a 2 times converter (even more doubtful quality, slower too and the Sigma Apo 1.4 is a known quality item) and I think that you probably have the much cheaper Tamron 70-300mm too, with which it's difficult to get really sharp shots on its own above 200mm (I used to own one). So, as others have said, quality and compatibility doubtful - now, with my D7100, I prefer to use the 1.3x crop function on the camera in such conditions as it's always available. [/QUOTE]
