Fun accessory
By C. Piekarz
I purchased this for astrophotography purposes, I'm using it with a Canon Rebel XSi (EOS 450D).As the description says, using this costs you 2 stops. Autofocus has been hit and miss for me; my 50mm prime searches a bit, but usually focuses fine. My Tamron 70-300mm Di LD lens won't autofocus at all.Quality-wise, I get noticable purple fringing in some images, but nothing that's uncorrectable.I'm definitely recommend this to anybody searching for a cheap teleconverter - If you want quality though, get the Canon version.

Works great
By B. Kocen
I wanted a larger lens and not the price.On my 70 to 300mm cannon lens it works ok.At higher lens values it has a hard time auto focusing but just switching to manual solved that. I shot mostly race cars, durning the day so the loss of 2 f-stops is not a problem. Have not tried it inn teh early or late hours with lower light. Pictures are sharp and clear.

Tamron 2x teleconverter
By N. Cornell
Works great. The only problem is the f-stop is a little off, but with a little practice you'll have it working perfect in no time.
