Question: Has anyone used this with the Tamron 150-600?
Document: Perhaps I got a bad one but I found this teleconverter completely useless. My equipment consisted of a Canon 60D and the latest Tamron 70-300mm telephoto lens with VC. I'm aware of the limitations as well as the probable need for manual focus. Unfortunately, no matter what settings I used, tripod or handheld with image stablization, or how well I focused the lens, this teleconverter could not produce a sharp picture.
My husband drives a truck for a living and now can photograph all of the wonderful sites. A must have for anyone who wants to take clear photographs.
nowhere in the item description did it state " this teleconverter is not designed for digital use"  It does work with my XTi/ tamron lens
Was looking for a inexpensive way to get 600mm telephoto for my Canon 20D. Decided to try Tamron 2x teleconverty.... here are my initial assesments:Pro's1) Quality/construction is good....
Great product. I read other peoples reviews and opinions before I made up my mind and while they were mixed I thought I would try it. It has turned out to be one of the best photo equipment purchases I have made. Tamron has yet to let me down.
Even though it is advertised to work on a DSLR it will not fit the Canon lens. I called the Tamron tech support and they affirmed it will not work on digital cameras. It resides in the useless junk pile along with other stuff I bought on Amazon that did not perform. The resellers advertise stuff that does not fit the manufactures description. Too bad as the price is so low it does not warrant returns.
I was a bit concerned about other reviews stating that the Tamron 2x Teleconverter didn't work with any but Tamron Lenses. I found that to be false. I can mount my Tamron 18-270, Sigma 200-500 and my Kenko 1.4x extender to this extender.The 2x Teleconverter mounts without issue to my Canon EOS 60D.I did find that I could not mount this Tamron 2x to the Kenko 1.4x.
Description of this product is incorrect. This teleconverter will ONLY MOUNT TAMRON LENSES ON A CANON CAMERA BODY!!! !The instructions included with the teleconverter specification notes state "This device is designed specifically for use with Tamron lenses. It is not compatible with other lenses. "This is in direct conflict with the Amazon description "Tamron  AF 2X Teleconverter for Canon mount lenses"I am in the process of returning the teleconverter. It was very disappointing Xmass present.
Tamron AF 2x teleconconverter for Canon Mount LensesWhen I first tried to use this, it would not attach to my EF lenses (18-55mm zoom, 75-300mm zoom). I am using a Canon EOS T1i.The teleconverter would fit very snugly on the camera but I could not get either of my lenses onto it.So I was quite upset. I am stationed out of the country and had purchased it through Amazon while on a visit.
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.
Answer: I have not.  But I have used it with the Canon 100-400mm zoom, and even in combination with a Canon 1.4x extender.  It works fine, with (at most) only slight loss of image quality.
