Used Tamron 1.4x AF Teleconverter for Canon EOS.

Talked to a person on live chat. They said this is absolutely the one I had to have for my setup. Did not read on my lens at all. Had too send back and only got refunded when I paid. I am supposed to have the pro 1.4 they say now.

I AM USING THIS TELECONVERTER WITH A TAMRON 150-600 G2 LENS - IT WORKS AT ALL FOCAL LENGTHS MAINTAINING AUTO FOCUS - PICTURES ARE SHARP

Perfect addition to my Canon 100-400mm lens. Gets me up to a whopping 570mm equivalent. And it's small size fits easily into my otherwise "busy" camera case/backpack.

After reading many reviews about the 2x and the 1.4x Tamaron Teleconverter, I tried both. As the review comments stated, the auto focusing on the 2x was quite slow and not acceptable for me. The auto focusing for the 1.4x was much faster and acceptable for me. I will only use the 1.4x Teleconverter for very specific long range photos, so the slower auto focusing will not be a problem.

I used this Tamron 1.4 X extender with my Tamron 18 - 270 zoom on a Canon 60D, and the results were just what I would have expected - moderate but acceptable effect on sharpness. A good addition for occasional "long shots.." Yes an excellent 120 - 400 zoom would yield superior results at a cost of $1,000, but for less than $150, a great alternative for that once in a while need. Also, light and easy to carry. If you must have auto focus and image stabilization then go for the big bucks option - I come from the time when neither was available, but photos were still sharp.

Easily attaches to my Canon 400 mm lens but cannot autofocus with my 50D. Still, provides clear pictures and is a great value compared to purchasing a 500 mm lens.

I heard about this little gem from a photographer on Pbase.Considering the cost it performs admirably better than I had expected.I use this with my Canon 400 5.6 L lens for bird photography.It still maintains autofocus reasonably well,although it tends to hunt a little.Flight shots are more challenging but possible especially if the bird is large.Photos come out nice and sharp but you must use good technique,a tripod is recommended.This has become an invaluable tool for me and gives me the kind of reach I need for a very low cost.I shoot even small birds like sparrows and warblers.Highly recommended! Bird photography within the reach of us mere mortals.

A good buy. I do reccomend this but if you are planning to use it for very high quality professional use, or your lively hood depends on it, I might go with the major brand. I understand it is a little sharper. And more expensive.
