Tamron vs Canon SP Autofocus 2x Pro, November 6, 2008 By This review is from: Tamron SP AF 2x Pro Teleconverter for Canon Mount Lenses (Electronics) I am a professional that uses Canon L lens only and was using Canon Teleconverters both 14x and 2x that I use extensively without a Problem. But, I have decided to go with the Tamron SP Autofocus 2x & 14x Pros.
Why? I have done extensive testing on the four teleconverters and have found that there is no noticeable difference beween like teleconverter. The only exception is the Canon's are heavier and longer and protrude into the lens but are not any better than Tamrons. Another professional friend of mine also looked at the results and was equally surpised.
Tamron's will work on more lens as they do not protrude into the lens like the Canon's do. Remember that lens will only auto focus if you are f8 or less (bigger)lens f-stop. If you add a 2x to an f4 lens it will not autofocus. I manually focus when I have a long telephoto lens on to get out to 800mm but this means with my f4 lens it is really now f8 so requires manual focus. Tamron has a very good little... Read more

Double your focal length, August 10, 2006 This review is from: Tamron SP AF 2x Pro Teleconverter for Canon Mount Lenses (Electronics) I realize now that I probably would have been fine with the non-PRO version of the teleconverter -- I'm not certain whether the differences between the PRO and standard actually justify the extra cost (unless you use Canon L lenses perhaps). But that is neither here nor there.
The Tamron SP Autofocus 2x Pro Teleconverter doubles your lens' focal length and adds two f-stops (meaning you'll be getting 1/4 the light with the teleconverter). This is the same for all 2X teleconverters. The addition 2 f-stops will make it difficult to use autofocus unless you have a fast lens and lots of light to work with. You'll also want to use the teleconverter with a long telephoto lens.
The Tamron SP Autofocus 2x Pro Teleconverter works as advertised with 35mm and digital cameras. I've had no problems using a Tamron 70-300mm lens with this teleconverter on a Rebel XT aside from the expected auto-focus issues. There are a few issues I noticed though beyond the typical problems... Read more

poor performance on full frame, June 3, 2009 Amazon Verified Purchase This review is from: Tamron SP AF 2x Pro Teleconverter for Canon Mount Lenses (Electronics) I put this on a 135 f/2L lens on a full-frame Canon, and the result is pretty mediocre. There is a huge amount of vignetting, even stopped down to f/8. Looks like the vignetting might not show up much at f/8 if cropped to match a smaller sensor. Exposure is off by 1.5ev or so, and images have a soft look with a fair amount of chromic aberration.
In the box was a little warning from Tamron that says "This teleconverter is not designed for digital use."
