Editorial Reviews:

Product Description
The 1.4X teleconverter will increase the focal length of the master lens by 1.4X and make the lens one f-stop slower. In addition to increasing focal length, this teleconverter allows greater magnification in macro since the Minimum Object Distance (MOD) of the master lens does not change when used with the teleconverters. The 1.4X teleconverter can be used with both AF and MF lenses. AF will be retained if the master lens is F/4.5 or faster.

Tamron Teleconvertor for Canon October 7, 2008
F. Taylor (Virginia, USA)
I've had this product for only 3 weeks. It has been used on two occasions to test its viability with my system, a Canon EOS 40D. I've used the teleconvertor with a 70-200 L Series Canon lens. Results have been very satisfactory with a total of approximately 50 photos that have been reviewed carefully with Photoshop Elements 6.0. The af feature works flawlessly with my lens, and my very sharp lens still produces excellent results, only with a longer focal distance. I'm very pleased at this point. I wanted a neutral extender with no coloration and got it - at a much better price than one from other sources.

i mainly ordered this for my canon 70-200L lens but noticed a loss of sharpness and not enough zoom for my needs.it did seem to work ok on the 28-105 with no auto focus problems, on both lenses.maybe the canon version is sharper but its a bit over priced.i may sell the 70-200 and get the 100-400L with image stabilize, when i can afford it.

Auto-Focus Still Works!!!!! February 28, 2008

I'm using this teleconverter on a Canon 100-400L lens with my Canon 20D and 5D. The autofocus still functions just as the manufacturer claimed it should, and it even seems to focus just as fast as before. There is a detectable drop in sharpness however, which is to be expected with any teleconverter, especially when you're using a zoom lens. This TC would be an ideal choice for people with prime lenses who need autofocus intact (i.e. for birds in flight) and maybe for zoom lens owners who don't intend to make big enlargements or crop their prints heavily.

I was able to compare it with the more expensive Tamron 1.4x Pro and found absolutely no difference between the two in image quality. Autofocus doesn't even work with the Pro version when you've got a slower lens like mine (f/4.5-5.6) and Tamron even says there's no real advantage to the Pro TC unless you've got a fast 2.8 lens.

I only wish I owned a prime telephoto lens to check if it's worthy of a five star rating.
