Tamron 1.4x Teleconverter for Tamron Lens on Canon AF Camera
The 1.4x teleconverter (also known as a tele-extender) will multiply the focal length of the existing Tamron lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300mm lens will effectively increase the focal length to 420mm. A lens set to f/2.8 will now be f/4.
Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm. However, full AF operation is only possible with lenses with open aperture of f/2.8 or brighter. Please be aware that AF will work properly only if there is enough light and contrast on the subject to activate the camera's AF sensors. Manual focusing is recommended when using lenses with smaller open f-stop value than those given above. Not recommended for use with digital cameras.

I used this with a Canon EF 70-300mm f/4.5-5.6 DO IS USM lens on a Canon Digital Rebel XTi. I was able to get some very good shots with this combination in good sunlight, (on flickr tagged with the lens and extender). Obviously I am not expecting as good of results in poorer conditions. I am curious to see how the 2X performs. Autofocus operated well even at 300mm.

It is small and easy to use, but be careful with it. It can be really soft, especially with sports I have found. I don't have the money to afford the Canon by a long shot, so I figured this was the next best thing with all the reviews it had that made it sound fantastic. Don't get me wrong, it works well, but save your money. For a photojournalist that needs extra focal length quick and at a decent price, this works, but for sports I've had mixed results. Go with a bit of caution, but I'm not giving up on it yet. IS and non IS seems to have a noticeable difference so try them both out and see what you think. Fun to put my 50mm 1.8 on it for macro shots though, talk about saving some serious cash! One of the better highlights. Over all does the job, so if you need something practical for your wallet and your job, this is a decent choice.

Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
Tried with Canon 50/f1.4, Canon 85/f1.8, Tamron 18-270. Zoom had trouble with the AF in normal light, all lenses had trouble in low light. Would rather have a 2X especially since the aperture decreased by 2 stops, not 1 as expected. Probably keep it for the occasional macro use.

The Tamron 1.4 Teleconverter is a great addition to my camera accessories. The extender delivers crisp and clear photographs and functions perfectly with the cameras auto-focus feature. I found it to be of good quality and fairly priced. I'm very happy with this product.

Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
I love photographing wildlife, especially birds. The 1.4x added to my 75-300mm zoom, lets me get in that much closer, but adds almost no extra weight. When out in the field I am usually hand-holding my camera rather than using a tripod. When shooting really close up, the extender does show more softness and shake, so I have to take extra care to hold steady or brace myself. Still, a small price to pay to get the extra close-up shots.

Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
I am using the Tamron 1.4x teleconverter with a Tamron 28-300mm VC lens on a Canon 20D camera. I have found it to be a good investment in giving me a little extra focal length at the 300mm end. As stated in the instruction, I would not recommend using it below 50mm. It causes a increase in chromatic aberration.
Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
Just got my converter in the mail. I own the standard 18-55 USM IS and the 55-250 Canon USM IS lenses to go with my Canon Rebel XSi. The lenses will not fit the converter. I'm gussing I need an extention tube to make it work.

Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
I have been using this product on a Sigma 50-500mm lens as well as a Canon 24-105 is L lens with good results on both!
It is sturdy and compact and easy to connect to both lens and camera, consequently I have it with me at all times.
I wish that it would connect to smaller some of the lenses that I use for Macro like a 65 mm

Comments about 1.4x Teleconverter for Tamron Lens on Canon AF Camera:
Used with an EF 70-200mm 4L and the 300m 4L IS on a 40d and was pleasantly surprised. Was not expecting much from this converter. Shot some baseball and softball pictures over a sunny weekend and was able to get some good shots of the infielders and outfielders. No problems with autofocus. However, there was slight loss of sharpness, but nothing that cannot be photoshoped.

Merchant response: On the converter's product web page we say, “Teleconverters are not recommended for lenses wider than 50mm, e.g. 28-105mm.” So the 18-55 will not work.
In addition, the customer’s lenses are EF-“S” lens and will not work on non-supporting converters or older digital camera bodies.
