The Tamron SP AF Pro teleconverter features improved optical construction, and is designed to be used with lenses that are f/2.8 and of focal lengths of 90mm or greater.

The 1.4x teleconverter (also known as a tele-extender) will multiply the focal length of the existing 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.

This teleconverter is not recommended for lenses wider than 90mm, e.g. 50mm, 28-105mm, etc. However, full AF operation is still 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.

Note! When used with lenses with smaller maximum apertures (f/4 and f/5.6, for example) there will be little difference in image quality as compared with the standard Tamron teleconverters. When used with lenses wider than 90mm the SP teleconverters can actually compromise image quality.

Pro-series teleconverters are specifically designed and optimized for use with ultra-telephoto lenses (above 200mm) to deliver maximum resolution, contrast and color rendition without degrading any aspect of the master lens performance.
Improved optical design of 4-group/5-element for 1.4x and 4-group/7-element for 2x. Relative illumination is significantly improved resulting in better overall contrast and resolution across the entire image field.
Multi-coated elements result in crisper images.

    I purchased this teleconverter to use with the Canon 100-400 lens on a 1D Mk II for stationary subjects in good light at a distance. It is an excellent little tool. I was a little skeptical about getting the Tamron at first over the Canon, but the $$ difference was significant, and I thought I'd give it a try. The image quality is very good. I was shocked to find that the autofocusing speed with this teleconverter and the 100-400 in good light on the 1D Mk II was actually fairly good. I was able to capture birds in flight with the teleconverter on at full zoom! On the 70-200mm f/4 IS, this teleconverter shows nearly no loss of image quality over the lens bare. I use this attached to the 70-200mm f/4 IS and extension tubes for macro work, and the combination performs very well.

    The caps that come with this teleconverter are cheap and seem like they might crack at any time. You should pick up a set of canon caps instead for this, and you'll be set to go! It will save you money and works very very well with minimal loss of image quality!

    You give up a bit of light (compensate with ISO) and a bit of contrast (correct with software) but it does provide further reach, as intended. The price is right. I would not buy a longer lens for a once-in-a-while use, so this is a nice solution.

    The quality, as I have observed, is fine. Wolud I recommend it? Yes, with qualifications on personal preferences.

    I give it a 3 because it's got to work for someone.

    I bought this 3 days ago. Will be returning.

    Doesn't work on my 7D with my 70-200 2.8 IS USM II. Used a Canon 1.4X III last week with my 70-200 2.8 and a 300 f/4L IS, worked amazing - both (super sharp). Don't know what I was thinking. I was told this would work. I'll be buying the Canon 1.4X III instead. Fork out the dough.

    Double Check before you BUY !

      Comments about Tamron 1.4x SP Pro Teleconverter for Canon AF:

      I purchased this for wildlife photography, shooting auto racing and air shows. The reason I looked at The Tamron over the Canon was the price difference and am happy to say that it was a wise choice. It works great on all my lenses ( Canon 300mm F4, t Tamron 70-200mm F2.8 and even my Canon 50mm F1.8 )

        Comments about Tamron 1.4x SP Pro Teleconverter for Canon AF:

        I bought this for use with my Underwater camera system. I will be using it with the Canon 100mm f2.8L and the Canon 8-15mm lenses. This teleconverter doesn't have the rubber rings (which make them incompatible with many lenses) that the Canon TC has. All of the auto focusing functions seem to work properly. Keep in mind that you will have to add extension rings to your ports when using teleconverters. Also your focus & zoom rings will need to be changed. I found that the focus ring for the 60mm Canon macro lens works great with the 8-15mm/1.4 TC combination in my Sea & Sea housing.

The light and the colors of my photos subjects are very close to the live originals. I am planning on using it with my new telephone zoom lens as well.

                  2. Attach to the camera as usual

                  It is light and small, and hardly noticeable

                  you lose 1 stop ( your F4 lens is now F5.6 )

                            Comments about Tamron 1.4x SP Pro Teleconverter for Canon AF:

                            I purchased this teleconverter to use with the Canon 100-400 lens on a 1D Mk II for stationary subjects in good light at a distance. It is an excellent little tool. I was a little skeptical about getting the Tamron at first over the Canon, but the $$ difference was significant, and I thought I'd give it a try. The image quality is very good. I was shocked to find that the autofocusing speed with this teleconverter and the 100-400 in good light on the 1D Mk II was actually fairly good. I was able to capture birds in flight with the teleconverter on at full zoom! On the 70-200mm f/4 IS, this teleconverter shows nearly no loss of image quality over the lens bare. I use this attached to the 70-200mm f/4 IS and extension tubes for macro work, and the combination performs very well.

                            The caps that come with this teleconverter are cheap and seem like they might crack at any time. You should pick up a set of canon caps instead for this, and you'll be set to go! It will save you money and works very very well with minimal loss of image quality!

                              Comments about Tamron 1.4x SP Pro Teleconverter for Canon AF:

                              I use this teleconverter with a Sigma 150mm f2.8 1:1 macro lens. I am very happy with the results. The image quality is still outstanding with this TC/lens combo and the autofocus will work in most situations. On occasion I have to manually focus close to the subject to get the autofocus to engage but I have not found that to be a problem overall. I primarily use this combo for small insect and wildflower shots.

                              I would not recommend this TC to be used with the Tamron 200-500mm lens. I have tried this combo and find the results to be simply fuzzy. I think cropping with the original lens only will give better results than with this TC. And keep in mind this TC is not designed for the Tamron 200-500 f5-6.3 anyway.

                              Bottom line I can recommend it but only for lenses that it is designed for.

                                    Works as advertised. I'm using this to extend my 70-200 f2.8 Tamron. I haven't experienced any AF problems, most of my use has been outdoors.
