Product Highlights
  • Compatible With EF Lens Mount Only

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 2x teleconverter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300mm lens will effectively increase the focal length to 600mm. A lens set to f/2.8 will now be f/5.6.

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. This teleconverter is compatible with the EF lens mount only--not compatible with EF-S lenses.

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.

      Using with a Canon 60D and Canon EF 70-300mm lens.
      Knowing going into it that this combination would not work with auto-focus ... it actually does work at times, but I use it on manual focus and am very happy with the same quality shots that I get without the converter, but now have the ability to get much closer shots of birds and other wildlife. Also, took some great shots of my Leonbergers (dogs) romping in the back of a field.

      I have successfully purchased many items from B&H in the past and was very satisfied, but this purchase was a disappointment. The detailed description stated it will fit a Canon EF-S lens. Once received and opened, this teleconverter would not connect to the lens. A very responsive customer service offered a return, then connected me with a sales representative. The sales rep reviewed the issue, placed me on hold, and called another distributor. Upon his return, he informed me this other distributor confirmed there is "NO" teleconverter that interfaces with the Canon EF-S lenses. If you have EF-S lenses this will not work, despite the detailed information listed on this website.

        Comments about Tamron 2x SP AF Pro Teleconverter for Canon EOS:

        If you can get by the fact AF will not work unless you have a f2.8 or better lens, this is a good value compared to purchasing a 600mm lens.

          Comments about Tamron 2x SP AF Pro Teleconverter for Canon EOS:

          As with some other reviewers my budget couldnt stretch to a 400mm lens so the teleconverter option was the way I went. In combination with a Tamron 70-200 2.8 the teleconverter has worked surprising well under a variety of light conditions. AF works just fine with the stated lens on a Canon 40D. I'm very happy with the purchase.

            I used this product with a 100-400 mm zoom lens set at 400. It performed admirably well. In bright sunlight there was no loss of definition. It didn't do as well in lower light, foggy conditions. But, the pictures were still quality.

                I own a Tamron 70~300mm zoom lens and wanted a longer focal length but can't afford a new lens right now. So I bought the Tamron 2X SP AF Pro converter for my Canon 60D body and it exceeds my exceptions although I had read some reviews that the AF didn't work for some but so far its worked flawlessly for me.. I did lose a couple of F stops but for the price I can't beat it. And for those who can't afford another lens it's a great alternative. I've purchased several times now from B&H and highly recommended them I'll continue to buy from B&H for my photographic needs..

                  This teleconverter just made my 75-300 lense a big boy 600 mm lense and I can play with the white lense guys! I can also get macro macros with my 100mm macro lense. Best of opposites. Saved a lot of money and not nearly as heavy to carry than buying 2 white lenses.

                    I will use this lens to extend my 100-400 Canon lens as well as a couple of other zoom lenses that go to 250 mm.

                    The great thing is that I can actually get closer.

                    Not so great is the need to focus manually. I knew that before I bought the lens and do a bit of shooting mirror up when I generally focus manually anyway.

                    For the price it is an excellent compromise.

                      This is an excellent choice for the people that don't want to spend a ton of money of a 2x tele converter. I use mine on a RED Epic and Canon DSLR and it works phenomenally. I do notice that the picture isn't quite as sharp when using the focus assist but zoomed out you can really tell at all. The VR works perfectly as well as the iris control. I am constantly pleasantly surprised by Tamron and will continue to buy their product.

                        I bought the teleconverter to increase the focal length of my 70-300mm telephoto so I could take pictures of the lunar eclipse a few weeks back. Unfortunately, my area was clouded over, so I never got a chance, but I did take a few shots the nights before. I was very pleased with the results (image below)...nice detail with visible craters, much better than using my 70-300mm on its own.

                        Two cons...
                        1. It doesn't seem to auto-focus, but this isn't a dealbreaker for me. I tend to use manual focus most of the time anyway.
                        2. You lose two F-stops.

                          I read the reviews and bought the teleconverter for my Tamron 70x200 F2.8 lens. It focuses quickly on AF and is great in manual as well. The clearity was better than I had expected and saved me from purchasing a 200x400 lens.
                          I have not found any down sides to this teleconverter.

                            The great thing about buying this converter over the Canon 2x is that this one works with both my 70-300 and 70-200. Now on the 300mm you pretty much have to manually focus but for what and how I shoot that's ok. Auto focus on the 70-200 works just fine. I've not had any issues. I love the extra distance I can capture now? Just used it again today at a nature center preserve and it really fit my needs. . I would recommend it.

                                  Despite all the posted reviews describing the compatability of this extender with the 18-270 Tamron lens, it fails miserably in that the autofocus feature of the lab ceases completely with the extender. You are comdemned to manual focus!

                                    Using with a Canon 60D and Canon EF 70-300mm lens.
                                    Knowing going into it that this combination would not work with auto-focus ... it actually does work at times, but I use it on manual focus and am very happy with the same quality shots that I get without the converter, but now have the ability to get much closer shots of birds and other wildlife. Also, took some great shots of my Leonbergers (dogs) romping in the back of a field.

                                      coupled with a macro lens this teleconverter does what I need it to do...
                                      expecting it to autofocus is a fools dream...

                                          I have successfully purchased many items from B&H in the past and was very satisfied, but this purchase was a disappointment. The detailed description stated it will fit a Canon EF-S lens. Once received and opened, this teleconverter would not connect to the lens. A very responsive customer service offered a return, then connected me with a sales representative. The sales rep reviewed the issue, placed me on hold, and called another distributor. Upon his return, he informed me this other distributor confirmed there is "NO" teleconverter that interfaces with the Canon EF-S lenses. If you have EF-S lenses this will not work, despite the detailed information listed on this website.

                                              I mainly use the teleconverter for sports. It performed just as I expected at a golf tournament and for taking shots at the kids baseball games. Auto focus works to some extent but it performed best in manual focus mode.

                                              Own a tamron 70-300mm and it works great on this lens. Wouldn't work with my Canon 18-135mm ?? 600mm is not sharp at all, auto focus is useless. I find I use it more in the 350mm to 5000mm. Remember it only doubles the quality of the lens you're using.

                                                Comments about Tamron 2x SP AF Pro Teleconverter for Canon EOS:

                                                I wanted to be able to take photos of the alligators and other wild life in the State Park near my home here in Sarasota Florida. I felt that with the telephoto lens that I have; I just was not getting the close-ups that I wanted. Other than getting closer to my subjects which are mostly alligators (Do not recommend getting close to alligators) or buying a super telephoto lens.
                                                I decided on the cheaper and safer route and bought this teleconverter.
                                                I am very happy with my purchase. I have used it quite a bit and have not been disappointed.
                                                I do not have anything negative to say about this product.
