Reading the comments here I can see that many people purchase this product without understanding it or even understanding their cameras. I have used this lens as an attachment to my macro lenses to get 2:1 magnifications without reducing my working distance. I have been very please with the image quality of my photos taken with this product, they retain sharpness and allow me to capture much greater detail in my macro photos. The converter is designed to be used on particular lenses, It will work with some lenses not listed on the charts that Sigma has available on their website, but it definitely will not work on all lenses so you should be careful in your purchase of this product. The 2X teleconverter will not only double your focal length but it also doubles your the f-stop as well so a f2.8 lens becomes a f5.6. This is a really important consideration when making your purchase because most crop framed sensors will not auto focus at f-stops smaller than 5.6 which means that many lenses will lose their ability to auto focus when using this particular Tele Converter. Many of the negative comments that I read here had the common theme of "no auto focus" that is not the fault of the Tele Converter but rather the purchaser did not understand what he was purchasing. For me this has not ever really been an issue as I have almost exclusively used mine for macro photography where I don't use auto focus anyway. I will say that it is designed to work on the sigma 150mm macro lens and retain auto focus but on my Canon 100mm f2.8 macro lens the auto focus really does not work well at all. I also have the same problem with the 1.4X tele converter on that same lens while the auto focus on my Sigma 180mm f3.5 macro lens works extremely well with the 1.4 tele converter attached. I only point this out to make the point that f-stop alone does not determine the compatibility of this product with any particular lens. As far as durability and quality I highly recommend this lens, but I also would recommend that if you have particular lenses that you want to use with it that you do a little research prior to your purchase.

Turn your 300mm lens into a 600mm.

I use this teleconverter with my Sigma 120-300 F2.8 lens and auto focus works and it focuses fast and brings objects much closer but as with most 2X converters the image quality suffers some, and that is why I only gave it 3 stars.

      I have been using this teleconverter with the Sigma 50-150mm f/2.8 EX DC OS HSM APO Lens for Canon. With my EOS 7D, I am getting 480mm @ f/5.6 and the camera body is well informed of this new setting. Great gear! I am quite willing to recommend it to anybody.

          Fits neatly on my Sigma 50-150 2.8. Focuses well and exceptable sharpness. Inexpensive way to get a 450mm 5.6 lens with decent performance.

            Used with the Sigma 150-500mm lens to reach out even further with great results. It's compact size makes it easy to carry and does not make much difference in the overall weight on my tripod.

              I bought this to complement my 70-200 lens for some action and bird photography. My early impression so far is absolute satisfaction. I cannot detect any compromise in performance of auto focus or picture quality per say. The added zoom capability paired with that makes this a no brainer for me at this price.

                Works great with extending the lens for better shots of Eagles perched high on towers near Lake George, Florida. Have to use manual focus, which isn't to complicated, and fairly quick to focus manually.

                  I picked this up at the same time as the Sigma 50-150 hsm os zoom and am very glad I did. So far I have not seen any cons with this extender besides a small loss of resolution but nothing that you would see on a 8x10 print.
                  On a Canon 70D the focus is still very good on the 50-150 with this extender.

                      I use this with my Sigma 70-200 F2.8 EX DG HSM and I am really impressed with the convertor. Obviously, you would expect to lose 2 stops but it is worth the risk. Keep in mind, it is to be used only with Sigma family of lenses.

                            I've used the teleconverter/extender with my Sigma 70-200 (2.8) for (daytime) baseball and for some wild animal photography. I've been impressed with both. Obviously, giving up two stops means there are some sacrifices (either with shutter speed or ISO), but for daylight work, I found it well worth it. The additional weight is noticeable, but not overwhelming, and on-off installation is quick and easy.

                                After reading all the reviews I went ahead and odered it. And WOW!! It works awesome!! I am pairing it with a Sigma 70-200mm f/2.8 EX DG APO OS HSM. I still have fast focus and great image quality. NOTE: you must use a good lens with this!! Your F/stop will go down!!

                                  Bought this for our trip to Africa, and it came in very handy, turning our 120-400 mm zoom into a 260-800. Great shots...great memories.

                                  Does all that I expected of the teleconverter. I have pics of the Empire State Building 26 miles away tha provide great clarity for the distance.
                                  One Item though the Data chart says only Manual Focus. I did an experiment and it Autofocused in my Canon T1i in Live Mode just fine.

                                    Comments about Sigma 2x EX DG APO Teleconverter for Canon:

                                    This was the absolute perfect thing for my 70-200mm Sigma 2.8 OS lens. As anyone with this lens knows, it has an extremely far minimum focus distance. This helped with some macro work and also gives me a 400mm lens that I can now use to shoot surf photography.

                                    For macro, I also added a Canon 25mm extension tube and it worked perfectly. I now get about 1:1.5-2 magnification. Same finish and build quality as all the other high end sigma products.

                                    I'm very happy.
