The Sigma 2x EX APO Tele Converter for Canon (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 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.

Note: Sigma APO Tele Converter 1.4x and 2x are dedicated teleconverter lenses. Due to the high optical quality of this teleconverter, this item will only fit and work with a select list of lenses. Please click here for a  compatibility chart of all compatible lenses.

The DG denotes an added coating that achieves the best color balance while cutting down on ghosting caused by reflections from the digital image sensor.

    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.

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

    With the sigma lens that I use with this teleconverter it doesn't auto focas but I knew that when I was ordering it. Not one complaint I can come up with at all. Works great and extends my 150-500 out to 1000mm!!! Can't even come close to 1000mm lens for less than $10,000.

          This converter will be used with An EOS T2i and Sigma 120-400 lens. It will require a bit of a learning curve. Pictures shot thusfar show very good quality.

                      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.

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

                                I bought this to use on my Sigma 120-300mm f2,8 S series. Images are sharp and focus is still very fast when using the Sigma 2x TC.

                                  The 2x teleconverter works well with my 70-200 mm 2.8 lens took it on a trip to Wichita Mountains used it and was impressed. Does lower your aperture as described in instructions. Cannot be used with anything other than Sigma lenses

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

                                    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!!
