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.

First Impression Good

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

Just purchased this item. Have only used it twice. I am happy with the purchase. Know that there is no auto focus when using with the 50-500 lens. A tripod a must. I am an amateur photographer.

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

    I love taking pictures of soccer games. This little add on to my 70-200 lens made the games much better. While editing the pictures found much less need to use CROP.
    The only drawback is I loose the f2.8 which for what I am using it for doesn't hurt to bad, but I have not taken pictures under the light yet.

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

      I have switched over all of my kit lenses to Sigma Glass. People tend to sleep on Sigma lenses. I have found them to be very good, especially the Art series. I purchased this converter to go with my 70-200 lens. The overall build is solid as well as the function. Yes, I do loose a few stops, but getting that much closer without having to buy more heavier glass was worth it. Focus is still pretty quick, bokeh is still there (2.8 to 5.6) and I am able to get up close in personal with wildlife at the zoo from a safe distance.

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

          Received this as a gift. I am basically using it with my Sigma 120-400mm Telephoto Lens to shoot wildlife. I was well aware, when I started using it that there would be a loss of F Stops and no Auto Focus. I am fortunate to use this teleconverter with my Canon 6D as the pictures are awesome when shooting with high ISO settings. So far I have been blown away with the quality of this teleconverter. My pictures are sharp and well exposed. Considering the price of a high end telephoto lens, this piece of camera gear more than does the trick. I HIGHLY recommend this product.

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

            I have gotten back to birding and wildlife recently when I bought the Sigma 150-500mm and although I was very happy with that quality of this lens, there was always the Egret and Blue Heron that were not willing to get any closer to the deck I shoot from.

            The addition of this extender now gets everything twice as close for a very reasonable investment. You may want to know if you can put your other lenses on it, if they are not on the list of compatible lenses do not expect it to happen but since I bought it specifically for the Tele-zoom, I was not concerned.

            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.

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.

                            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.

                              Use with 150-500 lens, tripod or monopod.

                                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.

                                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.
