    Sigma 876101 reviews

    APO Teleconverter 2x EX DG for Canon EF is rated 4.4 out of 5 by 55.
    Rated 5 out of 5 by from Great Addition to my Camera Gear 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.

    Rated 5 out of 5 by from Teleconverter Works great Will get full use when Christmas comes. USED WITH SIGMA (for Canon) 150-500 Lens) However, I did test when I got it worked great easy to focus sharp pictures at all distances. Though its Manual Focus for Normal DSLR system, I did notice it would autofocus on my Canon EOS Rebel using Live Mode. The pictures came out sharp even in an indoor environment with limited light. I varied ISO and apetures to see how well t it would function in low light and found it to work well with and without flash. I did notice I would see objects in view that previously were not because of the highr magnification; got to get use to that.

    Rated 5 out of 5 by from Great addition to my 70-200 f2.8 I own a Canon 60d with a Sigma 70-200 f2.8 lens. I take a lot of sports shots and videos where I'm quite far from the subject (ie kitesurfing, etc.) I was hesitating between buying that multiplier or a new Sigma 150-500. I figured that I wouldn't carry another big and heavy lens in my bag anyway so I opted for the multiplier. What a great choice! The lens goes to f5.6, autofocus works well even in low light situation. The zoom is incredible (640mm in my case) and I'm still able to shoot hand held in relatively low light situation with the IS on (of course it's better on a tripod, but still, I was impress at the clarity. I'm really looking forward to test my new setup during the next kitesurfing session. A perfect buy for my needs.

    Rated 5 out of 5 by from Well worth it! 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.

    Rated 4 out of 5 by from Better then Expected I have to say the Tele Converter, was much better then expected. I have paired it with my Sigma 70-200 lens for the rare times I need that little extra reach. Its use will mostly be for shooting the rare wildlife photo, and at event shows where getting close to the subject is not possible. The converter causes very little loss in the color or clarity of the lens. And at F9 or so images are amazingly sharp. I contribute the sharpness a great deal for having a steady tripod.

    Rated 3 out of 5 by from No opportunity to try Unfortunately I never got to try this converter. I own 2 copies of the same lens that were supposed to be compatible but weren't. The converter fit my camera but did not fit my lenses. I am in no way bashing the product and the customer service was great in handling the return, thus the 3 stars for that effort. My only gripe was losing the S/H for the purchase and return. I think Sigma should have to make good for that since it was, obviously a bad copy,but that is an entire different issue. It has not dampened my willingness to try again and when I get one that finally fits I'll be happy to write a raving reeview.

    Rated 4 out of 5 by from Close just got closer 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.

    Rated 5 out of 5 by from Awesome! 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.
