Extend the reach of your telephoto lens with this APO Teleconverter 1.4x EX DG from Sigma for Canon EF-mount cameras and lenses. This model will increase the focal length by about 40% while only losing 1 stop of light in the process. It also retains communication between the lens and camera, allowing users to use automatic metering and autofocus. Additionally, this teleconverter has a multi-layer coating that reduces flare and ghosting for sharp, clear imagery.

For compatibility please see this chart from Sigma which outlines which lenses can be used and the various functions possible with each.

    Sigma 824101 reviews

    APO Teleconverter 1.4x EX DG for Canon EF is rated 4.6 out of 5 by 33.
    Rated 5 out of 5 by from Works well with Sigma 50-500mm lens I bought this to extend the max zoom on my Sigma/bigma 50-500mm lens, so I now have an equivalent of 700mm max zoom. As indicated by Sigma, I lost autofocus ability at normal shooting f-stops, but I have been able to use it effectively with birds in flight (hawks and eagles) at quite some distance with good results using manual focus. The combination I have results in a hefty rig, but if you approach it like aiming a shotgun, it becomes workable. The teleconverter itself is great and will be great with any lens you use it on. It is working well for me pushing the limits of reasonable optics and hand-held photography. Image results are pretty good, especially with the types of images I'm shooting.

    Rated 5 out of 5 by from Great add on to my 70-200 For the price it can't be beat. I am not a professional by any means, so when it comes to new gear I'm always looking for quality without breaking the bank and Sigma has never let me down. It feels very durable and very well made. I like the extra reach it gives my 70-200, and the AF to me still seems fast. It doesn't seem to lose any sharpness, but I haven't really had it long enough to fully say either way. Only time will tell since I've only used it outside in direct sunlight so far. It was between this and the 2x but I didn't want to lose that many stops with the 2x so I opted for this one.

    Rated 2 out of 5 by from Not reccomended... Serious vignetting when attached to a 70-200 f/2.8 lens. I am shooting on a full-frame 5D. I get better results shooting at f/2.8 @ 200mm without the converter and cropping in the image to a 280mm than I do with the converter and actually shooting at 280mm f/4. The glass used in this converter is MUCH smaller in diameter than the Canon version of the same product. Think half-dollar size vs. quarter size. No wonder the Canon version costs so much is simply just a superior product!!

    Rated 5 out of 5 by from Tack sharp and works as advertised Works great with my Sigma 70-200/2.8 EX APO lens, increasing the focal length with almost no visible image sharpness degradation - even at wide open aperture (F4 in my case, since you do lose an F stop with the converter attached). Little impact on autofocus under most lighting conditions. Not noticable on my APS-C body, a little on the 1v. High quality construction made to withstand tough handling, the matte finish matches the matte finish of the Sigma lens. Even though the picture looks like one overpriced single lens element, do not be deceived. This is a multi-elements precision lens attachment. Comes with a durable vinyl tubular case. Contact pass-through ensures all metering modes, auto-flash and autofocus work as if the lens is directly attached with my lens. Adds very little length to the whole assembly. Lend it to a friend who uses a Canon 20-700 F/4 IS and it worked perfectly with that lens. Fair price if bought new at B & H; and if you can get it for around $100 used it is a must-have great deal.

    Rated 5 out of 5 by from 1.4x DG EX APO Teleconverter by Sigma I use the teleconverter with a telephoto lens Sigma 70-200mm f/2.8 APO EX DG OS HSM. The photos are extremely sharp and the colors are not distorted. It is very easy to use and it should not be any problem to anyone. The telweconverter is an excellent quality and if used with lenses take one f step down. I do not have any negative comments and I do recommend the teleconverter for use with telephoto lenses.

    Rated 5 out of 5 by from Excellent - worth every penny I use this extender on my Canon EOS XSi with a Sigma 70-200 f/2 telephoto lens. My primary subject is little league baseball/softball of my children. The other parents have never seen photographs of their kids playing in the field like this lens takes. With the extra reach the extender provides you can get right in the glove of the outfielders and infielders. I'm selling the pictures as a fundraiser for the teams and the parents are just ga ga over the quality of the photographs of their kids. My photos have been in daylight so I can't speak to the loss of the stop the extender causes, but I see no loss of sharpness at all and no noise. I would highly recommend this extender to anyone photographing sports. The autofocus works great as the extender integrates with the Sigma 70-200 so seamlessly you don't even realize its on the camera.

    Rated 5 out of 5 by from Great Teleconverter I bought it for my wildlife photography and a second one for my wife and her birding photography. Fantastic purchase! Have not noticed the loss of an f stop and am amazed at the clarity of my prints using the extender. Mounting my lenses to the teleconverter took a little getting use to as you have to slightly extend any zoom lens you may use before connecting it to the teleconverter, but what photographs. On my 500mm lens it's like I'm standing next to the wildlife I photograph and still I remain 200 to 400 feet from them. GREAT, GREAT purchase!!

    Rated 4 out of 5 by from Perfect and fast delivery This teleconverter will only fit certain sigma lenses, and is perfect for my 150mm f2.8 macro lens. the quality seems very good.
