To be honest, I really don't know as I have never mixed makes. I would advise asking a specialist supplier as this should give you a knowledgeable and accurate answer. Best wishes, Ian Giles

Don't count on it. These are designed to work specifically with Canon EF mounts. Nothing else. Call Sigma and ask.

Yes it will, This lens is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L. Additionally, please see the lens and/or camera body manual for full compatibility information with the Extender EF 2X III.

Well mine works perfectly with the Sigma 1.4X teleconverter and if you check the Sigma compatibility page here: http://www.sigmaphoto.com/teleconverter-compatibility, you can see it will work with the 2X. Hope this helps.

Looks like that one is for Nikon mounts, so I would say no. Try this one instead: http://www.amazon.com/Sigma-55-200mm-Telephoto-Digital-Cameras/dp/B0001VQ12Y/ref=sr_1_1?s=electronics&ie=UTF8&qid=1392059621&sr=1-1&keywords=sigma+55-200+canon

If you go to the canon web site, go to the extender 1.4 description and they list the lens compatability list. You can find out your answer there.

To be absolutely sure simply call Canon Tech Support and ask the question. Canon will want to know your exact lens information not simply a 70-200mm lens. Obviously I own this extender and other photographers have tried to use this extender with their lenses, in this case both the the lenses were "L" series Canon lenses and in one case the extender would not couple with the lens and in the other case the extender did couple to both the camera and lens but the autofocus feature did not work. Canon has the answer for you, call 1-800-652-2666

First, let's talk about physical requirements. The 2x extender will work on ANY Canon model that accepts EF type lenses. This includes the 60D. However, you need to go to the Canon website and check the compatibility chart for this extender with the various Canon lenses. Some lenses will physically not work with this extender because the rear element of certain EF lenses is too far back in the lens mount and will not allow it to connect to the extender. The 2nd problem is light. The lens should be a minimum of f/2.8 as you will lose 2 f-stops of light with the extender. Anything less than f/2.8 may cause your camera to NOT autofocus. It will still work but you will have to manually focus the lens. First, let's talk about physical requirements. The 2x extender will work on ANY Canon model that accepts EF type lenses.

This lens works fine on a Canon 600D. Just keep in mind that this is an EF lens, so with the cropped sensor in 600D, it is effectively an 80mm lens.

I dont have the same body and lens you have, but I can report success with a 70D body using a Canon 70-200mm f/2.8 using this extender. The fstop jumps to f/5.6 and the autofocus still worked perfectly through the next 2 or 3 stops.

I use this adapter with lenses that already have aperture rings and it works just fine. You just need to keep the aperture on the adapter open all of the way. It might be beneficial to just go ahead and buy this adapter instead of a passive adapter in case you want to invest in newer canon glass.

Not sure, I would thin the sigma web site would tell you. It works on the 20D, 30D and 60D

Funny you should mention that! I got the converter for my (Canon Mount) Sigma DG 70-300 mm lens. The converter fits the camera nicely but t didn't fit the Sigma lens! Waiting for an answer from Sigma. I can tell you this: if the lens element closest to the camera mount is flush or protrudes from the lens it WILL NOT fit the 2x converter.

Can't say. It was not compatible with my Canon zoom. It worked on my Sigma lens, but the resulting image was poor. When I compared the 2X converter image with the non-converter image blown up to the same size, the non-converter image was sharper.

It will fit but in all honesty this is not worth your time or money for an extender. it is cheap and does not have functionable use. Save your money get an L series Canon lens and buy the Canon 1.4 extender you will produce quality pictures. when it comes to photography don't settle cheap. i have learned the hard way with buying cheap and instantly regretting it.

Yes I did. I believe my shots are in the customer photos. I did not use an extender, just maxed out at 400mm though I didn't calibrate the sweet spot for the aperture for maximum clarity. I shot both handheld and tripod and I was very amazed by the handheld quality. I was very happy with the results.

None of the EF-S lenses will work with the 1.4X or 2X extenders. Not Bower or Canon. They will not fit the extender, the lens glass hits the extender glass.

I haven't tried it with an extender, but I don't think it's compatible. This information comes from Canon: "This converter is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L."
