How well will this teleconverter work with the Canon 60D and a Canon 70-300mm IS lens?

I have a 5D mark ii and have used this with a couple longer L series lenses. I haven't noticed much distortion, but the photos seem a bit softer. Not enough to be much of a problem. Overall I like this product.

Since this teleconverter works with EF lenses only it will fit the 60D which is equivalent to 224-960 with the crop factor of 1.6. 70-300 x2 = 140-600 x1.6= 224-960. but at the same time the aperture will also suffer from f4 to f8 or smaller. I've used this for my 60D and to even get adequate shutter speed with the smaller aperture you have bump up your ISO by which the images then becomes grainy and doubling it with this converter makes the final image unacceptable. I don't recommend this teleconverter on an APSC sensor at the long end of a telephoto lens. I used a Tamron 28-300 telephoto with this converter and the images were horrible. If the lens isn't sharp in the first place this converter will magnify that flaw x2!

[fixed incomplete answer]This teleconverter should work, yes, but it will have a number of important drawbacks:(1) It change the effective aperture range of your 70-300 from f4-5.6 to f8-11 wide open. This will disable auto-focus on most Canons and the smaller apertures can make it harder to manually focus (at least with the optical viewfinder).(2) The increase in focal length can magnify any softness (typically, at the longest end depending on the quality of the lens) and may decrease the apparent effectiveness of IS image stabilization.

I read somewhere it does NOT work. I would not recommend this combination anyway fr quality reasons. It is a bad idea to use a converter for a wide-to.tele-zoom. Teleconverters are best for fast lenses (2.0...4.0) and longer focal lenghts (fixed or fast pro telezooms).

Rocky ... Good news! while I can't answer with certainty, the Sigma web site has a table for all their lenses including the 2X teleconverter and it's compatibility with your Sigma 70-300mm apo dg lens. I can also highly recommend calling and talking to a Sigma representative.

The teleconverter works best with F2.8 lenses. AF may not work well at higher F stops and you may need to go to Manual focus

I have the 2x Teleconverter from Tamron but i am not sure it is the same here. Mine is all black. I can tell you that I do use it with the same setup you have using a Canon 7D and the Tamron 70-200mm and it works just fine.

It probably will not work properly. Check the lens manual to see if it is compatible with a 2X teleconverter. It may focus manually but you will be disappointed with the results. The lens manual will tell you if it is compatible at all. The Nikon version of this lens will work and autofocus with the 1.4X teleconverter but results with the 2X are poor.

as long as the nikon camera has a t mount and the teleconverter matches that mount it will work together. The problem lies in the lens I am NOT sure if it would work. I know it works on lets say 50mm lens.

canon does have this teleconverter listed as a component that will work with the 100-400 lens

It works on my Canon 60D and there is every reason to assume it would on a 70D as well.

I haven't tried it on a 70-300, but I have used it on a Nikon 55-200 af-s lens and the pictures always come out great. The only problem, as others have mentioned is that the autofocus often gets jumpy, and in some circumstances it won't autofocus at all. If you are prepared to use manual focus you'll have no problem.

Hi,Yes, it will work with the 7D. ( great camera, I owned one.) If the Tamron 70-200 lens is a Canon mount and fits your 7D then it will work with the teleconverter.Happy shooting.

That is what I use it with. Works great with telephoto lenses. I use my 300mm F4 with it mostly.

I don't own a 60D or a 70D I have a t3i and it works great on that. My dad has the Canon 7D and he has the same timer shutter and it works fine for him. So I am guessing it would work

Big issue on using teleconverters is lighting. if you don't have good lighting then no. also the speed of your focus has an impact in performance. slow autofocus and you camera will hunt. I ha d a sigma 70 - 300mm lens and it did ok. but my tamron is so much better. especially with teleconverters. one thing the keep in mind. your f factor with change with these.so an f4 be much higher. hence lighting issues.I have even stacked them with mixed results.I have a nikon D3100 with 2 nikon lens, 18-50mm and 50-200mm, and a tamron 70-300mmand 2 of these teleconverters.

I have a D3100 and the teleconverter works but it is slow to focus. If I had to buy again I would not save the money and buy a nikon teleconverter it works better and faster.

It works on all my Canon crop frame cameras, from 20D to 40D to 7D, so it will work on the 60d. This lens produces good quality picture up to around 300mm, and since it does not have image stabilization, best to use either a monopod or tripod (heavier legs), else it's top heavy and unsteady. I hope this helps.
