Sorry I don't know since mine was purchased for my nikon 70-200 f/4. The internal diameter of mine when closed is 67mm.

I would ask DSLRKIT this question. I can't believe that anyone here has made the experiment unless they own both the Canon EF 70-300 is ultrasonic AND the Nikon 70-200MM F/4. Since DSLRKIT is both the vendor and manufacturer of the ring, you can contact them via normal Amazon channels. Please post their response back here so that others will know.

This tripod mount ring is only suitable for Nikon AF-S NIKKOR 70-200mm f/4G ED VR lens

Yes I use it on my 77 and it as good as canon 100mm to 400mm lens which i use it on my 5d

Yes, it will, I use it with my Canon 5D Mark III and a 70-200. Please make sure you have the proper attachment piece for your camera. I did use a cheaper tripod mount with ring and it broke. Use the Black Rapid attachment pieces.

D. Schultz has the right answer. The EF 70-300 will not accept this extender. Even if it did, the 2X extender adds two stops to the lens. In order to keep auto-focus a f/5.6 or faster lens combination is required on a Rebel camera. This extender is mostly for use on a f/2.8 or faster lens.

Yes, this lens works on an EF mount, compatible with a 70D and it is designed for a crop sensor camera, which the 70D is.

It will work with the 7D. It works best with EF equivalent lenses and not so much EF-S lenses in my experience. Even with the EF lenses, such as my Canon 100-400 L it works OK at 100 but I need to manual focus at 400. It works OK with my Tamron 70-200 f2.8. Also works fine with my lower focal length zooms. I don't have any primes to test it with.

According to http://www.overclock.net/t/1259989/canon-t3-question the T3 doesn't have a 3.5mm input, so the microphone would not work.

It doesn't work with the Canon 300 although the ad says it does.It appears incompatible with the camera. Beware

I recently purchased a D-3100 and have had no problem using the Sigma EF-610 flash on it. Works great.

Hi Christina. Yes, the EF 70-300mm f/4-5.6L IS lens works perfectly with the Canon EOS-70D camera and the recently released EOS-7D Mk II as well. It is one of my favorite hand-holdable lens Canon makes. Visit my website to see photos taken with this lens.

No, this one is for Canon FD lenses (old ones 70's I think). You need one for EF lenses.

I don't see why it would not work on the Canon 70D. It works on my Canon 60D.

I use mine on my Canon 100-400 and am very pleased with the results. I'd suggest that you first visit a local camera store andf ask if you can try it.
