Is this compatible with a Canon T3i?

yes, but it's a pretty noisy mic and won't necessarily be a huge improvement over the t3i internals.

Yes. This is the cable that I frequently use for the Canon T3i and the T3 as well.

Yes it is compatible to your t3i. I leave it on my camera all the time and get some great shots.

It works well with my Canon EOS Rebel T3. Not sure if it works with the Canon T4i

I know this product work with my Canon EOS Rebel 60D 18 MP CMOS Digital SLR. I am not sure if it works with a Canon EOS Rebel T3i.

Like the other responses here I use the 5D series of cameras so I'm not sure if it will work on the T3I.

It works with my Canon T3 I, so I'm sure it would. It's just a regular plug in like alll of the canons have.

I'm not sure but I bet you can check the Canon website. It does work with my Canon EOS Rebel T3i.

I should work with the Canon 3Ti. I have the T1i and it works with mine. I don't think Canon changed that much between the two cameras for it not to work. The all can use the same Canon Flash, and the same lenses, so I would assume that it would also work with the Canon 3Ti.

I have tested only on 60D, but to me it looks like The T3i has the same mini jack, so it should work.

no this is Nikon mount but Sigma has one made for Canon also and it will fit on T3I

It works with the Canon T3i lens perfectly but I don't know about any other cameras.

it does NOT fit the Canon T3i. which is what I bought it for. So I just ended up super gluing the rubber peice to the eye peice that came with the camera.

This lenses does say canon on the box. So I don't think it's compatible with that camera but it works amazing with. My canon t3i.

Both the T2i and T3i use the same battery, so it should be compatible. The one I got is a 5 or 6 foot cable. Beware though, i got two of these that were import models I wasn't comfortable with. The battery was a super tight fit and the full light was always on. I suspect they were forgeries. Returned those, and the third one was still not as good as the original that came with my camera, but the battery fit correctly and the charge lights behaved as the original did.

I've been using it on my T3 for a few months now. I don't see why it wouldn't work on a T3i.

I believe so. Have one on a T1i and one on a T3i. Be certain and speak with Canon prior to ordering.
