Will this work on a Cannon T3i?

Yes, but you will still need to buy the adapter (http://www.amazon.com/Celestron-93625-Universal-1-25-inch-T-Adapter/dp/B0000665V6/ref=pd_bxgy_p_text_y) if you are going to use it with a Celestron telescope.

Absolutely, I've used it on many Canon cameras myself including the T3i. This is designed for any Canon 35mm lens mount so that still includes there past and present lines from I believe 1985 if I'm not mistaken. I actually work as a Canon Rep.

It works just fine on my t1i. As they are both EF mount cameras it SHOULD work. My only concern would be clearance to the mirror in some very rare cases. I doubt you will have a problem.

It should. It's a universal mount and I've tried it on a T3i and a Nikon. Hope that helps.

Haven't tried on T3i, but there is no reason why it shouldn't. It works on my 5D Mk III, 7D, and 70D.

No, the connections aren't oriented in the correct direction. Search on "canon t3i battery grip" and you'll find one's that will work on your T3i.

Yes, it would work well on the T3I. EF lenses work with all canon models.Good lens.

Hello,Yep this will work on your T3i. The mounting interface is compatible. (EF). As far as performance goes its a great lens all around, I am sure it will look spectacular. One thing to consider is the fact that the T3i has a cropped sensor. Cropped sensor DSLRs have a native 1.6X multiplier so is not going to really be 17mm at its widest... more like 27mm - 64mm. In addition to this, you will probably experience a bit of vignetting at 17mm as the lens is built to work on a full frame sensor. Hope this helps!

I am not entirely sure but I would assume so. It works great for the Cannon T3i Rebel. As long as the sizes are the same you should be just fine. It is the HC so it can hold the good quality images rather than the ones that are not.

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

Yes they will work on the canon t3i as that is the same camera we have ,you have to take into account the lens size(most of ours are 58mm)an get the correct size for yours.

I have a t3i and it works with any lens that will fit on it. Excellent quality.

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

Yes this adapter works really well on My Canon T3i and your camera uses the same lens. Enjoy!

We have used it on our t2i's with no problem whatsoever, so I would assume that it would work fine for a t3i.

Not really sure... You would have to look that up. I used it on my old Canon t3i & also my new Canon 70D. And it works great on them

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

I have a canon T3i rebel and it worked... but I have not had any luck since the first time I used it. I have changed batteries, still does not work...

I am not familiar with the Canon t3i but if it has a "hot shoe", my guess is that the ring flash would work. Although the unit is made by Polaroid, it works with my Nikon DSLR's.
