Will the auto focus work on a EF70-300mm f/4-5.6 IS USM lens on a Canon t3i?

It works for me on both my 70-200 f4L IS and Tamron 70-300 IS. I don't own the Canon 70-300, but I'm sure it will function for you just fine. It works for me, functionally, the same as these lenses do without the TC. I like it.

You should check with Canon, but I believe the lens will work with a Rebel T3i as the IS function is in the lens.

I'm using this with canon ef 85mm f/1.8 USM and canon ef 35mm f/2 works fine even with auto focus just a little bit slow on focusing so mostly I use manual focus also worked with sigma 18-250mm

No. The t3 uses the eos mount system, and will accept any canon ef/ef-s lenses. If you'd like to use fd lenses, you may purchase an fd to eos adaptor on eBay for as low as $30. Hope this helps.-Aaron

The Canon T3 Camera (Canon's economy class) DSLR with standard KIT 18-55mm Lens is of lesser quality Lens than their "EOS Rebel i" series (T2i, T3i, T5i, etc.), with their EF-S (Electronic Focus Stabilized) Lenses. However, the Sigma "AF" (Auto Focus) Series Lenses made for Canon products are essentially compatible with all Canon Cameras that use the EF-S type Lens mounting system. Make certain that the Sigma Lens 18-250mm you chose is the "AF" (Auto Focus), EF-S type for Canon. If you are still skeptical, send a note to Sigma Support, and they can provide absolute confirmation. One of the Lenses I utilize is a Sigma 18250mm "AF" on a Canon T2i, and Canon 60D. P.S. Just as FYI, the Canon 60D Camera is becoming a bit dated (some 3yrs. old since its initial release), but is still produced. Although the 70D is the newer version, and other makes/models have more features, the 60D is a powerful very versatile DSLR with lots of flexibilities, and provides excellent imagery results.

will this work on a canon ef 70-300 1:4 5.6 is usm or a ef 240105 mm 1:4 l is

Yes, I am using it with the "EF 24-105mm f/4L IS USM" lens. Keep in mind that autofocus does not work as your lens will keep searching for the focus and it will not find it, so you must use manual focus with it. When you take pictures with this extender, you only have a few inches from your subject before it loses focus.

I've had this lens for several years works well on my Rebel XS i think it should work fine on your Rebel T3i. the only issue that i've had with the lens is i got to close to something and ran the lens into something rigid and messed up the autofous . but the manual focus still works fine . and the auto focus was a bit iffy for macro work any way in my opinion.

I used this with my 55-300mm lens and it worked, both with my Nikon D7000 and the D7100. I prefer to use the manual focus instead of the auto focus. Automatic focus seemed to have difficulties at times, depending how far I zoomed in. As far as the 18-300 lens, I don't know but I assume it to be similar to my 55-300, so my belief is it should work.

Yes. I own the T3i myself, and like all the other Canon EOS DSLRs, it has an EF/EF-S lens mount. This is an EF mount lens, so this is supposed to work with ALL Canon DSLRs and SLRs (even the full-frame digitals).

All EF lenses work on EF-S cameras. Be aware the T3i has a cropped sensor, so the field of view will not be as large as a camera with a full sensor. 17mm X 1.6 = 27.2mm on the T3i. If you want a wider FOV than that, get a lens with a wider FOV. Just be aware a , say, 10-17mm lens will probably have some distortion at the edges of your photo. A safe bet is to rent the lens first and try it out before you buy.

Hi, This lens as you says the D3000, D5000, D7000 in the series of camera does not work for the auto focus. And you can manual shooting. Thanks in advance.

The 70-300 lens is not autofocus. The 18-55 can be set as either manual or autofocus.

It works with the 7D, but I'm not sure about the lens. I have the EF100-400 and it only works on manual focus.

Just make sure your buying the right Canon Mount in this lense, One more thing, It's going to work but just in manul focus mode.There is another Tamron Model that has a Built in focus motor. The Tamron AF 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens for Canon Digital SLR Cameras (Model A17E)A little more expensive but with auto focus built in the lense itselfe.Sorry about my broken english.Regards.
