Will these work with Canon EF-s lenses, retaining aperture and autofocus control?

Yes. On occasion I get a lens error that can be resolved by turning the camera off then on.

The answer to your question is 'yes.' These tubes unlike some cheaper ones has an electrical connection which allows for retaining and setting apperture and use of autofocus. However, I have found that for precise focus shooting macros manual focus works better than autofocus.Chuck Scarcliff

Mine does on XSi. There is one vivitar set that does not but it is clearly stated in the site description. Aperture always works, autofocus works with moderate extension; however, manual focus is more likely to get the result you want. Also, a tripod and live view with magnification helps a lot.

if by the size you mean the front thread of the lens, yes it doesnt matter the front size, these go between the rear part of the lens and the camera body and they work with EF and EF-S lenses.

This converter should work on Canon EF lenses. Because of their protruding rear elements, I would expect that this converter will NOT work with EF-S lenses for crop body cameras. Caution - if used on a lens with a maximum aperture of f/5.6 or greater, AF will not work except on 1 series bodies and the 5D MkIII (if most recent recent firmware has been installed).

No auto focus control, even if you're using lenses with AF. (At least for the canon lens mount, though I expect all the mounts are like this). Also, iris/exposure control is limited on some lenses. Check their website to see what works.

Hi Dave, I can only vouch for EF-S lenses compatibility. Haven't tried it with a EF lens.

It worked well with my ef len but seems to cloud my photos with my efs lens. i have noticed many of the extentions say they will not work with efs style lens. good luck, and if it won't work at least Amazon is great about returns.

Yes.. your camera uses the EF and EFS lens.... practice your manual operation of your camera to get the best results... Happy Shooting

Yes. Any EF-S lens will work with a Canon SLR that has a smaller sensor (such as the T3i). They will not work with a full-frame digital SLR camera, such as the 5D or 6D. The lens is very nice, though it is a bit on the slow side (max. aperture of f/3.5).

EF-S lenses aren't just compatible with the Rebels but are also compatible with all other current Canon dSLRs EXCEPT the 1D and 5D pro lines. You can still upgrade to a semi-pro 50D or near-pro 7D or future equivalent and still keep using all your old EF-S (and EF) lenses. Even if you decide to go pro sometime later on, Canon lenses hold thier value pretty well (more so for the higher end lenses).

I contacted Adorama Camera and asked this specific question. The following is their reply:Should work, however please contact mfr @800 421-1141 to be certain I called the number and left a message, but unfortunately I haven't received a return call yet. My photography teacher has a set of these that he has let me borrow to experiment with, and his box, unlike the picture on Amazon, specifically states that they can be used with EF and EF-S lenses. I will let you know if/when I hear back from the manufacturer.

Hi, Deirdre! They are for different cameras - EFM - only for new Canon EOS M camera and EF lenses - for wide range of EOS cameras. You can use EF lenses on EOS M camera with special adapter.

"the sensor is designed to work with Canon's EF and EF-S lenses with a conversion factor of 1.6x"... Short answer, yes.
2095116
These lens are compatible with EF-S and not with EF. It won't work on FF cameras like 1D as the size is small.

Yes. To help you in the future, you have an "eos" , mount for your lenses. Anything that says eos mount will work.

You will be able to mount your lenses, but you won't get autofocus or aperture control. They will essential be manual focus, fixed aperture lenses, so you will only be able to shoot them wide open. If you have a Canon body you can "trick" the lenses into stopping down before you mount them using the DOF preview button.

Yes, but not all tamron lenses. They have to be compatible with canon EF mount.
