Will this work with my Canon 5D mark II and a Canon 50mm 1.4? I just realized the extension tube says EF-S?

IT works with my canon 5D mkII and my 50ml EF 1.4,auto focus and aputure. You may have to play with the alignment for the tubes connections if you stack them. All work well in manual mode.

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

The ST E2 works flawlessly with My Canon EOS T2i. Sorry, I don't know if that will work on the 5D MKII.

I've used it on my T3i, and I don't think canon would have changed their ef mount standards, so yes it should work. I have not tried it with EF-S lenses but the telltale white dot is on there.

Yes - works with all the ef and efs lenses I've tried it with and is very solid. Build quality might not be quite as nice but it's a lens adaptor so I don't really care too much.

Yes. This will work on any canon camera with the EF mount. Keep in mind that it does not have a smart-mount, so auto focus will not work, and you will not have any control over shutter speed in most lenses.

Works with canon EF-S type lens and cameras that use EF-S lenses. Not sure what yours is.

I have a 5D mark II, they work just fine with it. Charges canon and wasabi batteries equally well. Prefer canon change from blinking to solid lights when charged, to wasabi change from red to green lights, but can easily put up with it for the price.

Yes it is compatible with all Canon EF and EF-S mount cameras... I own a EF 70-200 f4 L and use it on my Canon Rebel XSi (450D) and my 60D. Both of which use the EF-S mount used on your 550D.

I use a Tamron pro 1.4 extender. Ability to use extender depends on the lens. Most of the EF-S lenses cannot mount on a converter. I use the extender with a 80-200L f4 lens. It will not auto focus on a f 5.6 lens. Hope this helps

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.

Look up the specs on your camera. It must say "eg-s". If it only says "EF" then no. That was my issue and I had to return the lens.

It should be compatible with the Canon 5d Mark2. It is compatible with the Canon Mark3 and the Canon 50D.

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).
