How will this extender work with Canon EOS 5D Mark III and Canon EF 100-400mm f/4.5-5.6L IS II USM Lens

Not well quite simply. The maximum lens aperture is not a small enough f/stop number, you will lose autofocus and unless shooting in very bright light on high contrast subjects even manual focusing may be difficult.

It will work well with the camera. I have the same one. As far as the 100-400 f/4.5-5.6L IS II USM lens you could have some autofocus issues with the lens. If I recall 5.6 is about the limit for autofocus to work on the lens/camera. If you double that to 9.0 to 11.2 with the doubler you may lose autofocus

If the lenses mount is EOS then yeah just get the adaptor or for whatever mount it is designed for. You may have come flange distance issues with that lens but it should work.

I am not sure. Mine only works with Canon zoom lens EF 70-300 mm 1:4 - 5.6 IS USM. It does not work with my Canon zoom lens EF 28-135 mm 1:3.5 - 5.6 IS. The folks at B&H; photo video were able to give me details.

It should. Mine came with the 2x extender, the ring to mount it to my T2i and a collar to mount it to a tripod. It is not the easiest lens to use but if you have patience you can get something out of it. I do think that there were different offers out there and this is the one that I purchasedOpteka 500-1000mm f/8 High Definition Preset Telephoto Lens for Canon EOS 1D, 5D, 6D, 7D, 10D, 20D, 30D, 40D, 50D, 60D, Rebel XT, XTi, XS, XSi, T1i, T2i, T3, T3i and T4i Digital SLR CamerasI hope that link is still valid and I hope that helps.

I bought this for my Minolta 500mm lens. I attached it to my Cannon EOS 5D MKII and it worked. You have no auto focus or ability for the camera to set the f-stop.

These extension tubes simply hold the lenses in place at a set distance from the camera. They have NO electronic or mechanical connections between the camera and the focus or aperture (f-stop) settings on the lenses. If you can manually focus your lens and manually set its aperture (using the ring on the lens), then it will work with your camera / lens combination.

It just so happens that yesterday I tried the 2.0 on my 7D Mark II with the new 100-400 II lens and it lost its AF function. It works fine with the 1.4 extender, though.

I've used this particular piece on all of my Canon EOS cameras. 1V, 20D, 30D, 1D IIn. A friend uses one on his 40D and his new 70D. Shop.canon.usa.com lists the 5D in the compatibility table (along with virtually every EOS camera ever produced, so I believe that it WILL fit the 5D III. I like this extender a lot! It keeps your cheek/nose off the back of the camera and helps to minimize grunge on the LCD Screen. You do have to be careful about snagging on the camera bag - but that's my only concern when it's on my cameras.

I use it with the canon 100-400L and it fits fine, but I have to remove the lens hood and put it on backwards. Plenty of room width-wise, even with the lens mounting ring attached.

It will work. But you will need to use manual focus. The 2x extender also doubles your f stop. So f5.6 becomes f11.2 with the doubler. Your camera will sense this and not let the autofocus work.

The Canon Extenders EF 1.4X III or II are designed to fit just some of the Canon L prime tele and zoom lenses. B&H has a complete compatibility list which unfortunately does not include your lense.

I have not used Canon EF 1.4X II telephoto extender so I'm not sure. But this lens comes with its own extender, which doubles the zooming to 1000mm, and it works pretty well, on my tripod.

The fittings will mount the fd to your cannon eos camera... however I urge you to go with a different brand. This adapter had the element too far from the sensor, resulting in a macro extension tube opposed to a lens adapter. Go with fotodiox or kodak and your lens will be ready to go. I recommend buying a different adapter for each lens if you're shooting on the go.

Always check Canon Compatibility list would be my suggestion on this! I use this on a 70-200 mm and a 400mm Canon L lens with no problem. Always make sure your battery is off before connecting it and removing it. Other than that it is fairly simple to install!

canon does have this teleconverter listed as a component that will work with the 100-400 lens

Yes it will. It will work with any Canon camera with an EOS camera mount. I use it on my 60D, but it will also work on my old Canon Elan, which is an old film SLR. I must say, I am loving this lens, very versatile.
