Does it work with the Canon 1.4 Extender?

Yes...it will connect but I'm not sure about the auto focus. I belief is that the auto focus will work.

Sorry, I don't know. I use it for my telephoto lens from my first generation EOS Digital Rebel.

It should though I have not tried it. Essentially it creates a standard Canon EF mount on which you can put EF and EF-S lenses.

yes, just need to check which canon lenses you have before selecting the adapter. google it, fotodiox for instance offers them

I haven't tried it with an extender, but I don't think it's compatible. This information comes from Canon: "This converter is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L."

No. Canon extenders only work with Canon L series lenses, not regular EF lenses, which is what the Sigma is considered. I use a Vivitar Series One 2X teleconverter on my Sigma and it works amazingly well, both AF and exposure.

Neither the Canon EF Extender 1.4x or 2x will work with that lens. They work only with L primes of 135mm and longer, and the 70-200mm and 100-400mm zooms. The Extenders will not mount the 24-70mm f/2.8L, are you could damage the lens by trying. There are extenders from other companies such as Sigma and Tamron that may work with the 24-70mm f/2.8L, but you may find the image quality disappointing.

Hi Angela, I'm honestly not sure! It didn't work very well with my canon rebel T1i. It was back in the mail after a week of many attempts to use. You might be better of just buying a more reliable flash if your not sure. Hope this helps you:)

yes. I have one for my canon t4i and it works great. I definitely advise getting one.

No. It works with the following: NEEWER Timer Remote for Canon 50D, 40D, 30D, 20D, 10D, 5D,1Ds Mark III, 1D Mark III, 1D Mark II N, 1Ds Mark II,1D, 1V, EOS 3, D2000by NEEWER®

Yes and no. ALL Canon dslr's (except the 1DX) will not auto focus if the lens speed (max aperture) is faster than f5.6. The 1.4x extender will convert your 4-5.6 lens to 5.6-7.8. So, at the apertures above 5.6 you won't get reliable if any auto focus. You can use the extender if you are willing to manually focus.

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.

Yes it should. However, canon states the following in it direction page for extenders. Mounting and dismounting the Extender First attach the Extender to the lens, then attach it to the camera. To detach it, follow the same procedure in reverse. then turn the Extender counterclockwise thus removing it. This is just one way described and Kenko/Canon to perform the action. A forethought, I keep the 7D (I have)covered with the cover so the inside of the camera is not expose. It is a matter of practice. A course I leave the attach lens on until I want to change. Just take a moment to think what you want to do!! Yes it should. However, canon states the following in it direction page for extenders.

To be absolutely sure simply call Canon Tech Support and ask the question. Canon will want to know your exact lens information not simply a 70-200mm lens. Obviously I own this extender and other photographers have tried to use this extender with their lenses, in this case both the the lenses were "L" series Canon lenses and in one case the extender would not couple with the lens and in the other case the extender did couple to both the camera and lens but the autofocus feature did not work. Canon has the answer for you, call 1-800-652-2666

No it won't, it will only work with the EOS-1D or EOS-1D X This lens is only compatible with fixed focal length L-series lenses 135mm and over, as well as the EF 70-200/2.8L, EF 70-200/2.8L IS, EF 70-200/4L, and EF 100-400/4.5-5.6L. Additionally, please see the lens and/or camera body manual for full compatibility information with the Extender EF 2X II.Back to Top

The extender will not work on a 24-105, generally it only works on lenses that go past 135mm (with some exceptions see http://en.wikipedia.org/wiki/Canon_Extender_EF for a list of compatible lenses).If you put it on a lens with max aperture of F/4 it will change it to f/5.6.

Linda I have this extender but my camera is a canon 5d Mark II so I don't know. You might call B & H photo they will tell you and you wouldn't have to buy from them. Nancy FordWHNPA www.nancyfordphotography.com
