can you use this converter with canon EF 70-200 f/4 lens

Really not sure, but it works with alley other EF lenses. Note: use in manual mode only, does not pass through electronics.

Yes, it may be used with that lens...effectively turning it into a 140-400 f/8 lens.That effective aperture is important because only a handful of bodies will allow AF with an f/8 lens. (1D series and possibly the 5DIII)

Yes, Sure. I use it and it is turned into 140-400 Lens. But you lose one stop but please note that you will need to use a tripod.

The answer is yes as long as the converter comes with the camera. I returned this lens because the converter was missing and there was no way to attach it. Read the entries carefully prior to making a purchase.

Being EF lens I think it should work but I have to verify. My other L-series lenses (24-70mm f2.8 and 70-200mm f4.0) worked with my old camera, D20.

It should work with all Canon super telephoto lenses. Canon's website or the lenses manual will confirm this information. It works with my 70-200 f2.8.

Not the 1.4 converter, but with extension tubes. You can retain auto focus with the right extension tubes. Kenko DG Auto Extension Tube Set for the Canon EOS AF Mount works for me.

You must have the 16mm F2.8 in addition to this converter. It an accessory to the SEL16F28 Interchangeable Alpha E-Moune lens. There's also a fish-eye conversion lens available VCL-ECF1

You need EF mount lenses. EF-S mount lenses will not fit this teleconverter. In general, teleconverters are a bad idea unless you use them with very high quality lenses. The converter will magnify any flaws the lens already has. It would be more cost effective to buy a longer prime lens than trying to use a teleconverter on any lens with a maximium focal length less than 100mm. You would also be better off just cropping your shots from a telephoto lens that has a maximum aperture narrower than f/2.8 or f/4. Since any 2X converter doubles the effective focal length, it also increases the maximum aperture by two stops. An f/4 lens becomes an f/8 lens. An f/5.6 lens becomes an f/11 lens and so on. An inexpensive telephoto lens such as a 70-300mm f/4-5.6 becomes an effective 140-600 f/8-11. Most Canon bodies disable auto focus any time a lens or lens/converter combo with maximum aperture narrower then f/5.6 is mounted. The 1D series wil allow auto focus to function up to f/8.

I don't see why the 70-200 would not work...it's very adjustable. I don't do too much follow focus with it, it's ok, but not the best for that, but none of these type of focus design work all that well for me.

Yes it can be used. I bought the 70-200 lens to be used with my Rebel Xsi and it worked well. I have since upgraded to a 7D. The 70-200 is the best piece of glass I own and makes every camera better!

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

It should work. The Tokina is a 2.8 lens (good), and the t4i is a standard canon. You might notice these teleconverters are not recommended for less than a 100mm lens (and your lens is obviously right at 100mm). I believe this is due to edge sharpness, as the narrower the field of view does not use all the glass. However, you might have noticed that these don't work with any of the EF-S canon lenses, and the lens from those stick back farther. Not seen what the back of the Tokina looks like, so that issue is one you should check.

Very sorry I can not answer your question because I do not know what kind of mount Fs700 uses. This adapter allows Canon M camera use all EF lenses and all EFS lenses. If your FS700 has the same mount as the Canon M camera, physically it can mount any EF and EFS lenses but I am really not familiar with FS700.

It won't work well, you need a full manual lens with aperture ring to use it in this adapter (in any adapter I think) otherwhise you won't be able to control the aperture and it will stay at F/22.You need something like this: http://www.amazon.co.uk/dp/B0000BVDZC

I have not used with 70-200 f/2.8L IS, but I've used it with 24-70 f/2.8L and it's fine. I guess you'd attach the fastenr to wherever you would normally mount the camera on a tripod--and in the case of 70-200 f/2.8L IS, you would mount that camera on a tripod using the tripod ring on the lens--so I think you're doing it correctly =)

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!

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.

You will likely need an adapter. I had to have one to allow me to fit it on my 24-70 lens which takes a 77mm filter.
