Hi. I am not sure about that lens. Sorry I can't help you. Did you check the canon USA web site under lenses to see if the info might be there?

Yes, it does fit the EFS 18-55mm lens. However, the effective macro isn't astonishing.

The EF-S 18-55 mm IS lens and the 55-250mm IS lens are made by Canon, not the case for the Telephoto and wide-angle lenses.

This is an A mount lens, you will need an adaptor for it to fit the E mount.

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, this one is for Canon FD lenses (old ones 70's I think). You need one for EF lenses.

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.

Taking a nature trip in a couple months to national park. I have a Canon 50D. Thinking of getting a Canon EF 100-400mm f4.5-5.6L IS USM Telephoto Zoom Lens and Canon EF 1.4X II Extender. With these lenses work with the 50D? What about AF and IS?

It appears the EF75-300mm lens and the 18-55mm lens both have a 58mm filter size, so you would need the Canon 250D 58mm close-up lens, not the 77mm version. Canon does make this 58mm close-up lens for this purpose (though listed as out-of-stock on Canon's web site, I have seen it listed on eBay and Amazon). With the zoom lenses, you will find that certain zoom setting will not work well or at all, but you just need to confine yourself to the working range and move the camera into the correct focusing position. Verify your filter ring size first, then go find the correct diameter version. Have fun!

The lens must be a Canon EOS EF mount. Remember, no lens auto (auto focus/aperture) functions. Also, the 4/3 sensor will crop the image making your lens longer.

It will not work with your kit lens. There are no teleconverters which will fit EF-S lenses.

Yes, the lens will fit on and work with any Canon DSLR model with an EF or EF-S lens mount.

I know that you have to buy a ring adapter to fit in between.without it, it won't mount. It depends on the lense. Look for a ring adapter that is compatible with your EF50. Good luck.

Hi Chloe, I just tried the reversing ring on my 18-55 efs lense and it worked. Try to take the large part of the ring and carefully screw it on the front of the lens. then fit the small end on the camera body. Please let me know if that works or not. I hope I have been of some help to you

Probably not. The extensions are designed for macro photography. It seems like the 55mm would allow you to be close enough. I just tried using the mounting rings with my 55-250 lens. Not being sure what you are trying to do, I would suggest trying it. You may want to use the extension rings anyway. But you may want to consider a smaller lens with the IS and autofocus capabilities.
