What telephoto extender will work best with this lens?
744851
I have tested the Canon 1.4x teleconverter and it works well. AF is also listed as possible even for the Canon 2x teleconverter. Listed here: http://www.bhphotovideo.com/FrameWork/charts/canon1_4xExtender.html http://www.bhphotovideo.com/FrameWork/charts/canon2xExtender.html Here is the list for the Kenko Pro 300 teleconverter which is a highly rated teleconverter and it is compatible with the the lens as well for both the 1.4 and 2.0: http://www.kenkoglobal.com/pdf/TELEPLUS_DGX_series_CompatibilityList.pdf. Obviously, things will be more challenging with a 2.0 teleconverter but not impossible. It will all depend on how steady you are with the camera(tripod), you ability to focus manually, and the amount of available light etc.

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.

I have the same lens & teleconverter and it works perfectly. Good luck hope you enjoy this setup. Wayne

Daniel, It's been a while since your post, so you may not need to this info anymore, but I'll pass it on anyway. I would suggest reading the link below for all kinds of info relating to Extenders and Extension Tubes. The answer to your question, which is also on the following link, states: "Most extenders are designed to retain the focusing range of the original lens". http://www.bobatkins.com/photography/eosfaq/closeup2.htm

You can always buy some automatic extension tubes. I use them all the time with my Olympus lenses. Neewer, Fotasy, and Fotodiox makes them.

The bundle I purchased did not have a telephoto, but it did have a wide angle/macro lens and there is an additional adapter ring 9labeled 49-58mm0 that needs to be placed on the bottom of the lens before attaching it to the mounted 18-55mm lens that came with the camera. It is the same with the telephoto lens adapter that came in my package. By the appearance of your package in the email, I believe that you received these adapter rings.best wishes

Not sure with what Nikon lenses it would work since what I have is for a Pentax body and I can't use it with any of my AF or manual lenses except with my 1000mm & 2000mm mirror manual lenses due to the extenders element protrusion into the back of the lens cavity. The Sigma design is similar to those extenders of Canon. For my Nikon D7100 I use a Kenko DGX 2x extender which works perfectly well and it delivers good sharpness. The Sigma 1.4x for my Pentax does deliver good sharpness with my mirror lenses which I use to video distant birds.

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.

No this is to increase the zoom for macro photography. It does not work with a telephoto lens, the camera will not be able to focus. You would need to look into getting a telephoto extender

Hi Cynthia, The extender won't help you. It's for DSLR cameras. What you need is a Celestron 93626 universal adapter. If you wish to see how these work, look up "Digi-scoping" on YouTube. Hope this helps.

I use it with a Panasonic FZ200 Bridge Camera. With larger telephoto lenses I would look for something more robust.

I dont have the same body and lens you have, but I can report success with a 70D body using a Canon 70-200mm f/2.8 using this extender. The fstop jumps to f/5.6 and the autofocus still worked perfectly through the next 2 or 3 stops.

I bought both the Vivitar wide angle and the telephoto. I use them with my PadCaster to change the focal length of the iPad. I have been satisfied with both lenses, especially given the price. I have suggested to PadCaster that they design a turret so I can mount both lenses and easily switch between them. No response from them. (They are not Carl Zeiss, Canon, or Nikon quality, but they work for me.)

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?

I would go to the Nikon web site... look at the teleconverter section and find this model and then go to the compatibility section for lenses it is compatible with ...... I would be leary about purchasing them (especially used).........

While Doug James answered this correctly, I did look up this lens on Canon Lenses. Normally, this is an f4 to 5.6 lens and is an EFS lens for C size cameras. For extenders the widest f-stop that is acceptable is f 5.6. So when you are at f 4.0 you might be able to use this but it would be very limited. You might want to try Canon extension tubes for magnification. The 25mm seems to do best with this lens. Remember though that infinity focusing is generally lost with extension tubes.
