Teleconvertors & Lenses


I recently bought Nikon 70-200mm 2.8 ED lens and also a Kenko 1.4x teleconvertor they both where used but work great, can the teleconvertor (also the 2.0x version) be used with other nikon lenses or lenses made by others (sigma, tokina, tamron, etc.)I know that Nikon says that nikon teleconvertors only work with special (high end lenses). Also when I say work also meaning mount up & auto focus

  hey charles,
i'll tell you what I know with the equipment I have.i have minolta film cameras.my 1.4 will work with auto,not a great loss in f stops but my 2x I lose auto focus.as far as the mount goes,only as far as I know if it has your mount you are good to go.some of the newer lenses for digital may not work.i have a manual focus lens that won't work because it doesn't communicate with my camera.if the other brands are of the same bayonet mount I think you'll be ok.
hth,sam

Charles E. Mann   thanks Samuel. I to have a manual Minolta with a teleconvertor (2x) I understand the loss of F stop. The are a lifesaver. I was concerned about the off brand teleconvertor & other lenses other than the Highend (expensive glass). Can they be used with a Nikon G lens or any other non pro lens.

  boy charles,thats out of my league.i know very little about other brands.
try a search here.might help.
sorry charles I don't have a clue.
give it a go on nikons website on compatibility.
i don't have higher end anything.i buy used anymore because people buy new and lose interest.
don't even know what camera you have?
i would never have purchased a kenko myself but hey.
i'd say your at a point where you need to do some research on what you have,and purchase nothing else until you do.
i love MY equipment and it's abilities.i check out many offers,but try to settle on my limitations.
there is a nikonian website.
ah do a search,help you a lot more than I can.
i find it hard to believe there isn't a nikon owner out there who hasen't wanted to help you?but not really surprising.
maybe the me thing has overtaken the we thing?
but if you need help in settings give me a ring.
hth,sam

Charles E. Mann   Thanks again samual. There's a vendor show at one of the Camera shop here coming soon I think i'll try to get get my Questions answered there. Like I said I buy used also. I think that I have bought about 90% of my equipment used & havn't had a problem yet. Some hard to find used items I will buy new in the near future. Good shooting

Bob Fately   CHarles, I have the 70-200 and Kenko TC (also the 3X TC) and they work fine. I also use the 1.4 TC on other lenses - the Sigma 180 macro, the Nikkor 24-120 AFS VR, the SIgma 120-300 f2.8 and the Nikkor 85MM f1.4.

In general, TCs can be problematic with lenses that have protruding rear lens elements - but none of the lenses I mentioned (nor most telephoto lenses) have this king of design.

The Kenko pro level TCs are almost as good as the far more costly Nikkors. The reason Nikon indicates that a TC is "made" for a particular lens is that they optimize its design for that telephoto - every lens has some optical issues and by pairing off a specifically designed TC you just get better results.

Other than the rear element thing, the Kenkos will work with any lens that works on the camera itself. Auto-focus, VR, etc., are no problem.

So go forth and take pictures - I hope this helps. SOrry I didn't respond sooner - I sort of took the weekend off...
