Teleconvertors?

Discussion in 'Other Cool Gear, Camera Bags, Camera Straps' started by Argent, May 21, 2007.

  1. I'm trying to do some research on these and was looking for some people with firsthand experience with them. My limited understanding thinks that if I put a 2x Teleconvertor on my 70-300 it will effectively make it a 140-600?

    Also - while they appear cheaper than buying an actual lens that size - are there other inexpensive options to the Nikon 2X which appears to be $400+ (sigma, tamron etc)

    Guess I'm just trying to gather up whatever information I can so I can make an informed choice about getting one (or not) or if it's even in my camera budget.

    Thanks

    From my experience from a purchase at Adorama of a pre-owned Nikon TC-20E for $192.00.

    Used for my D2x/70-200mm VR combo. Effectively turns a 70-200mm into a 140-400mm which when place onto a D2x (with a 1.5 multiplier sensor) becomes a 210-600mm in normal mode and a 280-800mm in HSC mode.
    Of course the minimum f/2.8 turns into a f/5.6 with the teleconverter attached so it will affect your AF and the photos won't be as sharp.

    Just noticed that you have the Nikkor 70-300G ... the TC-20E nor TC-20E II will not attach to that lens.

  4. You cannot just look at the magnification. Most important is the speed which it effects. You mention the 70-300, which is f5.6 at the top end. If you put a 2x on it that would f11, which is really too slow to make it purposeful. The TC's are really made for longer primes and a VERY few faster zooms. The 300 f4 and 300 2.8 and above and mostly like the 70-200 and 80-200 2.8's. The Sigma 100-300 f4 apparenetly accepts them quite well.

    Hope this helps
