    Hi all,

    I'm looking at extending a 70-200 VR on a D2X to get up to approx. a 500mm capability

    Which type is best ?

    (also: where is the search feature on this site ? )
  2. Using the nikon tc 1.4IIe and high speed crop feature on your camera will yield 560mm with extremely clear results and a net max apeture of f4. Pretty darn good!!

    Search button is at the top of the page (magnifying glass icon).
  4. I have the 1.4 and 1.7. Both are fine. You might want to visit Ron Reznick's site. As I recall he grades them in the following manner (on a scale of 1 best to 10 worst):

    1.4 -1
    1.7 -2
    2.0 -10

  5. While I generally agree completely with what Ron says, I must be a very lucky person with an exceptionally good copy of a TC-20E. I do agree in general, but I don't find the difference to be that dramatic. I have seen at least 2 copies where this is the case, specifically when used on the 70-200. To be completely fair, those were on D100, D1H and D2H cameras, not the D2X

    I do agree that I would most certainly use the 1.4 or the 1.7 before the 2.0, just to preserve the best AF performance.
  6. I had the 2.0 as well. I bought it because of the classic "man" syndrome: if some is good, more must be better. I used the 2.0 a lot wit my D100; I found the images with the 2.0 and the 70-200VR a bit hazy, but, as you suggest not horrible.

    Some people tend to forget that you should treat a lens with a 2.0X teleconveter as a lens that really is 2X the focal length since everything is magnified. Throw in the other 1.5X crop factor and you got yourself the requirement for a verrrrry good tripod and/or mirror lock up, good stable platform with some absorbtion, and very high shutter speeds. I get a feeling a some people might be faltering in that area when testing the 2.0X TC.

    That said, the 2.0X TC tends to work far better on sharper lens... like the 200mm f/2. Alas, that's some crazy money we are talking about.
  8. Rich and Carroll, both EXCELLENT points.

    Carroll, you bring up one that is so often overlooked, even without TC's. Just using the "standard" 1/focal length to determine minimum shutter speed we often forget the 1.5 factor. Through in a TC and it gets worse. Do crazy things as I sometimes do, stack a TC-14E and a TC-20E and the numbers get crazy rather quickly.

    Couple this with the other thread regarding "sharpness" and it gives a lot of room for thought.
