    Would it be possible to stack two 1.4 TCIIE's? Anybody tried it or know that it will or won't work? 2.8 result?

    I've heard you can't do a 1.4 and 1.7 together, but can do a 1.4 and a 2.0 in theory. (may require some mod?) But not sure about 2 1.4's.

    Not saying the image quality would be decent, that's a whole nuther subject. But if you did it, what quality did you get? (if it can be done)

    thanks.

    I don't know if it's possible, but if it is, it'd be 2x (1.4 x 1.4 = 2).

    oh, ok, so you'd multiply them instead of adding them. So, a 1.96 hmmm....

    But 2.0s don't have to good a reputation, so not sure how this would compare, if it is possible.

    Doug,
    I have both the TC14e and TC17e. They both have extended glas in the front and will not mate even close with another converter. It may be possible with non-Nikon converters but not with the Nikons.

    I think the 2.0 would be better than the two 1.4s. Must be less glass involved and therefore probably less distortion from all the correction going on inside.
     
  6. Doug,

    The following article spells out what is and isn't possible with respect to stacking tc's. http://nikonpages.heymanphotography.com/tcmod/
