Re: Teleconverter magnification comparison. (5 imgs)

Thank's Ron.

I just measured the scale increase on your photos:

Tamron: 1.386

Kenko: 1.382

Promaster: 1.532

Pentax: 1.748

(measured on screen with a tape; precision is less then the 3 digits show; should be about 2 digits; the difference between the Tamron and Kenko is not significant).

It is strange: just tested again: my Kenko "Pz-Af TELEPLUS 1.5x SHQ" gives me 1.57x (measured with the Pentax F 100/2.8 macro, at more then 500m of distance). It seems that there has been more then one version of this TC.

Cheers - Klaus
