  • Kenko 2X Teleplus PRO 300 DG AF

    7 out of 10 points and recommended
    2X, works on most lenses, higher than expected image quality, price
    none

    I got this and the 1.4x in an attempt to extend my range on my 70-200 and expected worst because I had tried the Canon version and was disappointed. I didnt want to spend that amount on something I would be disappointed with so I opted for something cheaper. I did a fair bit of research looking at photogallery sites at samples and reviews. When I got it.. and took my first shots.. the images were better than expected. On my 70-200 IS, 5.6 was soft but this was expected. This thing magnifies the flaws of the lens 2X. However, when I stopped down two stops.. the images were pretty sharp. Bokeh wasnt was great as without but this was again expected. I reduced the stop from two to one and still found the images sharp. Moving down.. the minimum closing down that produced sharp images started at f7.1 and got better up to f11. This coincides with the MTF of this lens where the highest resolving value lies between f3.5-5.6.

  • Kenko 1.4X Teleplus PRO 300 DGX AF

    9 out of 10 points and recommended
    Clean, sharp, cheap, fits most lenses
    none

    This complements my Kenko 300DG pro 2X well giving me a 98-280 and 140-400. Needs to be stopped down 2/3 stops for optimal resolving power.
