Kenko TC - 2 models - which one to buy?

(1/3) > >>

xps:

As read in the lens rumor forum, with an kenko TC the AF is working on an 100-400L. But which Kenko to buy?


Kenko 1,4x Teleplus Pro 300 or the MC4 AF 1.4 DGX?

What ist the difference in between them?

The reports of f/8 AF that I've seen have been with the Teleplus Pro 300 DGX.

Mt Spokane Photography:
Only the 1.4X is going to AF with the 100-400L.  A 2X would give you f/11 at 400mm and will not AF.
If you have a f/4 lens, a 2X will allow AF.
I'd also be concerned about more distortion with the 2X.

Get the new dgx, it reports exif data better/cleverer so it does af @f8. But really the newest one (there seems to have been a silent update by Kenko, so there are two ean codes for the dgx). Forget 2x, the iq will be too bad with your zoom, not to speak of af speed.

ean codes are Amazon assigned numbers, each seller can assign his own.  They mean nothing
