Kenko SLR Teleconverters

Hello all!

I found these ones in BH but I don´t know which one is better and why to use UW. Would I get a 2:1 using them with a macro 1:1 lens ?

Kenko 2x AF Teleplus DG MC4 Autofocus Teleconverter for Nikon AF $ 94.95

Kenko 2X MC7 DG Teleplus Autofocus Teleconverter for Nikon AF $ 134.95

Kenko 2X Pro 300 Autofocus Teleconverter for Nikon AF-I & AF-D $ 199.00

Kenko 2x Teleplus Pro 300 DG Autofocus Teleconverter for Nikon AF-D $ 214.95

Thank you!!

Teleconverters are used to increase the focal distance of lenses, at the expense of a certain amount of light. The first 2 you list are older versions. I would guess the last 2 are actually the same thing, which is the latest version of this TC. It works fine with Nikkor lenses that have a maximum aperture of F4 or larger.

This TC will give you 2:1 in combination with a 1:1 when shooting at the same distance, or can give you say 1:1 at a greater working distance.
