Digital SLR Cameras Top10 |

I have Nikon AF-S DX NIKKOR 18-105MM F/3.5-5.6G ED VR

Nikon AF-S 35mm F1.8G DX Lens

Sigma 70-200mm F2.8 EX DG Macro HSM II Lens

I have these 3 lenses, now i am planning to buy an extension tube

i.e. KENKO Automatic Extension Tube Set DG AF Macro – Nikon

will this tube will be allright for my DSLR?

thanking you

While the Kenko rings do have electrical contacts that do give you autofocus, extension rings to reduce the amount of light that gets to the sensor. Beyond a certain point you will lose autofocus because you don’t have enough light for the AF system to work. A lot of cameras don’t autofocus if you have less light than the equivalent of f5.6 reaching the AF sensor.

So yeah, the kenko rings will AF, but you’ll probably want to use it with your Sigma and the 35.
