Auto Focus Macro Extension Tube for Nikon - $275

Auto Focus Macro Extension Tube for Nikon AI Camera

These extension tubes are very solidly built and are high quality metal tubes, unlike cheaper units around. Have tested the identical Canon eos version of these myself on my Canon 5dII and they work so well I have purchased a set for my own use!

This is used by attaching between camera body and lens of the 35mm single-lens reflex camera. It comes as a set of tube of different lengths which singly or in combination makes it usable in 7 different lengths.

It couples perfectly with the camera's automatic diaphragm.With cameras of TTL,AE(Through-the-lens,Atuomatic­ Exposure) type it gives perfect coupling except when combined with electronic flash AE unit.

It's dim ensions are:

Tube diameter : ab.62mm.

Tube Lengths: (1) 13mm.(2) 21mm.(3)31mm.
