Enter a hidden world with Phottix 3-Ring Auto-Focus Extension Tubes

A whole photographic world lays hidden from sight. Broaden your photographic horizons with Phottix Macro AF Extension Tubes for Nikon and Canon Digital SLR cameras. Shoot macro images without macro lenses.

Unlike traditional extension tubes the new Phottix AF tubes feature electronic connections for lens autofocus and aperture functions.

Macro extension tubes are an inexpensive way to experiment with macro photography. Flowers, insects – anything you can think of – can be photographed in minute detail. There’s no need to spend several hundred dollars to photograph the hidden world.

How do Macro extension tubes work?

Extension tubes do two things: They shorten the focal distance of a lens, and they magnify what is being photographed. Why? Because the tubes move the lens further away from the camera’s sensor. One drawback – with the lens further from the sensor you will require more light for a proper exposure. A tripod and a wired or wireless remote are a must.

What do the different sizes of tubes do?

Extension tubes are sized in millimeters. Use the following formula to calculate the magnification from specific extension tube sizes:

Magnification = Extension Tube Length / Lens Focal Length

Example: using a 31mm extension tube between a 50mm lens and a camera body would result in magnification of 0.62x (31 mm / 50 mm).

The Phottix 3-Ring set come complete with 13 mm, 21mm, and 31 mm tubes, These can be combined to get super-close to your subjects.

Using all three with a 50 mm lens would give you a magnification factor of 1.28x (64 mm / 50 mm). That’s close. Past 1x and you find yourself in a strange, almost alien, world of details.
