Extension Tubes? - The Photo Forum - Photography Discussion Forum
The tube contains no optical elements; its sole purpose is to move the lens farther from the image plane. The farther away the lens is, the closer the focus, the greater the magnification, and also the greater the loss of light (requiring a longer exposure time). Lenses classically focus closer than infinity by moving all optical elements farther from the film or sensor; an extension tube simply imposes this movement. Below is a web page for a 25mm extension tube in the Olympus 4/3 mount. This page shows an the official, 9-contact, autofocus capable, top-grade Olympus brand extension tube. If I had only one,single tube, it would probably be a 25mm extension for close-up, high-magnification uses with a 100 to 135mm lens where I wanted the biggest subject magnification on small things like bugs. This extension tube has full contacts, and will maintain all camera functions with the tube installed with AF 4/3 mount lenses on your Olympus camera. Typical lengths are 12, 25, and 36mm, and some of the sets are sold in three-ring sets. Kenko makes the 2nd best full-contact, full function autofocusing extension tubes, which can be bought in sets of 3 from B&H and Adorama and other top retailers. Pro-Optik and Opteka make third-level tubes, which sell for less than the Kenko brand, but still have full contacts and maintain all camera functions. Then there are REALLY CHEAP Chinese-made tubes that have NO electronic contacts whatsoever, and which sell for under $15 on eBay...I cannot recommend those unless you have older Nikon mount or M42 thread mount lenses which have manual diaphragm control; on new cameras and newer lenses, the el-cheapos are a PITA.
