Cactus with Water Drop

Handheld, macro extension tube.

A belated birthday present from Devra. Thanks! The little chicken stuck in the pot was also cute but not quite as photogenic for a macro shot.  Somewhat splintery.

Extension Tubes, the Poor Man’s Macro Lens

A few weeks ago, while browsing photos in the Canon 50mm f/1.8 lens pool on Flickr, I saw a macro shot of a fly’s eye. Since I can’t get closer than 16 inches to an object, I asked the photographer how he did it and he told me about extension tubes. I found a cheap set on AmazonUK. For £6 for a set of three tubes, what could I lose? These are extremely basic extension tubes, basically a tube of plastic with couplings for the camera body and lens. You have to focus manually.

In the reviews someone posted a method for setting the aperture with these tubes: you set the aperture with your lens on the camera. When you press the button to release the lens, keep your finger on the button, and then insert the extension tube. I haven’t tried this but in theory it will retain your aperture setting.

These tubes do have a locking mechanism. There is no documentation, so make sure that you know how to release the tube from your lens. The Canon 50mm f/1.8 lens is not very robust, to put it gently, and it could crack or fall apart if you try to force a tube off the mounting. A small silver button slides up to release the tube from the lens, but it’s not obvious.

The Kenko extension tubes, available on Amazon.com, are more expensive ($169) but you get the autofocus (and, I presume, aperture control as well). It still costs a lot less than a macro lens, however.

Finally, if you’re on a really tight budget, here are instructions for a macro tube made with a Pringles can! I wouldn’t have the courage to try this with one of my lenses.
