The perfect close-up tool
Well made tool. Precisely couples with lens and camera body. Smooth mount/dismount. Excellent functionality within the range for which it is designed. It really makes a difference when deciding between original Canon products and cheaper second market items. Stick with Canon when it comes to lenses and accessories like this one.

I bought this for my wife without really understanding what it does. This is for EXTREME closeup photos. Having seen what it is and what it does, I wish I had bought either a generic extension, or a different piece of equipment all together. The quality and performance are great...but it was [$].

I bought this short extension tube along with the 25 mm extension tube for use with my 100 mm macro lens for close up and macrophotography. Although there are other extension tubes in the market, I preferred this made by Canon, because I know it to be a precision device designed to be a perfect match to my Canon equipment. I have used it, and it has performed exactly as I expected.
Does a great job of getting you in close for macro focusing. No additional optics to mess with your image, just an air gap behind your lens. Can be used with most every EF lens so it's a lot more versotile than a single macro lens costing HUNDREDS! You'll like it.
Great for inexpensively adding macro capability to pretty much any EF lens. There are no additional lenses in the unit to affect your image, just creates an air gap between your lens and the body. Simple as it gets.
I use this tube with my EF 100mm L series macro lens for... you guessed it - macro photography! Works exactly as expected. Build quality is of the typical high quality that comes with the Canon name (hence why I chose it vs. Kenko).
Canon quality, passes the electronic controls through to the lens. I am happy. Yes, I would love a 100mm USM Macro, but for the time being this works well enough for my tasks (which is photography of small electronic components).
not an exciting item, but adds macro function to several lenses
I guess I didn't realize that the Auto-Focus would not work with this extension tube. It only means that you have to move the camera to focus. Since things are very close by definition that isn't a serious problem, only a surprise.
Weight, someone asked: Weight: 2.3oz / 65g
This extension tube works with all my lenses & allows me to get from a few inches to a few centimeters away from details I really want to isolate & highlight. Best buy I've made all year.
