The Canon EF 25mm Extension Tube II is used to allow a lens to focus closer than it would normally. This is accomplished by moving the lens 25mm farther away from the camera body's film plane or digital sensor by fitting between the camera body and the lens. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits and when using the camera's TTL metering system, no exposure compensation will be required. This updated version II is now also fully compatible with Canon Digital EF-S mount, as well as standard photo EF and TS-E fittings. Extension Tube EF 25 II is recommended for focal lengths of 50mm and up (EF-S 18-55mm can be used at middle and tele zoom settings). More
Canon produces tubes in two different lengths - 12mm and 25mm. The EF12 and EF25 tubes come with electrical contacts which allow data transfer between the lens and camera to be maintained. It is possible to attach the EF12 tube to the EF25 tube to give a 37mm extension. Canon does not recommend this, as the data transfer may be affected, but acceptable results are possible if you are willing to experiment.

About Me Semi-Professional
Comments about Canon EF25 II Extension Tube:
The Canon 25mm Extension Tube allows you to turn a fast Standard Lens into a fast Macro lens, something that is not generally available.I use this product to take closeup shots in very poor light.The tube is structurally robust, which is essential in this application.THe drawback is that the focussing range, (or the magnification range) is extremely limited, so you need to know exactly what your subject will be before you set out.
Bottom Line Yes, I would recommend this to a friend

Macro photography at an affordable price
By Bryn H
About Me Hobbyist/Enthusiast
This device allowed me an inroad into macro photography without the expense of purchasing a dedicated macro lens. Although expensive in comparison with some third party offerings it has the usual solid Canon construction and works faultlessly with my 70-200mm lens. Fiddlier to mount and demount but no more so than an extender. This is a new area for me and I am still experimenting with best practise but I have obtained some very pleasing results so far. I still feel it is expensive for an empty tube.

Great for use in conjunction with a 50mm prime or zoom. This will take you into a whole new world without having to invest heavily.

No mean feat
The extender is helpful, simple to use and increased the capacity of your selection of lenses in taking macro pictures.

More sense than a macro lens
If you can't justify spending hundreds on a macro lens, this extension tube allows any Canon lens to produce extraordinary close-ups of tiny objects with no loss of quality. And if you get other lenses in the future, you can still use the extension tube with those too. Yes, it is overpriced (like every other Canon SLR product or accessory) but in my opinion is a much better idea than spending hundreds on a dedicated macro lens that you might rarely use. Versatile, light, much more sensible than a 3-tube kit, and full Canon quality.

Close-up capability for almost no extra weight
I bought this to use when travelling light with my 70-200 F4 and negate the need for a dedicated macro lens. It works a treat, at 70mm working distance is very close (too close probably :-)) and by 200mm it is about a half meter.Quality is excellent and while it doesn't give true 1:1 macro capabilities, it is very nice for bugs, butterflies etc.My only gripe was the price is a bit steep for a bit of air!
