I bought a macro lens a while ago and like taking macro photos but heard that with extension tubes you can get much closer. I have a Canon EOS 400D and think my macro lens is the Canon EF-S 60mm f/2.8 USM Macro Lens. I was looking on ebay and found quite a lot of extension tubes, but some cost about £3-5 and others are £80+. I'm not really looking to spend much money so wanted to know if anyone knows if it would be worth getting one of the cheaper ones and if they work well and would do the same thing, or if they are just cheap knock-offs that dont work.

One of the ones I saw was

They should work fine as the "high-quality" air inside them are all the same...
That said there's are two kinds:
1. The straight tube which your link is do not transfer the aperture - i.e. strictly manual control
2. The 'auto' kind which has the pins for the electrical contact between the camera and the lens:

-> Given that most macro shots are taken in manual anyway I would only pay extra for the 'auto' ones just for convenience all depending on your budget...

Ok, thanks for the response. Think I might try and get one then since they aren't so expensive.

On 2nd thought you should go for the 'Auto' one as unlike the FD lens the EF-S doesn't let you control the aperture on the lens

Ok. Think I'd rather do that then. Will just have to wait a bit longer till I have some spare money.

All third party extention tubes are made by Kenko, regardless of the brand engraved on the barrel. Kenko makes two kinds. The first uses the same barrel and locking latch that they use on their teleconverters. They have a molded (usually blue) plasticlatch. These are good quality. The second set uses a chrome plated metal latch. These are made to lesser tolerances, don't fit well, and some have even complained of light leaks.
