This is really for close up's. Love it.

So I needed some additional distance between the camera and the telescope in order to obtain focus as my telescope focuser at maximum reach wasn't able to focus correctly and the adaptor supplied with the scope was too long and took the focal length further than needed. Looked for telescope extension tube and couldn't find anything at a reasonable length (needed about 25mm).So looked at these which would achieve the same aim and also give me some macro capability.Result, added the 21mm extension tube between the scope and the camera and this moved the focus point for very distant objects into the sweet spot. I now have decent range of focuser movement when focusing on a distant object (a tree during daytime in my case) so that I can run my autofocuser and not worry about failing to achieve focus on stars/other distant objects.Tested briefly with 70D camera and 300mm lens for macro and you'll definitely benefit from using a tripod and shutter release cable when going for true macro shots as the depth of field is tiny and needs very careful positioning to achieve focus when using as a macro extension. Autofocus will hunt a lot if you aren't close to the actual focus position and this is helped hugely by fixing the position of the camera relative to the object. Hint, it's a lot closer than you might think.This might help some folks in a similar situation.

They do the job. A quick and dirty option but you really can't expect much at this price. They're really just a tube that fits onto your camera to which you can fit your lens onto. It did worry me a little as there's an uncomfortable crunchy sound doing it but I was surprised by the results compared to without them and allowed me to get much closer to the subject. It's not transformative but it's pretty good. Regardless, I can't complain at £21 (and there's a 10% voucher!)

Starting out in macro ! , don't want to spend a fortune on proper lenes until you've decided if macro is for you. Then this is for you, a cheap way of trying macro photography, you'll get decent quality images from this set of extender tubes, there decent enough made, the contacts line up, they fit together tight enough. Watch loads of you tube videos about Macro first, DONT expect your first few dozen images to be spot on, it takes time and practice, but these will do until you decide if you want to peruse macro seriously, then you'll go and buy a proper one to one lens. Good starting out point for macro, decent enough made for the price.

Very poor quality item, made of cheap brittle plastic. The pins inside will probably break off after a few uses as they are woefully fragile. Retuned for a refund...horrible thing.

Works well with all my Canon cameras. Great price and excellent delivery timescale.

Bought for Grandson who is doing GCSE photography. Took a while to work out how to do it. Has enhanced his work and at a reasonable price.

The tubes work as intended. Autofocus works as well. However, the opening/closing mechanism is rather rudimentary and of low quality. After a few days of trying, I am still unable to remove one of the tubes from my lens! Luckily it is only a Canon kit lens, but nevertheless this is rather unpleasant experience. My suggestion would be to play with the tubes by putting them on and off each other till the safety mechanism loosens up and you feel comfortable with ease of operation. Do not start by mounting these tubes on an expensive lens!
