AF Auto Focus Macro Extension Tube Set for Canon EOS EF EF-S Lens DSLR Cameras 1100D 700D 650D 600D 550D 500D 450D 400D 350D 300D 100D 70D Close-up(13mm 21mm 31mm)

If you shoot macro photos his is an accessory that you will want in your bag. I use Canon 60mm and 100mm macro lenses. The addition of an extension tube will improve your macro ability. I test all the tubes with both of my macro lens and all passed lens info to the camera. For the occasional shooter these will serve your needs. One of the tubes is a bit tight but other than that I have found no problems. For the money I rate this kit a 5.

These are seriously dirt cheap AF extension tubes. They can be fiddly to get the contacts to communicate correctly, and they're rough turning into place. I don't know yet whether the latter problem will eventually work itself out and perhaps fix the former as well. I would NOT use these in a professional environment like weddings because I think the screwing around to get them to contact properly would not be copacetic with that environment. When the contacts aren't working you don't just not have AF but the camera error 99s until you get them on just right. It's a cheap way to get started or just play around as a hobby though. Once they're on they don't seem to lose the connection, it's just that initial installation that's irritating. They also don't really feel durable enough to withstand jostling around on a shoulder strap. I remember bumping into a lot of chairs back in the day. I feel like they'd snap off.

I’ve never had plastic tubes before, but they worked just fine on a 6d and 5d Mk ii. I gave these five stars because the value for money. At the time $22.

I decided to try these extension tubes despite the ratings here on Amazon. For $20, it wasn't an expensive gamble. I'm breaking up the review into sections. These were used on a Canon EOS 250D 1) Build Quality: in a word, pure plastic. Those seemingly metal mount rings in the picture are just plastic coated with a faux chrome. 2) Error messages: When mounted to the camera, they would throw error messages, which required me to restart the camera each time. The connection isn't lined up correctly, and I had to "fiddle" with the extension tube in order to avoid the error message. In either case, no auto focus. I managed to get a couple decent shots, but it was too much of a hassle dealing with reseating them and restarting the camera. 3) Mount: I don't trust the release buttons as they seem like they could break at any time, and the tube gets stuck in the camera. They are flimsy, and fit rather tight on the lens mount. As the mount ring is plastic (faux chrome), it'll either wear in (with plastic debris finding its way into the camera body) or it'll break (with plastic pieces in the camera body). Add to that the connection pins don't align. I could forgive the cheap build quality if they functioned as advertised, but they don't.

So I needed a cheep macro tube for a photogrametry project and this was the cheapest option. It's all plastic and feels like a toy one might get at a discount store. It works for what I need and the autofocus functions - but it just feels so cheep, like one day it's going to break and not come off the lens or body. The important part, the pogo pins, that link the AF motors on the lens and body are of good quality I think so if you need something in a pinch these will do. otherwise buy something else that has a metal body.

I SO LOVED it, is an amazing quality, perfectly described for my camera and specific so im super happy, 10000% recommend ❤️ for sure 😍😍 thank a lot🥰

May not be the strongest but it works great.

They are fine. I had to do some work to make them fit and they are still pretty tight. I've used them a couple of times with pretty good results. I got these specifically to play around with and decide if I wanted to buy the nicer set, and they worked great for that process. I have not yet thrown a lens at it that didn't work. They don't feel super sturdy and you are probably going to have some concerns about them releasing from the lens.
