Andoer Metal TTL AF Macro Extension Tube Ring Auto Focus Colorful Compatible with Canon EOS EF EF-S 60D 7D 5D II 550D

These work quite well, I tried the 21mm tube with a Nifty Fifty on my Canon and tried to duplicate slides and negatives just for fun and a 35mm slide is full frame and the auto focus and exposure worked great. I only have one complaint, when I just got them the 13mm tube did not want to separate from the 21, not wanting to combine them at the moment I struggled with them for several minutes, eventually they did separate but the little pin on the 13mm tube does not want to lock now. The lens can securely mount to it but it does not lock in place so I will have to be careful not to twist the lens when connected to the 13mm tube as it might fall off. However with care it works fine and considering the price point compared to an official Canon set it is worth the bother. As I said before, the electronic contacts work and the cameras focus and exposure work, well worth the money but I do wish thar the 13mm tube would connect to the lens more securely, the 21mm and the 31 latch in place and work better than I expected.

Feels like a cheap toy; but at this price I didn't expect the best. That said, it does what it promises and you can do extreme close up photography using it. However, I wasn't able to get the biggest tube to work. It could just be my lens (Sigma Art 18-35); but even so, I didn't see the need to get any closer than I could using the other two. The auto-focus worked for me.Combining the smaller two tubes, I had to get within 1/4" inch of my subject and flood it with light from the side because the camera was casting a shadow on it.The Andoer is good for occasional fun or a cheap alternative to purchasing an expensive macro lens if you only have an occasional need for macro photography.

Great items. I stack them all together with my lenses. Can't remember off hand which lenses I have but will update if possible. Using all 3 tubes will get you closer but the focus will be blurred around the edges. Works really well and the price is inexpensive. AF does work but with all three tubes stacked and a telephoto lens it may struggle a bit so I use Manual Focus. No problem using AF with one/ two tubes. They are light weight and seem a bit flimsy but I have taken them off / put them on many many times and are holding up just fine. Very pleased with my purchase.

I would not purchase again. Results are good (for a beginner without much to compare), especially for price. I have the rebel t7i and it causes errors with the camera--each time I remove tubes I have to pull battery and restart. Minor inconvenience but I am worried it won't turn back on one day. My opinion is spend a little more in order to possibly avoid this problem, as I probably will sooner than later.

So, other reviews kind of threw me off when I was looking at these. But for $16, I figured it was worth trying out. Are they cheap-feeling plastic on the inside? Yes. Does it matter that much? Not really. Are AF connections needed? Absolutely. Especially if you're shooting with STM lenses, the AF connections are a must if you want to be able to focus at all, manual or auto.At f/3 or wider, the depth of field is super thin and I recommend closing the aperture to at least f/5 to get more of your subject in focus and so viewers can get a better idea of what you took a photo of.By the way, one review talks about using all three together, you won't be using all three together; that's not how you use these. And yet another review here is obviously fake. These aren't lenses and you won't be taking portraits with these extension tubes on.

These tubes have worked perfectly for what I need them to do. I have no interest in autofocus or image stabilizing, but they fit on my camera and hold the lens securely. Im not a professional so for the price I think they add a significant amount a value and versatility to my kit.

Extention tubes are basic simple machines the operation of which is complicated by connecting to automatic features of lenses and cameras. This one connects to AF and AE of EOS EF cameras and does an amazing job of it. Well constructed and light.

Two of the three tubes do not make electrical connection. So af doesn’t work. Would not recommend
