Fotga Macro AF Auto Focus Automatic Extension Tube Ring 13mm + 20mm + 36mm Set for Kenko Canon EF EF-S Lens

This product is a little disappointing. Generally, Fotga makes decent product, and these extension tubes are a bit more expensive than a whole lot of other ones.First, the description clearly states "metal automatic macro extension tubes". They are definitely plastic and are not metal. I specifically decided I am willing to pay more for these to get metal tubes, but unfortunately they are plastic... it's not really worth double the price of all other plastic tubes in that case.Second, the description also says "can be used in any combination". This is unfortunately also false. While each tube works on its own, when they are put all together as shown in the image (with the largest attached to the camera and the smallest attached to the lens, with the middle-sized tube in the middle), they do not work, and the camera shows an error with communicating with the lens in this configuration. I have figured out that I can put the smallest tube at the bottom (attached to the camera) with the middle-sized tube attached to the lens and the largest tube in the middle, but that is the only configuration where all 3 tubes work together. I inspected all the contacts and did not see anything specifically wrong. Your experience may vary, though judging by my tubes, it very likely might be worse and there may not be any configuration where all 3 tubes work together.Overall, this is not what I expected for this product.

Since I bought it, I haven't actually used it. Today I used it the first time. It causes camera (Canon EOS T5i) error: Error #0001 - can not read electronic information from lens. By inspection, I could see there was one small button inside the tube of the short one (13mm) did not jump out. Too bad quality. Don't waste your money.

Two of the three tubes works with my camera, but you get what you pay for I suppose.

I am pretty disappointed. 2 out of the 3 attachments work. But the largest one will not connect to my autofocus. I contacted the company for help. Sent them the pictures they asked for. I haven't heard back and just checked and my return window closed. I would not buy again and would not recommend this company. Save your money and buy elsewhere.

It works for Macro. But the quality left me in doubt. It looks fragile;

For the price this item is worth it ,being completely plastic you cannot handle the extension tube to rough.
