This product did not meet my needs. It attaches between the camera and whatever lens you want to use. I tried it on my T5i with a Canon EF-S 18-55mm IS STM lens. The product description on Amazon says "Canon EF 12 II Extension Tube For EOS Digital Cameras". My T5i qualifies completely as an "EOS Digital Camera". Subsequently, the product info on Amazon says "Retains all metering and AF functions with most CANON EF lenses". Silly me, I assumed that all of my camera/lens functionality would still be available. GUESS AGAIN! Autofocus does NOT work when using the product, and the zoom ability is also toasted! The product description on Amazon does not mention this gamebuster for cameras/lenses of my type. They must have meant somebody else’s EOS Digital Camera.I returned the product.I do not recommend trying it.

I know, seems expensive for a hole with a mount, but I have tried off brand extension tubes and the build quality is not the same. I'm mounting one of several L lenses (70-200mm/2.8 IS II, 50mm/1.2, 24-70mm/2.8) and I'm delighted with how precise these lenses mount on this tube. Autofocus works as it should and I'm not fist-gripping the thing to get it off like I have had to do with third party tubes. One actually would grab somewhere on the mount, and then when you applied pressure it clicked loudly as it loosened. NO THANK YOU, money well-spent with this Canon when you are mounting $6K worth of lenses on it.For wedding shooters: if you have a 50mm or a 24-70mm, this ring is all you need for Details shots. The 25mm ring is TOO close, I can't even use the 50mm with the 25mm extension if I want to keep my sunhood on, which I always do. You may not fill the frame with a quarter with this 12mm but for rings and jewelry, it's absolutely close enough, especially with the 1:4 Macro capability of the 24-70mm. I shoot a 5D3 and I can always crop in a touch if needed. No big deal losing a bit of pixel data for details shots, I haven't had a bride request a 40"x60" canvas wrap of the rings (yet), lol!

I find that it allows me to get more out of my current lenses and camera. Very nice item. Thanks.

My grandfather once told me that all cheeses were made in the same factory so it doesn't matter which cheddar, for example, you purchase. This isn't literally true, of course, but the point he was trying to make is that something that costs more isn't always better than a cheaper version of the same thing. With his voice in mind I purchased both the AND the and put them to the test to see which was the greater value. Here are my findings:1. I'm happy that I bought both.2. They decidedly do not represent different price points of the same thing. The fact that I originally thought they did only reflects my growing, yet still weak, expertise in the paraphernalia of macro photography.3. The Polaroid tube is made up of 7mm, 14mm, and 28mm lengths that can be used individually or in any combination.4. The Polaroid tube is just that...a tube, and supports no electronic connection between camera body and lens. In my book this is absolutely fine as long as what you are photographing is not moving and you have the time to make the necessary positional, exposure, and lighting corrections. Photographing jewelry in a static and controlled environment would be a good example.5. The Canon tube, more like a thick ring actually (The is a bit more tube-like.) is of a single fixed 12mm length and supports complete connectivity between camera and lens so that exposure and focusing are done as seamlessly with the EF 12 as without. This is a huge benefit if what you are trying to photograph is in a changing environment or moving. Macro photos of insects comes to mind. Yes, I actually did this while building lesson plans for my Biology class.So, while my experiment to determine relative value was a bit misguided, I did end up with two devices I use frequently and would be unhappy to part with. As I said, they are not 'of a kind' and have separate yet strong appeal. If the Canon tube is a cheese it would be a fine Brillat-Savarin while the Polaroid isn't a cheese at all, but a really nice set of pliers.

Pros:You can get much closerWorks with both EF-S and EF lensesAuto focus still functions perfectlyTakes up very little room in your camera bagItem looks about 3 times as large in photo using 17-40 Canon F/4 LensCons:A little tight to put on and take off of lensCan no longer focus very far away let alone infinityReview:I purchased this Extension tube so I could take better Macro photos without having to purchase an expensive Macro lens. I've got so many lenses already.I installed the tube between my Canon Rebel XTi and Canon 17-40 F/4 L lens and bang!!! Instant macro lens.A photo I had taken without the tube of a penny using the Canon 17-40 zoomed to 40mm gave a so so image. Putting the tube on allowed me to focus so close the penny filled almost the entire view finder. Looking at the penny image taken with the tube you can see little details I never noticed before like each and ever step and little details like the little FG on the lower right corner on the back of the penny.Verdict:I highly recommend it's worth every penny!!!
