I've had these for a few years now. They're built really well, and in all this time they have developed absolutely no signs of wear.

Tubes are really pretty basic in construction. There are no glass elements, just mounts on each end and a pass-through for the lens data terminals. These are well-built, and as such they fulfill their intended purpose - that being that you now have an easy, less messy alternative to taping a cardboard toilet paper tube between your lens and camera body (and yes, you can do that if you want to go the low-tech route. Just make sure you seal the light leaks!) Any other issues are likely to be caused by a misunderstanding of the tube's purpose, not by the tube itself.

There seems to be a lot of confusion regarding extension tubes, based on some of the reviews I've read. While it would be difficult, without diagrams, to explain exactly how an extension tube works and the effect it has on focus distance and magnification, I can at least try to help with some of the problems people seem to be experiencing in these reviews.

1) All of the Kenko tubes sold under this listing will fill both EF and EF-S lens mounts. A number of years ago, this was not the case, and my first point was actually discussing how to tell the difference. Since the point is 100% obsolete now, I've removed it to clean up this long review a little. The original is visible in the comments in a comment dated May 8, 2014.

2) Extension tubes do not "magnify", technically. They increase the distance between the lens and the sensor. Imagine a projector sitting a foot from the wall, projecting an image on that wall. Using a pen, you outline the outer edge of that projected image on the wall. That's the outline of your "sensor". The image fills the "sensor".

Got this yesterday, tried it with a Canon EF 50mm f1.4 USM Medium Telephoto Lens for Canon SLR Cameras and Canon EOS 30D 8.2MP Digital SLR Camera (Body Only)... With the first two extension tubes, the results are amazing; with that setup you need to be about 4 cm (1.6" for you non metric people) from the subject; we're talking iris closeups here.

I thought about this for a long time because of the price, but it's well made, sturdy, lets you use autofocus if the lens allows it: I was unable to focus with a wide angle Canon 10-22, but that's just 'em laws of optical nature, and I need to fiddle a lot more with it.

Highly recommended if you feel drawn towards macro but don't feel like forking over lots of $$ for a macro lens; lighting is certainly an issue as you're very close to the subject, but may not warrant a macro flash like Canon MR-14EX Macro Ring Lite for 5D, 1Ds, 20D, 30D, G2, G3, G5, G6, Pro 1 & Rebel XT or Sigma Flash Macro Ring EM-140 DG for Canon SLR Cameras... And you will need to use a tripod.

Why not 5 stars? It's still a lot of money.

I've been reading over some of the negative reviews on these Kenko Extension Tubes, and I think some people have the wrong idea about what these things do. They get you closer to your subject...that's all. They don't magnify the telephoto end of your lens, like a 1.4x or 2.0x teleconverter would. They just allow you to get closer, so your subject is bigger in the lens. What you give up for this is the ability to focus farther away. Plus your depth of field, even at f/16 or f/22, is going to be measured in fractions of an inch, not feet or yards. You also lose light, about 2 or 3 stops depending on how many tubes you use. What you retain is image quality, which in my opinion is the most important thing.

Kenko has made a nice product here. These tubes are well-built and fit snugly on my camera. When I used my 70-200mm f/4 L, I noticed no sag or play at all. All electronic functions worked as they should, including aperture and auto-focus. Don't expect auto-focus to work as quickly as normal, though, and I believe most people would find it easier to just use manual focus. That's normal with any extension tubes.

If you understand how extension tubes work, you won't be disappointed with these Kenkos.

I was initially hesitant to purchase this simply because I had already made my own extension tube out of PVC pipe, a body cap, and a lens rear cap. Obviously, the one I made has some drawbacks (No autofocus, had to reset the aperture manually before attaching everything) but the question that kept occurring to me was whether or not these Kenko tubes were really worth the price, considering what a simple thing they are doing. The truth is, I'm still very glad I bought them. As simple as they are, you just aren't going to be able to reproduce the same functionality and build quality yourself for less money, and if you can then stop reading this and go do that. For the other 99% of us, these tubes are wonderful.

-Turn any lens into a macro lens. Get as close or as far away as you want, using the 7 effectively different combinations of the three tubes.

-Change aperture settings on the fly as you normally would do!

-Maintains the ability to autofocus in all but the most extreme macro situations.

-Great build quality! Even with all three tubes in use, the mount is very stable and holds very firm. I anticipated some play in them but cannot feel any wobble at all.

A great investment to make, since you will be able to use them in combination with ANY EF lens you have or will have in the future.

Check the image section for a couple images I took with my these tubes and my Canon 50mm EF prime 1.4f lens.
