The result of using extension tubes is that the distance from the back of the lens to the film surface is longer, which means you can take photographs at shorter distances to the subject. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits. This updated version II is now also fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses.

Since I was working with a Canon 40D body, as well as a variety of lenses, I needed an extension tube that supported both the EF and EF-S lens types. This Canon EF 12 II provides that functionality, as well as full electronic pass-through for all auto-focus and metering features of the lenses.
For table-top & desk-top macro work, I found that this extension tube works beautifully with the Canon EF-S 18-55mm with the lens extended to the full 55mm.
If I am outside walking around, I find that the Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens for Canon SLR Cameras works very well for taking macro photographs of flowers and other close-up objects.
A note to consider, if you are using a macro extension tube, you generally can NOT focus to infinity any longer. So this item is for use while taking macro photographs or nearby objects ONLY.
I've also uploaded a macro image in the gallery of this product, showing how well this macro tube works!
As a side note, if you want to get even CLOSER to your subject, pick up the OTHER Canon extension, the Canon EF 25 II Extension Tube for EOS Digital Cameras , and combine the 12mm and the 25mm into a 37mm tube! It works VERY well!
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!
Love it! Works best when you can correct for heavy vignetting in Ps with lens profile adjustment. Keep in mind, the focus area is razor thin.
The first time I used it the focusing connection was balky, but since then it has been great.
I carry it in my pocket when I am working, and yet it still works great. I had used the longer extension tube, but that was way too long. I find it most useful with my 50mm on my 5DMii. I haven't found an application needing this with the 135mm.
