Pros:

You can get much closer
Works with both EF-S and EF lenses
Auto focus still functions perfectly
Takes up very little room in your camera bag
Item looks about 3 times as large in photo using 17-40 Canon F/4 Lens

Cons:

A little tight to put on and take off of lens
Can no longer focus very far away let alone infinity

Review:

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!!!

As a photographer, I have been taking photos and improving my range of abilities over the years. The one thing that I wanted to work on most though was macro photography. Unfortunately most *good* macro lenses are quite expensive, running anywhere from $600 to $1500. A colleague of mine suggested that I purchase a macro extension tube which would allow me to use my current camera lenses AS macro lenses, so I started researching my options.

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!

I received the extension tube(s) a couple of weeks ago, they are wonderful. They work as expected, the AF works perfectly. What is especially great, about the Canon extension tubes is, you can use the EF-S lenses as well as the EF lenses. Other brands will not allow you to do that.

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 Polaroid Canon EOS Macro Extension Tube Set For Extreme Close Up Photography AND the Canon EF 12 II Extension Tube For EOS Digital Cameras 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

You can focus closer than without it, but you lose the ability to focus all the way to infinity. AF and TTL work just as good as without this between the lens and body. If you are interested in macro work you may want to look at the 60mm or 100mm macro lens before buying this since they allow 1:1 reproduction without any special attachments.
