Canon EF 12 II Extension Tube For EOS Digital Cameras

This canon EF-12 ll extension tube is great,work exacthly as I expected. I also bought the canon EF 25ll extension at same time. I love them. Thanks.

Considering it's just a spacer, it would be hard for this item to be exceptional. It enables super close-up photos; I'm happy with the results.

Great tube but wish I had bought the three tube kit from Kenko.

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!!!

Good product, does what it says it'll do. I was suprised how well it works.
