Though they all work, these tubes made by Canon fit perfectly!

I have always loved macro photography but cant justify spending 900 on a macro lens at the moment.

Folks want to see details that you really can't capture without getting up close.

I bought the extension tube to allow me to get closer pictures of flowers. While it is a bit expensive, it does its job. I have been able to take several very creative close-ups that I couldn't do with just my 100mm Canon macro lens. I would certainly buy it again. I use it all the time.

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.

I bought an EF 25 II extension tube on eBay more than a year ago and took a few pictures that I was not happy with. Since then it sat in my camera bag. Now a year later and a lot more experienced with photography (bought an expensive camera, 5D, and three `L' lenses including an EF 100mm macro f/2.8 L) I decided to get started with macro photography.

I read Amazon reviews for my 100mm macro L and someone had posted that you could save a bundle by getting a lens extension which will give similar results. I said to myself `hey I have one of those in my closet'. So I took it out and started experimenting with it using my `L' lenses - I was afraid to put it on my 5D body (might damage it?) instead used my XSI Rebel.

It is tricky to take pictures with the extender but I got better and better and finally got a picture that is as good as my $1,000 macro, possibly better. I posted it so you can take a look - it is the bee on yellow and white flower.

Here is what I found is needed to get a good macro shot;

No wind to keep everything still

Camera must be held by some stable method - I don't see using a tripod with moving insects.
Bright sunny day (maybe use a flash?)

Fairly fast shutter speed - at least 1/250

High ISO to help with fast shutter

Stop down to f/11 or higher for depth of field

Manual focus

Zoom lens, in my case EF 70-200 F/4 L

The zoom lens is the key here, once you get the manual focus set, you can use the zoom ring for a quick and accurate final focus. The good focus along with good depth of field from the f11 or higher, and fast shutter will give good results.

The extender is harder to use than a macro lens and you have many more failures but it can work well.

If you like close up macro work then this is a necessity. It works great with my two macro lens, Canon EF-S macro and Sigma 150 macro, have also used it with my Canon 135L and 85 f/1.8 and have been very happy with the results. You do lose the ability to focus to infinity so it is primarily for macro work.

For a circle with a hole in it, this is well worth the money. Of course, you pay for the sturdiness of the piece, since poor build quality could definitely reduce the quality of your pictures. Don't be mislead by the description on Amazon, however. The site implies that this adds 25mm to your lens and that is it, whereas this will "macro-fy" your lenses. With this tube, my 28mm focuses from about 1-1.1" from the front of the lense, with a depth of field of a fraction of a mm at f/1.8. It's also strong enough to support my 200mm f/2.8L + 1.4x II, which is almost more than I can say for myself. My favorite use is in between my 85mm f/1.8 and 1.4x. I got stuck with a mark I, but I don't plan to use EF-S lenses anyway.

I have owned this tube for a few years. It is a great piece for close-up work however I find that it is somewhat extreme. You get really close up, which is great for some subjects but not so good for others.It is so close it's hard to focus on the entire subject sometimes. If you want extreme closeness, go for it. If you what a little more versatility, go with the 12 II version.

I have considered this purchase over the last year and after just using it for two weeks I wish I had bought it last year. It does make auto-focusing a little trickier, and you lose infinity, it is well worth the extra "trouble" in figuring it out. I bought it mainly for macro but last weekend I spent hours in my backyard using this with a Canon 100-400L to capture hummingbird pics. They turned out awesome!

First of all, I am giving the EF 25 II extension tube 3 stars not because it isn't great (it is), but because it provides a very low ratio of performance to price.

All extension tubes contain the same air and have the exact same impact on close-focus distance. Given this, it is a bit hard to justify the price of this extension tube given that it provides no better optical quality or any other photographic bonus than any other tube.

When comparing this tube to other, cheaper products, it is indeed more sturdy and does have the metal mounting flanges missing from some (but not all) of the cheaper competitors. It also has Canon's anti-reflective coating on the inside of the barrel, while most competitors are simply plain black plastic on the inside. However, for most users, this isn't going to matter at all as most modern lenses are good enough to not require the anti-reflective flocking and most kit is not heavy enough such that the sturdy nature of this tube will ever come into play.

I can only recommend this tube if 1) you are using really heavy kit without a tripod collar (perhaps you are shooting a 300/2.8 hand held) or if you are using one of Canon's larger telephotos. Most of the other brands cause IS instability when used with Canon's larger telephotos (verified on the 100-400L, 500/4, 600/4 and I suspect the 300/2.8 and 400/2.8). I am guessing that their contacts have a high enough resistance that occasionally the voltage running from the camera to the IS gyros drops below a certain threshold, thus forcing the gyros to park themselves. This results in what could best be described as IS stutter and makes photography difficult and (I suspect at least) will damage your IS mechanism in the long run.
