Canon EF 25 II Extension Tube Reviews

The-digital-picture reviews the Canon EF 25 II Extension Tube and writes;
“The Canon EF 25mm Extension Tube II is updated to be fully compatible with Canon Digital EF-S lenses, as well as standard photo EF and TS-E lenses. Autofocus (except on TS-E lenses of course) and auto exposure are maintained when using these compatible lenses. There is some light lost when using extension tubes – the more extension used, the more light is lost. Functioning auto exposure will take care of correcting the exposure for you. “

Excellent piece of empty space | Rating: ★★★★★
“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… 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.” – by Kevin P. Barry

It works | Rating: ★★★★★
“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. “ – by Frank Doherty

Works as Advertised | Rating: ★★★★★
“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. “ – by Brian Koch

Worth the money, | Rating: ★★★★★
“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. “ – by M. Barrera

a little much, | Rating: ★★★★★
“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. “ – by Tommy J. Meyer

“Works pretty well. Let’s you focus alot closer than normal. The build is pretty good, although I wish it was just a tad bit more snug. It comes with a nice table that shows you the min/max focus distances for all the Canon lenses with this tube attached. Comes in handy. “ – by Wade

25 II Extension Tube | Rating: ★★★★☆
“This is an amazing extension tube and a great way to reduce the distance between you and your subject. I tried many closeup shots and found really handy to get close to the submit. Since it creates a gap between your lens and the camera, the AF and getting the right focus distance can be a challenging job. However, once you have figured out the right distance you can do wonders with this extension.” – by Amitabh Saikia

“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! “ – by Paul Larson

WOW, WOW AND WOW…..Real macro | Rating: ★★★★★
“Exellent piece or art for really macro users, i have this atached to a 60mm macro and get much closer pics, check the pics i have posted here at amazon and you will see what i’m talking about, i really recommend it, also, if you are taking picture of a fly for exemple, some times they dont let you get really close, so, the extension tube solves this problem too. thanks and enjoy” – by J.
