Canon Extension Tube EF II Overview

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.

When using the camera's TTL metering system, no exposure compensation will be required (exposure compensation is required for handheld meters).

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.

Extension Tube EF 12 II is especially suited for close-focusing with wide-angle lenses. Compatible with all lenses, except 15mm f/2.8 fisheye, 14mm f/2.8L and MP-E 65mm f/2.8.

I hesitated buying this because I had an extension tube once and didn't like it. My main complaint was not being able to focus to infinity. I decided to take the plunge again, and that problem is still my main complaint - of course I knew this going in, so I'm trying to learn to live with it. The increase in close up ability was my main reason for buying it, and it works great for that purpose - at least on most of my lenses. Auto focus is a concern, because my eyesight isn't as good as it was a couple decades ago. But, I have used it on my Canon 100-400mm L zoom, with a 1.4x iii teleconverter, and it works fine. It also auto focuses on my 70-300mm IS II USM Canon lens. Auto focus does not work on my Tamron 18-400mm lens. It works on all three of my DSLR's - MK IV, 80D and 77D. Construction is very solid. I'm not sure how much I'll use it, but I'm going to hang onto it.

Fits perfectly

I bought this to replace the aftermarket extension tube that I was using to stack my Series III extenders together. Works just fine. May not be worth the big cost over third-party versions but it is nice knowing I'm using all Canon products.

Excellent for macro photo

Does what it does

It's wildflower season, and I found I wasn't able to get quite as close-in as I wanted with the 100 macro, so I added this guy. Did just what it's supposed to - brought down the minimum focusing distance. The 100 already has a paper-thin plane of focus, the tube only increases that effect. I didn't notice much in terms of f-stop loss that affected what I could work with. I like that it's Canon with that build quality and guaranteed electronic compatibility. See the focal plane at the moth's proboscis:

Makes my 70-200 focus closer so good for chasing butterflies and other small critters

I bought this to be able to photograph some old 35mm negatives and it worked perfectly. Most noticeably, the auto-focus was spot-on even that close. Personally, I feel much more confident using the Canon Extension Tube as opposed to other makes. I now have a way of digitizing negatives that costs so much less than the kind of scanner I would need for that kind of resolution. And, of course, B&H service was excellent as ever.

An extension tube such as this would only short the focusing distance of a lens and would not change the focal length.

Will this add some vignetting to my rokinon 8mm fisheye?

I only use the extension tube with Canon lenses at or above 50 mm of focal length. With an 8 mm lens the vignetting is almost guaranteed.

question

How is this extension going to affect my 24-105 f4, mounted on a 5D mk II? I will be doing jewelry photography and trying to figure out if I need to invest in a macro lens vs modifying the one mentioned above. Thank you! Still figuring it all out, I hope the question makes sense :)
Asked by: Anonymous
I'm afraid I have only used the extension tubes with macro lenses and the effect was to increase the magnification. I'm not sure if that will be the same effect for non-macro lenses.

question

Can I use this extension tube with a Sigma 17-50mm F2.8 EX DC OS HSM on full frame a DSLR without a vinaigrette effect?
Asked by: Anonymous
Technically you could mount the extension tube between the APS-C format lens you have and your full-frame camera, however we do no regularly encourage this combination as it will cause vignetting and will not be useful with the lens you mentioned above.

question

i recently purchase a efs10-22mm and thinking about adding Extension Tube EF 12 II would this extension allow less light in and what effect good or bad will it have on images?
Asked by: Don M.
You would not lose much light using the Canon Extension Tube EF 12 II on the Canon 10-22mm f/3.5-4.5 EF-S USM lens. The effect the extension tube would have on your image is you would lose infinity focus, however, it would allow you to focus closer on your subject for higher magnification for macro or close-up photography needs.
