FotodioX MACRO-TUBE-AUTO-EOS31 overview

  • 1Description

The 31mm Pro Auto Macro Extension Tube from Fotodiox is suitable for use with Canon EOS EF & EF-S Lenses for extreme close-up. It is an automatic tube that is able to communicate all electronic functions from the lens to camera including autofocus and auto-exposure. No other optical components are added, so the image will preserve the original optical properties of the lens.

The lens transforms into a macro lens while maintaining its optical quality. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created.

Any combination of tubes can be used for various reproduction ratios
No optical insert - maintains lens optical quality
Maintains the electronic functions of the lens, including auto-focus and auto-exposure
Matte black color

    FotodioX MACRO-TUBE-AUTO-EOS31 reviews

    Pro Auto Macro Extension Tube for Canon EF & EF-S Lenses (31mm) is rated 3.4 out of 5 by 7.
    Rated 5 out of 5 by from Extremely Shallow DOF The FotodioX Pro Macro Extension Tube is well built, better than I expected even. I purchased the 31mm tube and if I was able to do it over again I would have bought the 24mm instead. The 31mm works great with my 50mm prime lens, and would assume it would work on lenses with longer focal lengths. What the 31mm tube does not do is work on lenses with wider/shorter focal lengths. I find that the minimum focus distance is too close (literally within the length of the lens itself) and cannot be used. This does not detract at all from the value or quality of the tube though, there is a reason there are varying lengths available.

    Rated 1 out of 5 by from Release button housing snaps at screw on all FotoDiox tubes I bought this and the 13mm. Both had the same problem/defect: The housing for the release button that juts out from the tube exterior snapped because it was cheap plastic. They were both snapped right at the screw (that holds it into place), cheap plastic. In my eyes this is a catastrophic failure (so 1 star) meaning that, the button can become inoperable, fly off and the extension tube can get permenently attached to your fancy expensive lens in the middle of a shoot and will require tooling to remove it, destroying the tube in the process and possibly damaging your equipment. Don't know how my 13mm snapped, but my 31mm tube CAME broken at the same spot. Too bad, everything else seemed in order connections worked fine. :(

    Rated 5 out of 5 by from Great Buy For Introduction To Macro Photography I typically don't review products until I've had time to test them out thoroughly, but this extention tube really impressed me on the first day. I take a lot of floral shots and want to explore macro photography. I opted for this extension rather than a dedicated lens because of the price just to get me started. As a previous reviewer said, the connection is a little snug, but it worked for me right out of the box as it should. Just be sure to line up the red dots. For this test, I used a Canon EOS 7D with the 28mm - 135mm kit lens (purchased recently from B&H), tripod, adjustable camera platform, 2 sec. timer to minimize vibration, manual focus (but auto-focus works just fine) and basic household flourescent lighting that simulates sunlight. Of course, I had to take the standard quarter test shots. The first three shots were all taken at the closest 135mm wide open at f5.6 (focusing bottom, center and top of the coin) and the last shot at f36 focused on the center. At f36 the center was sharp while the rest of the coin was in focus, it still wasn't tack sharp. 50mm was as far out as I could go while mantining focus. Top and bottom coin shots are uploaded as I can only attach two images. I haven't had it long enough to say if it's durable, but it's a sturdy product. Overall, it does exactly as it states and I'm very pleased with my purchase. For just a bit over double the price, I wish I would've purchased the set of three that also included the 13mm and 21mm.

    Rated 4 out of 5 by from Works well...now Works well....now that I fixed it. When it arrived, I could tell it had been sitting on a shelf for a while - dusty, box a little tattered. First time I mounted it to the camera I got and error, something to the effect of: can't connect to the lens, clean the contacts Cleaned them: same error. Then I had a really good look at the contacts on the extension tube. The one end, the end that your lens mounts to, has spring-loaded contacts. A few were binding and not popped up all the way. I used a metal mechanical pencil to massage the spring - worked like a charm. Mounted and unmounted this tube lots, and no more errors. It wasn't damaged, I don't think, just a mechanical glitch. Mounting is not perfect - a bit tight. I deducted 1 star for that. The mounting springs are stiff but that's not a big deal. Just go easy. Construction is just fine - all metal including the mounts. With my EF 50 1.4 on FF, with a 500D Closeup mounted as well, I am getting near 1:1. All I can say is: time to start learning how to focus-stack! I bought this because I can't afford a dedicated macro lens ($600 to $1200. Coupled with a 500D Closeup lens, this is a good setup and is capable of getting close. If you can afford a dedicated macro lens, buy it. It will be more convenient to use than this. I have 2 kids and when we are out and about, I have to take off the extension tube if I want to shoot them (tubes severely limit your focus range). When I want to do a macro I have to remount the tube and lens. Not the biggest deal in the world, but you risk getting floaties in your chamber. Bottom line: great price, 31mm of extension, works just like it should, be prepared to sacrifice some functionality

    Rated 5 out of 5 by from Well worth it!! I paired this with my 5D Mark3 and 100mm Canon Macro. This tube fits nice and works very well. Easy to take on and off. Adds needed magnification when needed. For the price, look no further.

    Rated 2 out of 5 by from Not secure These work but I had to upgrade to a better quality product. Left a gap between the tubes and lens. I was holding my lens to ensure it didn't disconnect. Tried it on several Canon lens. Not recommended.

    Rated 2 out of 5 by from Disappointed I works, but it does not mount as smoothly as it should. I am going to get a Canon tube.
