Product Description
Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.The extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.The Kenko Auto Extension Tube Set contains three tubes of different length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any combination to obtain the desired magnification.Kenko’s Auto … More >>

I’m not overly happy with this purchase. This is not necessarily the fault of the product. I was hoping it would fill a hole in my lens collection, but it does not. I own a 50mm Sigma macro lens, which gives me 1:1 macro capabilities. It is a fine lens for the cost. However, due to the focal length, the focus distance is far too short for many applications. I was hoping that these extension tubes would allow me to move back with my 70-200 f4L and still get some macro capabilities, however, with the limited depth of field, I have not gained much.

At first I didn’t think it worked, but then I realized I just had to get REALLY close to the subject (like an inch or two.) They work on a 50mm F1.8 and a 35mm F2, but not on the 17-85mm F4-5.6. Check compatibility before buying.
I’d update my rating to 4 stars.

I bought this after reading that it would take my Canon 100 mm macro lens from a 1-1 to a 2.2-1 magnification. It does not. It barely gets the image any closer at all. What it does do is force the suject closer to the camera for any lens. So if you want to use a 300 mm telephoto zoom lens in your livingroom, it’s great. Personally for indoor shots I have shorter lenses.

I’ve had these tubes for a few weeks now and am very happy with it…I really wanted to get the Canon 100 2.8 Macro but since I was new to Macro, I thought this might be the less expensive way to get me started into Macro..
What I really don’t like about these tubes is the focusing….I’ve been having a focusing problem, but perhaps thats my lack of expertise. Another thing I don’t like is the complete frame is never sharp. Just the center is sharp. Yes, I do love the “bokeh” but, I’d really love to get more of the shot into focus. Again, perhaps thats my inexperience, but I really don’t think so. But, yes, I’d emphatically recommend these Kenko extension tubes…
