 "Olympus EX-25 Macro Extension Tube" 2010-06-08
By Candace A. Barry
I am impressed with this product. It takes a bit of getting used to being so close to the subject but the details revealed are amazing.
It's easy to use and well made. I wish I had bought it last summer when I first looked at it.

Made in Japan. Well constructed. Kind of expensive. I guess you get what you pay for.

An extension tube allows any lens to be mounted on its camera so that it will focus over a range much closer than normal, thus increasing the magnification, and it does this without adding optical elements. The thicker the extension tube, the closer the focus range will shift. In this case Olympus has chosen the length to bring the magnification of its 50mm f2 Macro lens to 1:1, meaning that the field of view at closest focus will be about 13 X 17 mm. The tube is beautifully made, and has the weatherproofing of the better classes of Olympus lenses. Be sure to keep it well sealed against dust when not in use, and put the two lens covers together to keep dust out of them. Some lenses are not designed to be optimally sharp or distortion free at close distances, but the tube will fit perfectly and maintain the automatic functions with all the Olympus lenses, and for that matter, all the E-series cameras.


 "What are you going to use this for?" 2010-03-01
By bdgilfry@wildchildpublishing.com (California)
If you're planning on shooting flat items, stamps, coins, smashed bugs, this works ideally, especially coupled with Olympic's 50mm lens (and of course, fits many others).

The biggest drawback is that your depth of field will be razor thin, even at f8. There is no glass here, so if you use a good ZD lens, you'll get all the magnifying benefits of that lens times two.

This will yield pretty good results if you use a ring flash, and you will almost always need a tripod. With those, you will discover a whole new world, nearly too small for the naked eye to see.


 "Works great but be careful!" 2009-09-10
By Lee Brilliant (Logan, Utah)
I do a fair amount of industrial type macro shooting to things down to 1/1000 of an inch. I use a modified copy stand and a Nikon bellows and 50mm reversed lens. I bought this to try in the moderate macro range and it works well but BE CAREFUL! What they don't tell you is that you cannot use it much below 45mm focal length because of the retro-focal design the subject will have to be BEHIND the front of the lens. I use an 18-180 most of the time so half the focal length is unusable and I cannot use my wide angle at all. But taking that into consideration, it works very well at 50mm and above. So don't even think of getting a 35mm macro for use with this extension tube. That said, I am still learning how to use it best and plan to couple it with the 50mm macro lens. Should be a great combo. I would like to see a set of such extensions: say a 10mm and a 40mm for more flexibility.
