A very simple way to make life-size copies with a normal 50mm lens. The free working distance between the subject and front of the lens is approximately 55mm, So lighting can be accomplished with a conventional light source. Available in sizes 49, 52, 55 and 58mm

Both the glass and the bezel are thick on this lens, about twice the thickness of the typical filter. It is threaded on both the front and rear.
Has being a great atachment for macro on a tamron 28-80mm telezoom lense
If you need super high resolution and/or wide depth of field, this product is not for you. But, if you want excellent close-ups of flat or "shallow 3D" objects, this filter is about one-tenth the cost of a close-up lens!
