A lens of 2-element, 2-group construction and a +10 diopter rating. Resolution is outstanding and focusing is possible at 10cm for super close-ups of insects, flowers and other small objects.
The magnification is about 1:2 with a 50mm standard lens (35mm camera), roughly equivalents to a 100mm telephoto lens. The lens should be stopped down as much as possible to get maximum depth-of-field.

I purchased an used 2000 Canon G1. It is hard to find any lens for it. The first I purchased caused major vignetting. This Hoya does not. I will be purchasing another one. The only drawback is it will pop out as the threads of the step down ring do not screw in smoothly.
