A unique manual-focus lens designed solely for macro shooting, between life-size (1x) and 5x life-size – at its most magnification, you'll fill a 35mm frame with a grain of rice. Compatible with the Macro Ring nonfat s and new Macro Twin Lite, it eliminates the requirement for awkward bellows accessories for several macro shooters. A floating system preserves optical quality at totally different focusing distances, and options a UD-glass component.
