Super-Multi-Coated MACRO-TAKUMAR 100mm f/4 — Optical design provides corner-to-corner excellence in performance at extreme close-up extensions that yield 1:2 and 1:1 image magnifications. Main advantage over Super-Multi-Coated MACRO-TAKUMAR 1:4/50 lens is the longer focal length permitting more working room for lighting placement and improved perspective with small three-dimensional objects; especially advantageous in opthalmology and oral surgery. Can be used as a moderate tele-lens in general photography. Optical contrast is high. Magnification scale on lens.1
Distance engravings in yellow (metres) and blue (feet); red IR marker; special engravings (in white) for image ratio.
The same optical design as the Bellows-Takumar 1:4/100 and the Super-Multi-Coated Bellows-TAKUMAR 1:4/100 lenses.
