Overview

The Minolta Auto Bellows Rokkor 100mm f/4 Macro is a lightweight (388g) lens with 5 elements in 4 groups, noted for very low light falloff wide open (Rokkor Files). It offers greater working distance than 50mm macros, making it suitable for insects (Rokkor Files). However, the bellows combination is considered more ornamental than practical, lacking a tripod ring and causing imbalance with heavier lenses. It suits collectors and Minolta enthusiasts who appreciate its compact, delicate build, but it may see limited actual use.
