100mm · f/3.5
The Yashica ML 100mm f/3.5 macro is a highly regarded lens in Yashica circles, often compared favorably to the Zeiss Makro-Planar 100mm f/2 for sharpness wide open (MFlenses). It is blisteringly sharp with even illumination, smooth operation, and an all-metal build. A weakness is that it requires two extension tubes to reach 1:1 macro, unlike some competitors. It suits macro and portrait photographers seeking a compact, high-quality alternative to Zeiss, especially at a good price.
