Combining 16 elements with 6 ED glass and a 12-blade aperture, this lens delivers edge-to-edge sharpness and smooth F1.8 bokeh suitable for 60MP sensors. Its aerospace-grade aluminum body features full weather sealing, a declicked control ring, and dual FN buttons for silent, precise operation. This is best for portrait and studio photographers needing a durable, optically refined 135mm prime with modern STM autofocus on Nikon Z cameras.
