Overview

The TTArtisan 75mm f/1.5 is a modern remake of the legendary Zeiss Biotar 75mm f/1.5, offering strong center sharpness and a distinctive swirly bokeh effect. Its all-metal build and scalloped focus ring evoke vintage handling, but the M42 mount requires adapters, adding bulk. Weaknesses include rapid sharpness fall-off outside the center and potential need to re-clock the barrel. It suits photographers seeking character and unique rendering over perfect correction, especially on full-frame or medium format.
