This aperture series was shot to explore contrast and flare control as well as bokeh.
To my eye, the quality of the Leica M240 sensor and the Zeiss ZM 85mm f/4 Tele-Tessar are a cut above the Olympus E-M1 and Fujifilm X-T1 on the same scene (and with the same equivalent 85mm field of view). Full frame rocks; Zeiss rocks.
