The lens is equipped with the E-Mount and is compatible with large area-scan and line-scan sensors with an image circle of up to 43 mm and a pixel size starting at 2.8 µm. The aperture can be adjusted on the lens by 1/3 f-stops from F2.8 to F22. The locking and torque of the aperture ring are designed to prevent accidental adjustment due to vibrations or the movement.
