Comparison of V-series lens coupling to the camera of 250 mm /5.6 lens above, and their latest version 110 mm f/2 FE lens (left) with both mechanical, and electronics contacts with the body. The mechanical coupling (at 6 o'clock) couples the charging operation in the camera with the lens, and orchestrates the firing sequence so the diaphragm closes down while the mirror goes up before firing of the shutter. The electronics contacts (9 o'clock) give aperture information to the electronics meter circuitry inside the camera.
