Dedicated to aerial photography, this specialized version of the HC 210mm f/4 Lens from Hasselblad is a telephoto prime offering a 19° angle of view. Differing from the standard lens range, this lens features a secure locking mount to significantly reduce unwanted vibrations and flexing on the lens-camera interface, and the rigid mount also ensures the image and sensor planes remain perfectly parallel at all times. Additionally, this lens has a locked focus position at infinity as well as dedicated firmware to close the central shutter and aperture mechanism to their working positions when power is applied to the camera system.
The lens employs a 10 elements in six groups optical design to control aberrations and distortions, as well as deliver a high degree of sharpness, clarity, and illumination from edge to edge. Additionally, the central shutter unit affords a shutter speed range up to 1/4000 sec.
