Watson zoom lens and mounting skid for the Pye Mk3 Television Camera

This is an early picture of the lens dated circa 1952 and the lens is further away from the camera than later zoom lenses as it uses an existing lens as part of the optical system.

The later production lens had a zoom range of 5:1 with the option of changing the rear element to give a different range. This early lens may be less than 5:1?

 

A report in Wireless World July 1949 page 250 describes the first use of the "Watson" zoom lens at the Cup Final held at Wembley Stadium. (but not on the Pye Mk3 as it was not introduced until 1951)
