The KJ17ex7.7B and the HDgc line of lens have been specifically
designed for low cost acquisition and this lens is particularly
well suited to reality TV, newsgathering and other low budget HD
productions.
The KJ17ex7.7B's short 7.7 mm focal length translates to a 63.9
degree horizontal angle of view for the 16:9 HD image format.
Combined with a focal range that has been extended to now cover a
range from 7.7mm to 131mm (and 262mm with extender) this lens
offers unsurpassed operational capabilities in a compact package
weighing less than 1.62kg. Focus breathing is significantly
reduced. The maximum relative aperture is F1.9 which, combined with
the typically F-10/11 sensitivity specifications of the
contemporary HD ENG cameras, ensures excellent video pictures in
very low light environments.
Newly developed optical materials combined with the very latest
lens element design innovations and multilayer coatings - that
produce an unsurpassed pristine imaging system for the most
discerning production team.
