Adding a New Version to the CJ18ex7.6B Series of Lenses

The CJ18ex7.6B KASE offers customers the same optical lens and electronic drive unit features as the existing CJ18ex7.6B IASE S/IRSE S lenses to those who do not need a 2x extender.

4K Optical Performance

The portable CJ18ex7.6B KASE 4K UHD lens was developed using our exclusive optical design technology to achieve superb optical performance, with 4K resolving power and high contrast from the center of the screen to the edges. High index optical glass materials, each having unique dispersion characteristics, help minimize chromatic aberrations and geometric distortion. Lens element surface accuracy has been improved significantly over HDTV lenses contributing to the enhanced Modulation Transfer Function (MTF) performance required of 4K imagery. New multi-layer optical coatings combined with new deposition processes produce a deeper black reproduction that is important to HDR imaging.

Minimized Chromatic Aberration

An optimized arrangement of fluorite and UD glass help minimize chromatic aberration, increasing image clarity with reduced color fringing on edges.

Reduced Ghosting

Special coatings and an internal lens barrel designed to prevent reflection result in clean black reproduction, less ghosting and flaring, sustaining high-tonality images that support HDR.

Compact and Lightweight

Weighing only 3.7 lbs. and measuring 6.3" (W) x 4.1" (H) x 8.1" (L), the portable CJ18ex7.6B KASE 4K UHD lens is similar in size to our 2/3" HD lenses, while delivering 4K performance and offering the mobility demanded in the reporting and documentary fields. The lens features the optimum construction and high durability of a conventional HD lens, while offering the same shooting style as that of existing 2/3" HD lenses.

The center of gravity is close to the mount, lessening strain on the hands and elbows of the camera operator. The ergonomic form factor creates a user-friendly design, including an ergonomic grip design for a comfortable feel during operation, helping to reduce fatigue and make it easy to move the camera about. The lens is sure to satisfy with its high-level combination of excellent specifications, enhanced optical performance and outstanding usability.
