Introducing the Canon CJ15ex4.3B Wide Angle Broadcast Lens
Delivering the high optical performance of Canon’s UHDxs series, the CJ15ex4.3B broadcast lens possesses an industry-leading wide-focal length of 4.3m... read morem and best-in-class maximum focal length of 65mm (130mm with built-in 2X extender), making it ideal for producing high-quality video for a variety of needs including sports broadcasting and electronic newsgathering. Through the optimal placement of fluorite, UD and Super UD lenses in a multi-group optical configuration developed by Canon, the CJ15ex4.3B possesses excellent correction of situations such as color bleeding and chromatic aberration. In addition, Canon’s proprietary Air Sphere Coating (ASC) helps reduce flaring and ghosting and provides great visual expression with rich gradation, which is ideal for HDR and WCG shooting. The CJ15ex4.3B is the first portable broadcast lens to feature Air Sphere Coating, which originated with Canon’s EF-mount photography lenses.
4K Optical Performance and Improved HD Imaging
The portable CJ15ex4.3B 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. As part of our UHDxs family, this lens represents Canon’s highest class of broadcast lens offerings. In addition to capturing impressive 4K content, the CJ15ex4.3B lens will significantly enhance current HDTV optical imaging performance while potentially future-proofing for the longer term, making it ideal for those seeking a new lens for contemporary HDTV production – while also anticipating a future shift to 4K production.
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. Multi-layer optical coatings combined with strategic deposition processes help ensure a deep black reproduction that is central to HDR imaging.
Extreme Wide Angle 4.3mm with Class Leading 15x1 Zoom and Built-in 2x Extender
The CJ15ex4.3B 4K UHD wide-angle portable lens offers the world's shortest focal length of 4.3mm*. This makes it possible to create images with extreme 96.3 degree wide angles of view, with the shortest focal length for a 2/3" 4K lens. Additionally, this lens offers the longest telephoto performance in its class with a 15x zoom* ratio enabling shots up to 65mm, and for even greater flexibility the built-in 2x extender can increase that further to a super telephoto 130mm focal length.
