About the Panasonic AG-CX20 Compact 4K Camcorder
The AG-CX20 and AG-CX18 models camcorders feature state-of-the-art optical technology, in addition to a lightweight and compact chassis design that delivers increased mobility, and high-quality video production.

Wide angle zoom lens for precise shooting
The camcorders offer superior optical performance thanks to a powerful integrated 25mm[1] wide angle to 600mm[2] telephoto zoom lens, with 24x optical zoom. They feature a 4-Drive Lens System that operates each lens group independently, in addition to two manual focus rings.

All four cameras feature both Optical and Electric Image Stabilisation to detect and correct any unwanted camera shake through five axes, including rotational blurring. This is especially useful when shooting subjects from very high and low angles. All models provide superior focusing speed, stability, and tracking performance when shooting in both 4K and FHD, thanks to the Face Detection AF/AE feature that provides precise focusing and exposure for subjects.

Listening to the needs of the industry
Panasonic’s intimate knowledge of what directors and cinematographers require from high-performance camcorders when shooting on location have been reflected within the improvements made to all four models, further increasing usability and functionality.

Compact design for superior mobility
The unique design of all four models enables heat to be dispersed from the front panel thanks to a slimline fan. This increases reliability and enables the body to be as small as possible. The CX20 and CX18 include Panasonic’s VW-HU1 handle unit, featuring a two-channel XLR audio input and control, and bright, adjustable LED light for shooting in low light conditions. Users can also easily operate lens zoom from the handle unit.[1]

All four camcorders support multiple bit rates and formats for a variety of requirements. When configured for 10 bit recording with an HDMI output, all models deliver 4K 60p 4:2:2 output with an external recorder. All camcorders support the MOV, MP4 and AVCHD formats, whilst the CX20 supports the P2 MXF workflow.

High-sensitivity 1/2.5-type MOS sensor
Handles large 4K data at 60fps/50fps with high-speed readout, minimizing rolling shutter distortion when capturing moving subjects.

Wide-angle 25mm lens with 24x optical zoom
4-drive lens system supports 24x optical zoom, ranging from a wide-angle 25mm (35mm film equivalent) to a telephoto 600mm. i.ZOOM technology enabling up to 32x zoom in 4K and 48x in Full HD provides exceptional flexibility for shooting even in confined spaces.

4K High-precision Autofocus
Optimized for dynamic shooting conditions on location, this autofocus system prioritizes speed and tracking accuracy. The Micro-drive Focus unit ensures precise lens control for fast, smooth focusing. Sharp focus is reliably maintained even when subjects move from background to foreground..

Face Detection and Tracking AE/AF
Advanced Face Detection AE/AF automatically identifies and tracks human faces. Also, specific colours can be selected on the 3.5-inch touch LCD to enable Tracking AE/AF to follow people and other moving objects with increased accuracy.

5-axis Hybrid Stabilization
Five-axis Hybrid Stabilization corrects for camera shake in five axes: vertical, horizontal, and rotational. Using a gyro sensor that detects motion at 4,000 times per second, the stabilization engine delivers fast corrections. Combining optical and electronic stabilization, it ensures stable video when zooming in at high magnification and also when walking or shooting in low light.

Ball O.I.S
A ball-bearing mechanism reduces friction when the lens system drive unit operates. The lens moves smoothly when zooming and delicately compensates for shake caused by small vibrations.

Built-in ND Filter
The built-in ND filter (1/4, 1/16, 1/64, CLEAR) adjusts incoming light levels to suit the shooting environment. The filter can be used to prevent resolution loss caused by excessive aperture reduction (diffraction) and supports a wide aperture for sharp images with a shallow depth of field.

Efficient Heat Dissipation
The image sensor typically heats up significantly as it collects external light through the lens, and its temperature rises further during high-speed 4K/60p signal processing, so an advanced, highly efficient heat dissipation design is employed to maintain stable performance under such conditions.

Venus Engine
The Venus Engine features a new image processing system capable of rapidly handling large 4K/60p datasets for exceptional image quality. It also offers advanced image correction features to enhance creative video production. Internal recording supports resolutions up to 4K 29.97p and Full HD 59.94p in 4:2:2 10-bit.

HEVC 4:2:0 10-bit Recording
Using the highly efficient new HEVC codec, the camcorder supports high-bitrate recording, including: 200 Mbps LongGOP (59.94p, 4:2:0 10-bit, MOV), 150 Mbps LongGOP (29.97p, 4:2:0 10-bit, MOV), 100 Mbps LongGOP (59.94p, 4:2:0 10-bit, MOV/MP4), and 72 Mbps LongGOP (29.97p, 4:2:0 10-bit, MP4).

4:2:2 10-bit Internal Recording / HDMI Output
Internal recording on SD cards supports 4:2:2 10-bit LongGOP UHD 29.97p/25p (150 Mbps) and Full HD 59.94p/50p (100 Mbps). Enabling 10-bit recording activates 4K/60p 4:2:2 10-bit HDMI output, ideal for capturing high-quality video from external recorders.

Advanced File Management with MOV File System
Using the same system as Panasonic’s AG-CX350, this camcorder automatically generates 20-character filenames for simplified clip management. It also maintains compatibility with traditional AVCHD recording formats.

Super Slow-motion Shooting
ICapture slow-motion video in Full HD mode at 120fps (59.94Hz) or 100fps (50Hz). The system supports 10-bit recording and delivers full-frame images without cropping, even at high frame rates. Autofocus remains active during super slow-motion shooting.

Infrared (IR) Shooting
The IR cut filter can be toggled ON/OFF and assigned to a user button. Disabling the filter allows shooting in low-light conditions using commercially available IR illuminators (recommended: 850nm IR illuminator).

Enhanced Skin Tones
The Skin Detail function refines skin tones for a softer and more natural appearance, which is especially beneficial for close-up shots.

Edge Enhancement
Master Detail makes it possible to fine tune the edge sharpness of entire images.

Flexible Gamma
Select from eight gamma modes, including CINE-LIKE developed with Panasonic’s expertise in VARICAM cinema cameras and FILM-LIKE for film-like gradation. The various modes offer a wide range of cinematic expression.

Customizable Scenes
Shooting can be tailors to specific conditions using six professional-grade presets: Standard, Fluorescent Lighting, Spark, Still-like, Cinema-like with contrast, and Cinema-like with dynamic range. Settings can be customized and saved in the camcorder for future use.
