AIDA Imaging CS4K-3611V – 4K Varifocal 3.6-11mm Auto DC-Iris CS Mount Lens

Product Overview

The AIDA Imaging CS4K-3611V is a 4K-optimized varifocal CS mount lens with a 3.6–11mm focal range and automatic DC-iris control, designed as a precision optics upgrade for AIDA POV cameras and compatible fixed-installation camera systems. The varifocal design allows integrators to adjust the field of view without changing the physical camera position — a critical capability in rooms where camera placement options are constrained. Optimized for 4K sensor resolution, the CS4K-3611V delivers sharper, more detailed imagery than standard HD lenses when paired with 4K or high-resolution camera platforms, and the auto DC-iris maintains consistent exposure automatically in response to changing ambient light conditions.

Product Description

The CS4K-3611V addresses one of the most frequent practical limitations in fixed-camera installations: a single fixed focal length lens rarely produces the ideal field of view for every room size, camera mounting position, and viewing angle. With a 3.6–11mm varifocal range, the installer can dial in the exact horizontal field of view needed after the camera is physically mounted and the final position is confirmed. The 4K optimization ensures the lens passes the full resolution potential of 4K-capable sensors without introducing lens-related softness that would be visible at higher resolution outputs. The automatic DC-iris mechanism continuously adjusts the aperture based on incoming light level, maintaining consistent exposure in rooms with variable lighting — windows shifting from bright daylight to overcast, venues transitioning between pre-show, show, and post-show lighting states.

Key Features

• 4K-Optimized Optics — Resolves detail at 4K sensor resolution for high-resolution cameras and future-proof installations.
• 3.6–11mm Varifocal Range — Adjustable focal length allows field-of-view tuning after camera mounting, eliminating remounting for different room configurations.
• Automatic DC-Iris Control — Auto-adjusting aperture maintains consistent exposure in variable lighting environments.
• CS Mount Interface — Direct compatibility with AIDA POV cameras and the broad range of fixed-installation cameras using the CS mount standard.
• Improved Low-Light Performance — Auto DC-iris supports optimized aperture selection for lower-lux environments.
• Drop-In Upgrade — Replaces the 4mm lens shipped with AIDA cameras, adding varifocal flexibility and 4K resolution in the same C/CS mount footprint.
