Optoma BX-CTA10 Motorized Short Throw Zoom Lens

The Optoma BX-CTA10 is a motorized short-throw wide zoom lens created for immersive installations where the projector needs to sit a short distance from the screen. Its 1.3x zoom and full lens memory provide practical control over image setup. The memory system saves and quickly recalls zoom, focus, and lens-shift positions, while the supported image-size range extends from 50 to 500 inches. The lens is designed for use with Optoma ZK1320 and ZK1120 4K UHD+ projectors.

Ideal Use Cases

The BX-CTA10 is intended for immersive projection systems that require a comparatively short distance between the projector and screen. This makes it relevant when the installation layout does not accommodate a longer projector-to-screen distance or when the projector must be integrated close to the image surface. Its broad stated image-size range supports installations ranging from a 50-inch image to an expansive 500-inch presentation.

Full lens memory is particularly useful when an installation must return to established zoom, focus, and lens-shift positions. Instead of treating each optical parameter as an unrelated setup step, the lens can save those positions and recall them quickly. This capability suits systems where maintaining a defined optical configuration is important.

Why Choose This Model

The BX-CTA10 combines four clearly defined capabilities: short-throw placement, a 1.3x wide zoom range, full lens memory, and support for image sizes from 50 to 500 inches. Together, these features address both initial installation and subsequent operation. The zoom provides adjustment within the lens’s stated range, while lens memory preserves the selected zoom, focus, and lens-shift positions for quick recall.

Compatibility is also clearly identified. The lens is designed specifically for the Optoma ZK1320 and ZK1120, both described as 4K UHD+ projectors. Buyers building around either of these projector models can select the lens according to that stated pairing.

Installation and Integration

Installation begins with one of the two identified compatible projectors: the Optoma ZK1320 or ZK1120. The short-throw design is intended to place the projector near the screen while producing the required image. Installers can then use the available zoom, focus, and lens-shift positions to establish the optical setup. Once the desired positions have been reached, full lens memory can save them for later recall.

The available product information does not provide a numerical throw ratio, lens-shift range, physical dimensions, or weight. Those values should therefore not be assumed when planning clearances or mounting geometry. Projector compatibility should likewise be based on the two models explicitly identified by Optoma.

Performance Highlights

The principal stated performance range is image size: the BX-CTA10 can produce images from 50 inches up to 500 inches. Its 1.3x wide zoom adds optical setup flexibility within the installation, and the short-throw format addresses layouts requiring a limited projector-to-screen distance.

Full lens memory extends beyond zoom alone. It saves and quickly recalls zoom, focus, and lens-shift positions, keeping the core optical settings together. This provides a direct way to return the lens to a saved configuration without independently re-establishing each listed position.

What Makes It Different

The defining feature of the BX-CTA10 is the combination of short-throw optics and full memory for three lens functions. A short-distance installation can still benefit from 1.3x zoom adjustment, while the saved zoom, focus, and lens-shift positions support repeatable optical setup. The unusually wide stated image-size span, from 50 to 500 inches, further distinguishes its intended installation scope.

Its application is focused rather than universal. This is a dedicated lens for the Optoma ZK1320 and ZK1120 projector platform, giving prospective buyers a specific compatibility reference instead of an unspecified projector-lens pairing.

Final Assessment

For an immersive installation based on an Optoma ZK1320 or ZK1120 4K UHD+ projector, the BX-CTA10 offers a defined set of useful optical capabilities. It supports short-distance placement, 1.3x wide zoom adjustment, images measuring 50 to 500 inches, and full memory for zoom, focus, and lens-shift positions. Its strongest fit is a compatible system that needs short-throw projection together with fast recall of a saved lens configuration.
