Designed for quick, intuitive use, it emphasizes speed, accuracy, and creative flexibility, turning ordinary presentations into engaging visual experiences. Whether you’re outfitting a classroom, conference room, or home theater, this telephoto zoom lens provides crisp detail, ease of installation, and the performance you expect from BenQ’s projection technology.

• Focal range and zoom versatility: The 32.90 mm to 54.20 mm focal span delivers a flexible 1.7x optical zoom, allowing you to frame content precisely from varying distances without moving the projector. This range supports everything from expansive slides and group demonstrations to focused speaker shots, giving you dynamic control over image composition in real time. The ability to switch from wide to tight framing quickly is especially valuable in classrooms, meetings, and event spaces where seating configurations change frequently.

• Bright, compelling projection: A bright maximum aperture of f/2.48 ensures robust light transmission, producing clearer, more legible images even in medium-lit environments. This helps preserve text readability in presentations, maintain vivid color in multimedia content, and reduce the need for high-output projectors in smaller rooms. The combination of brightness and efficient optical design translates to punchy visuals with strong contrast, making diagrams, charts, and visuals stand out with minimal post-processing.

• Sharpness and color fidelity: Engineered for superior image quality, this telephoto zoom lens emphasizes edge-to-edge sharpness and accurate color reproduction across the frame. By minimizing common telephoto aberrations, it delivers crisp details—from tiny font sizes in technical diagrams to fine textures in high-resolution images. The result is projection that remains faithful to the source material, whether you’re teaching complex concepts or showcasing high-definition media.

• Compact, portable design: The lens is built with portability in mind, offering a compact, lightweight silhouette that fits neatly into a projection toolkit. Its streamlined construction makes mounting and transport straightforward, enabling quick room-to-room setup and minimal downtime between venues. This design philosophy aligns with modern education and business environments where space is at a premium and ease of use matters just as much as performance.

• Creative projection capabilities: The 32.90–54.20 mm focal range invites creative framing opportunities, from telephoto compression that brings distant subjects visually closer to dramatic close-ups of content at the screen. This flexibility supports a range of projection styles—lectures, product demos, and live events—allowing presenters to tell a clearer, more compelling visual story without sacrificing image quality or brightness.
