Projection lens Epson ELPLX01S — fixed focal length 5.8 mm, fixed aperture 1.9 mm, compatible with select Epson projectors

The Epson ELPLX01S is a fixed focal length projection lens with a 5.8 mm focal length and a fixed f/1.9 aperture, designed for use with select Epson projectors. Finished in black and built with a robust construction, this lens aims to deliver clear, stable images for professional presentations, events and permanent installations. Weighing approximately 3.49 kg, it is intended for applications where a reliable, high-performance projection lens is required.

Advantages

The fixed 5.8 mm focal length provides a consistent field of view and simplified setup when the installation geometry matches the lens throw. A fixed f/1.9 aperture helps maintain brightness and image clarity in environments that require a higher light transmission. The lens’s solid build and black finish reduce stray reflections and support long-term use in fixed installations or touring setups where durability is important.

Suitable for

• Professional conference and meeting rooms with compatible Epson projectors
• Event venues and auditoriums requiring stable, repeatable projection geometry
• Permanent AV installations such as museums, retail displays and signage
• Rental and touring setups where robust lens construction is required

When it may not be suitable

This lens has a fixed focal length and fixed aperture, so it is not suitable when variable zoom or adjustable aperture is required for flexible throw distances or depth-of-field control. It is intended only for use with compatible Epson projector models; use with unsupported projector platforms may result in suboptimal fit or performance. The relatively heavy weight should be considered for lightweight or delicate mounting structures.

Key specifications

• Focal length: 5.8 mm (fixed)
• Aperture: f/1.9 (fixed)
• Finish: black
• Construction: durable housing suitable for installations
• Approximate weight: 3.49 kg

How to use

Install the lens according to the projector manufacturer’s instructions, ensuring the projector is powered off and secured before attaching the lens. Align the lens to the projector’s lens mount and lock it into place following the projector’s mounting procedure. After physical installation, power on the projector and use the projector’s built-in focus and keystone adjustment features, if available, to fine-tune image sharpness and geometry. For fixed installations, perform a final alignment and secure any lens locks or safety fastenings to prevent movement.

What to consider before purchase

• Confirm compatibility with your specific Epson projector model
• Ensure the installation throw distance and screen size match the fixed 5.8 mm focal length
• Check mounting support and weight capacity for a ~3.49 kg lens
• Decide if a fixed aperture and fixed focal length meet your flexibility needs

Recommendations

For best results, use the lens in a controlled installation where throw distance and screen size are predetermined. Verify projector compatibility before installation and perform alignment and calibration in the actual viewing environment to achieve optimal image clarity and geometry.
