The Panasonic ET-D3LET40 is a long-throw zoom lens designed for use with Panasonic’s 3-Chip DLP™ projectors, particularly in large venues where extended projection distances are required.
This lens is ideal when you need maximum throw distance without compromising image clarity or motorized control.
The ET-D3LET40 is a long-throw zoom lens specifically engineered for Panasonic’s 3-Chip DLP™ projector systems. This lens is designed to offer flexible installation options, especially in large venues like auditoriums, lecture halls, and outdoor events where extended throw distances are necessary. It delivers motorized zoom, focus, and lens shift, enabling fine-tuned adjustment without manual recalibration—ideal for high-end professional environments that demand precision and minimal setup disruption.
Its throw ratio ranges vary depending on the projector model, offering values such as 4.94–7.94:1 on PT-RQ32K and RQ22K (for 16:10 aspect ratios), or up to 8.02:1 on RS30K models with 4:3 aspect ratios. This adaptability makes the lens particularly suited for configurations where the projector cannot be positioned close to the screen. The focal length spans from 96.6 mm to 154.9 mm, with an aperture of f/2.5 that allows sufficient light transmission even over long distances.
A standout feature is its built-in lens memory and auto lens identification, streamlining installation and facilitating seamless projector swaps or configuration changes. Compatible projector models include PT-RQ32K, PT-RZ31K, PT-RS30K, PT-RQ22K, PT-RZ21K, and PT-RS20K. With a robust construction weighing around 5.0 kg, the ET-D3LET40 balances durability with smooth motorized control, marking it as a reliable solution for professional AV deployments requiring high-performance optics and exacting standards.
