The Sanyo ET-ELT21 LNS-T21 Christie 103-128102-XX Ultra Throw Projector Zoom Lens is a specialized lens designed for use with certain Sanyo projectors, specifically those in the ET-Series, to provide an ultra-short throw projection experience. This lens offers several advantages and disadvantages that potential buyers should consider before making a purchasing decision:
Advantages:1. Ultra-short throw length: This lens provides an incredibly short projection throw distance, making it an excellent choice for projecting large images in tight spaces without requiring significant distance between the projector and the screen or wall.
2. High resolution and brightness: With a native resolution of 1280x800 and a reported brightness of 4000 ANSI Lumens, the lens yields sharp and detailed images even in relatively well-lit rooms, making it suitable for various applications, such as offices, classrooms, and meeting rooms.
3. Wide zoom range: The lens provides an impressive zoom range (1.1x to 3.27x) that allows users to cover large spaces without having to move the projector. This feature saves time and effort, especially for projects that require frequent size adjustments or involving multiple display surfaces.
4. Lens shift capability: The lens features a /- 15% lens shift capability, which helps overcome room geometry issues, such as ceilings or floors not being level, without sacrificing image quality or struggling with keystone correction.
Disadvantages:1. Expensive: The Sanyo ET-ELT21 LNS-T21 Christie 103-128102-XX Ultra Throw Projector Zoom Lens is relatively expensive. Depending on availability, the pricing may be higher than comparable lenses on the market, making it a significant investment, especially for non-commercial and home use.
2. Limited compatibility: This lens is designed exclusively for use with select Sanyo projectors, making it essential to ensure compatibility before purchasing. It will not work with other projector brands.
3. Size and weight: The lens is quite large and heavy, which may complicate storage, transport, and installation particularly for those who require frequent relocation of their projector setups or do not have sufficient space for the additional equipment.
4. Potential image degradation: When using ultra-short throw projectors, the image may appear slightly distorted, the brightness can be uneven, and there may be some visible decrease in contrast and color reproduction. This effect is most noticeable when using the lens at the maximum zoom range, and these potential issues should be considered before making a final decision.
Conclusion:The Sanyo ET-ELT21 LNS-T21 Christie 103-128102-XX Ultra Throw Projector Zoom Lens offers a convenient, high-resolution, and bright projection solution for users requiring short throw distances with an extensive zoom range and lens shift capability. However, its high price point, limited compatibility, and significant size and weight may deter some buyers. Carefully consider your personal needs, budget, and available space before deciding to invest in this lens. For users that frequently shift projector locations and have a smaller budget, other, more versatile lenses on the market may be a better fit. Nonetheless, for those in need of a specialized ultra-short throw lens for their Sanyo projector, this lens could prove to be a valuable addition.
