ET-D3LEW201 — Short-Throw Zoom Lens with Zero Offset
Think of this one as the ET-D3LEW200's slightly more flexible sibling, same short-throw performance for tight rooms, but with a wider WUXGA throw ratio on the RQ25K Series (0.779–1.02:1 versus 0.645–0.85:1 elsewhere), giving you a bit more room to work with when the projector body is one of the RQ25K family. Everything else that makes this lens family good stays the same: zero-offset alignment, powered zoom and lens-shift so nobody's climbing a ladder for adjustments, and that L-shaped build that keeps the audience's view clear even in low-ceiling rooms.
Key Features:
- Throw ratio 0.645–0.85:1 (WUXGA, most compatible bodies) / 0.779–1.02:1 (WUXGA on RQ25K Series)
- Zero-offset design for clean image alignment, no wasted margin above or below
- Powered vertical and horizontal lens-shift for adjustment after installation
- Powered optical zoom for extra flexibility once mounted
- L-shaped design keeps sightlines clear even in low-ceiling installs
- Supports AFO (Active Focus Optimizer) to hold focus regardless of content brightness
- On select projectors with a firmware update, the lens continuously monitors ambient temperature to keep focus sharp even right after start-up
