ET-C1S600 — Zoom Lens (Supplied Lens)

This is the standard-throw lens supplied with the PT-REQ15 and PT-REZ15, a 1.36–2.10:1 (WUXGA) throw ratio zoom for typical installation distances — roughly one and a half to two times the image width. It's the baseline lens in the C1 family: no powered peripheral focus, but the same UED glass benefits and full compatibility across the REQ15/REZ15 series lineup.

Key Features:

• Standard throw ratio of 1.36–2.10:1 (WUXGA) — supplied as-standard with PT-REQ15 and PT-REZ15
• Also usable as an optional lens on PT-REQ12/REQ10/REQ80 and PT-REZ12/REZ10/REZ80
• UED glass for improved native contrast and color uniformity over equivalent DLE Series lenses
• Auto Lens Identification and Lens Memory supported for rapid switching between projection setups
• Note: does not support powered peripheral focus (like the T700/T800 lenses)
