FAQ — Zorsika BU70QGA Frequently Asked Questions
Q: What does the throw ratio of the Zorsika BU70QGA lens mean?
A: Throw ratio = projection distance / image width. The smaller the ratio, the larger the image at the same distance. The Zorsika BU70QGA has a throw ratio of , making it a medium throw lens. It is recommended to inversely calculate the achievable screen size based on the installation distance, or consult Zorsika sales for selection calculation assistance.
Q: Which projector models are compatible with the Zorsika BU70QGA lens?
A: The Zorsika BU70QGA lens is compatible with 1 LG projector model. Please refer to the "Compatible Projector Models" table in this article. To confirm whether a specific model is compatible, contact Zorsika sales and provide a photo of the projector nameplate. We will verify lens and body compatibility for you.
Q: What does the lens MTF (Modulation Transfer Function) represent?
A: MTF (Modulation Transfer Function) reflects the lens's ability to reproduce detail. The higher the value, the sharper the image. Professional projector lenses typically require MTF > 50% @93lp/mm. The MTF index of the Zorsika BU70QGA lens is -. In 4K projection applications, MTF is a core indicator for determining whether the lens truly supports 4K resolution.
Q: What size of meeting room is the Zorsika BU70QGA medium throw lens suitable for?
A: The Zorsika BU70QGA has a throw ratio of , making it suitable for small to medium-sized meeting rooms with a depth of 3–6 meters. It is recommended to install the projector at a distance of 3–4 meters, achieving a 100–150 inch image. If the room depth exceeds 6 meters, consider using a long throw lens instead.
