Standard grades of optical glass offer good image quality in ideal lighting conditions. For the best performance in low light situations, it is necessary to consider high grades of glass.
High-grade glass types, such as ED, FL, and HD, offer noticeably enhanced resolution and color fidelity.
The increased image quality from high-grade glass is especially obvious when viewing in low light.
