ApoSymmar
ApoSymmar is a brand name for a series of high-performance photographic lenses manufactured by Schneider-Kreuznach. These lenses are particularly known for their advanced optical designs, often featuring apochromatic correction. This correction minimizes chromatic aberration, a common optical distortion that can lead to color fringing in images, especially at high contrast edges. ApoSymmar lenses are typically designed for large format cameras and are favored by professional photographers for their exceptional sharpness, contrast, and color rendition. The lens elements are often made from specialized glass with anomalous dispersion properties, contributing to their superior performance. They are commonly used in applications where image quality is paramount, such as landscape photography, architectural photography, and portraiture. The ApoSymmar line has evolved over time, with different focal lengths and aperture variations available to suit various photographic needs. Their robust construction and precise manufacturing contribute to their reputation for durability and reliability in demanding professional environments.
