After extensive research and development, Sony presents the Fe 100-400mm f/4.5-5.6 Gm Oss Lens, a flagship product in the G Master series. This high-quality, super-telephoto zoom lens offers a versatile focal length range, perfect for capturing sports, wildlife, and other distant subjects with extraordinary resolution and immediacy. The lens boasts an advanced optical design, featuring two Ed (Extra-low Dispersion) glass elements and one Super Ed glass element. These elements effectively suppress axial chromatic aberration, often a cause of resolution falloff in telephoto lenses, resulting in clear, well-defined images. Sony's innovative Nano Ar Coating enhances clarity and contrast by suppressing reflections that can cause flare and ghosting in challenging lighting situations. This feature ensures consistently high contrast and clarity, providing greater framing and composing flexibility, especially in bright outdoor conditions.
