3.5X High-Definition Telephoto Attachment for Sony Alpha 9 — For Lenses with 49, 52, 55, 58, 62 & 67mm Filter Threads

This 3.5X High-Definition telephoto attachment converts your existing DSLR lens into a higher-magnification optic by mounting on top of the lens. Designed for Sony Alpha 9 users, the unit delivers substantial subject magnification while maintaining image quality. Optical construction includes three extra-low dispersion glass elements to control both longitudinal and lateral chromatic aberration in focused and out-of-focus areas, helping to reduce purple fringing and ghosting across the aperture range and cutting down on post-processing time. The attachment features multi-coated optical glass that accepts 72mm filters for improved light transmission and reduced internal reflections, and its shorter flange distance is engineered to enhance sharpness while keeping the accessory compact and more portable than many alternatives. Weighing only 6.4 oz without the hood and standing approximately 2 inches tall, it’s easy to carry for wildlife, sports, portrait, or travel photography. What’s included: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
