3.5X High-Definition Telephoto Attachment for Sony Alpha DSLR-A330 — Fits 49, 52, 55, 58, 62 & 67mm Filter Threads

This 3.5X High-Definition telephoto attachment mounts over your existing lens to deliver increased magnification for DSLR cameras, including the Sony Alpha DSLR-A330 (compatible only with lenses having 49, 52, 55, 58, 62 & 67mm filter threads). It contains three extra-low dispersion glass elements that control both longitudinal and lateral chromatic aberration in focused and out-of-focus areas, greatly reducing purple fringing and ghosting across the aperture range. The unit’s shorter flange distance is engineered for improved image sharpness and a more compact form factor than many comparable telephoto options, making it ideal for wildlife, sports, and portrait photography. Multi-coated optical glass allows use of 72mm filters while maximizing light transmission and minimizing reflections, and the filter-mount design makes attaching accessories quick and easy. Despite its power, the lens attachment is super compact and lightweight — just 2 inches tall and 6.4 oz without the hood. Package includes: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
