3.5X High Definition Telephoto Lens Compatible with Canon EOS 30D — Fits Lenses with 49, 52, 55, 58, 62 & 67mm Filter Threads

This 3.5X High-Definition telephoto prime is designed to mount over your existing DSLR lens to extend reach while preserving image quality. Built for use with Canon EOS 30D and similar DSLR bodies, the adapter-style design keeps the overall system compact thanks to a shorter flange distance, improving sharpness without adding bulk. Optical construction includes three extra-low dispersion glass elements to reduce longitudinal and lateral chromatic aberration in both in-focus and out-of-focus areas, helping to eliminate purple fringing and ghosting throughout the aperture range. Multi-coated optical glass ensures high light transmission and reduced reflections; the front accepts 72mm filters for easy use of polarizers or ND filters. Despite its powerful magnification, the unit is lightweight and pocketable — it stands 2 inches tall and weighs 6.4 oz (without the hood). The lens is user-friendly for on-location shooting, and attaching filters is straightforward. Package contents: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
