3.5x High-Definition Telephoto Converter for Pentax K-50 — Fits 49, 52, 55, 58, 62 & 67mm Filter Threads

Built for DSLR photographers using the Pentax K-50, this 3.5x High-Definition Telephoto Lens mounts in front of your current lens to boost subject magnification while preserving image quality. Optical construction includes three extra-low dispersion glass elements to suppress longitudinal and lateral chromatic aberration in both in-focus and out-of-focus zones, reducing purple fringing and ghosting across the aperture range so you spend less time editing. A shorter flange distance tailored for DSLR systems improves sharpness and keeps the unit smaller and more portable than many comparable converters. The lens uses multi-coated optical glass and accepts 72mm filters to maximize light transmission and minimize reflections; filters are easy to attach for quick creative control. Exceptionally compact and lightweight, it measures just 2 inches in height and weighs only 6.4 oz without the hood, making it a convenient choice for wildlife, sports, and portrait work. Includes: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
