3.5X High-Definition Telephoto Converter for Sony SLT-A77 (For Lenses with 49, 52, 55, 58, 62 & 67mm Filter Threads)

Compact 3.5x telephoto converter designed for DSLR use and specifically compatible with the Sony SLT-A77. This unit mounts in front of your existing lens to increase apparent focal length while maintaining image quality. Optical construction includes three extra-low dispersion glass elements to suppress both longitudinal and lateral chromatic aberration in in-focus and out-of-focus regions, and it minimizes purple fringing and ghosting across the aperture range to reduce post-processing time. The converter’s shorter flange distance improves image sharpness and allows a smaller, more portable form factor compared with similar add-on telephoto options. Multi-coated optical glass and a front that accepts 72mm filters ensure high light transmission and reduced internal reflections; filter attachment and use are straightforward thanks to the user-friendly design. Ideal for wildlife, sports, and portrait photography, this converter delivers enhanced detail and clarity without adding bulk. Physical specs: 2 inches in height and 6.4 oz weight (without hood). Item Includes: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
