3.5X High-Definition Telephoto Converter for Sony SLT-A37 (For 49, 52, 55, 58, 62 & 67mm Filter Threads)

This 3.5x high-definition telephoto converter is made for DSLR use and specifically compatible with the Sony SLT-A37. It mounts on top of your existing lens to deliver a 3.5× magnification, turning your current setup into a longer-reach telephoto without sacrificing image quality. Optical performance is enhanced by three extra-low dispersion glass elements that control both longitudinal and lateral chromatic aberration in in-focus and out-of-focus areas. The design also reduces purple fringing and ghosting across the aperture range, cutting down the need for corrective post-processing. Built with a shorter flange distance for DSLR cameras, the converter improves image sharpness while remaining more compact and portable than many comparable solutions. Multi-coated optical glass ensures high light transmission and lower reflections, and the front accepts 72mm filters for creative control. Stepping rings are included to adapt to lens filter threads. Lightweight and travel-friendly, the unit measures approximately 2 inches in height and weighs 6.4 oz (without the hood), making it easy to carry on shoots for wildlife, sports, or portrait work. Item includes: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
