3.5X High-Definition Telephoto Lens for Nikon 1 J4 — Only for Lenses with 49, 52, 55, 58, 62 & 67mm Filter Threads

Compact 3.5x telephoto attachment engineered for DSLR use and compatible with the Nikon 1 J4. This front-mounted telephoto optic screws onto your existing lens (only for lenses with 49, 52, 55, 58, 62 & 67mm filter threads) and increases subject magnification without degrading image quality. Optical design includes three extra-low dispersion glass elements that suppress both longitudinal and lateral chromatic aberration in focused and defocused areas, and the coating minimises purple fringing and ghosting across the aperture range. The unit’s shorter flange distance improves sharpness while keeping the assembly small and portable compared with similar adapters. The telephoto is built from multi-coated optical glass and accepts 72mm filters on its front; included stepping rings allow attachment to the specified smaller thread sizes. Physical specs: approximately 2 inches in height and 6.4 oz in weight (without hood). Ideal for wildlife, sports and portrait work. Package contents: Lens, Pouch, Stepping Rings, Lens cap, Bottom Cover.
