Model 287, a wide-angle lens adapter from Resolve Optics Ltd., is designed to double the field of view (FOV) throughout the zoom range of any zoom camera. It provides a true 0.5x FOV while maintaining minimal distortion and high resolution. The compromise-free performance is the result of designing the adapter to work with the moving pupils of zoom lenses. The design, which incorporates specialized high-index glasses, balances a low-distortion, wide-angle view with the higher level of correction needed at narrow angles. The result is a high-quality lens that has full zoom-through capability and that produces high-contrast images, regardless of zoom position, while maintaining resolution and focus to the very edges of the image.
