Raynox HDP-2805 ES High Definition Diagonal Fisheye Converter 0.28x. The HDP-2805ES is a fisheye converter that allows ultra-wide-angle shots when used with high-definition digital camcorders and cameras. The converter is designed to focus across the entire zoom range when used with 5x zoom lenses. It is made from optical eco-glass with 3 groups/3 elements and is characterized by its exceptional compactness and lightweight design. It achieves a high resolution of 475 line pairs per millimeter at the center of the image (MTF 30%). When used in front of a wide-angle lens with a focal length of 26 mm or less (equivalent to 35 mm full-frame), the converter enables 180° diagonal shots. The package includes two adapter rings with thread sizes of 52 to 49 mm and 52 to 52 mm, allowing the converter to be screwed onto lenses with these filter thread sizes. - 52 mm thread size - Consistently true HD quality - Produces an image with a distortion of -64%, creating the fisheye effect - 3 groups / 3 elements high-definition design - Compact and only 205 g in weight. For some camera lenses, peripheral resolution is improved by first attaching the 52 to 52 mm adapter ring to the 0.28x converter and then mounting the corresponding adapter ring on top.
