<b>GR lens for high-quality image reproduction</b><br>Developed in pursuit of pure image quality, the GR 18.3mm F2.8 lens (equivalent to 28mm in the 35mm format) delivers simply the best performance in GR’s history. This acclaimed lens design incorporates two high-precision glass mold aspherical optical elements and a high-refraction, lower-dispersion glass element, positioned optimally to reduce distortions and chromatic aberration to near absolute minimum, while reproducing high-resolution images from the center to the edges of the image field. Thanks to its crisp image rendition even at the maximum aperture of F2.8, and its faithful image reproduction against backlight, the user can truly enjoy the charm of a unifocal lens.

Its nine-blade iris diaphragm helps create a truthful sense of depth and a natural bokeh (defocusing) effect, while allowing the user to capture beautiful light beams at closed-down apertures.<br><br><b>Large CMOS image sensor captures the finest details</b><br>T This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 4720-00-067-0454, indicating validated use in U.S. government and defense logistics supply chains.
