Useful controls such as a printed distance and magnification scale on top, a focus range limiter, and a focus hold button allow for more precise focusing for better results. In addition to the handling options, the optical design includes both an aspherical element and an extra-low dispersion element, which suppress chromatic and spherical aberrations, thereby enhancing clarity across the entire focus range. Furthermore, the lens is designed to be dust and moisture resistant, making it easier to work in unfavorable weather conditions.
