The camera features the 18.3mm (28mm in 35mm equivalent focal length) F2.8 GR lens. While inheriting the established design philosophy and incorporating successive advances in optical technology, the lens employs a 5-group 7-element construction, with a large, aspherical high-precision molded glass lens added as the final lens. To fully realize the performance of this lens, the imaging system has been optimized specifically for the monochrome-dedicated GR. The monochrome-dedicated image sensor is not equipped with a color filter and performs no interpolation processing, enabling the GR lens’s outstanding optical performance to be captured in its entirety. The result is exceptional resolution extending to the edges of the frame, rich gradation, and low distortion. The true potential of the GR lens is fully revealed in monochrome.
