With the GR IIIx, a long-standing wish of many photographers is now fulfilled. The chassis and user interface of the GR III remain unchanged, and instead of the previous 28 mm focal length (equivalent to full frame), the new lens offers a focal length of 26.1 mm, which corresponds to 40 mm in full-frame format, making it nearly a standard lens. This focal length is legendary not only in the PENTAX system but is also considered a perfect compromise for classic documentary photography. It provides a natural viewing perspective and allows for greater distance from the subject than before, enabling a pronounced separation of the subject with significant depth effect.
