The PENTAX MX-1 features a 4X optical zoom lens offering a large maximum aperture of F1.8 to F2.5 and 28mm wide-angle coverage (in the 35mm format). When set at maximum aperture and widest angle of view the photographer can use fast shutter speeds in dimly lit locations and take advantage of a beautiful bokeh (out-of-focus) effect in the background. The MX-1 also provides a Macro mode to capture dramatic close-up images of subjects from as little as one centimeter away. Additionally, the Intelligent Zoom (digital zoom) function extends the zoom coverage up to approximately 7.8 times (for a focal length of approximately 218mm (in the 35mm format) without compromising image quality by optimizing the resolution to match the zoom length.
