Half-size format 25mm F3.5 fixed-focus lens Bright optical viewfinder Film advance lever Half-size format for capturing a large number of pictures The PENTAX 17 is a half-size-format camera that employs a left-to-right film advance mechanism. When positioned in the normal way, it captures vertical-format pictures, identical to the familiar images captured by smartphones. Film advance lever with a nostalgic film camera look The PENTAX 17 uses a manual film-winding mechanism featuring a film advance lever, to recreate the feel of a traditional film camera. To improve the feel of the film-winding action after each shutter release, this lever is designed for optimal finger hold. Fixed-focus lens to optimize image quality The PENTAX 17 features a 25mm F3.5 fixed-focus lens (equivalent to a 37mm lens in the 35mm format). This lens is treated with HD (High Definition) coating — highly acclaimed through its application on PENTAX SLR lenses — to optimize the image quality of half-size pictures. As the result, the PENTAX 17 delivers sharp, clear images. Bright optical viewfinder to assure sharp subject image The PENTAX 17’s optical viewfinder features an Albada-type bright frame finder. It also comes with a close-up visual field compensation frame to help you more easily compose close-up images. It is possible to check the zone marks directly through the viewfinder.
