Pentax introduced this in 1979, at a time when electronic exposure controls could be miniaturised to the point where they could be used in a device this small. And it&#8217;s really, really, small!<\/p>\n\n\n\n<p><strong>Technical Details<\/strong><\/p>\n\n\n\n<p>This is the only interchangeable lens SLR ever produced for the 110 film cartridge &#8211; there were fixed lens 110 cameras from other manufacturers. It offers program only TTL auto exposure, and a range of 6 lenses in the Pentax 110 Bayonet format:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>18&nbsp;mm f\/2.8&nbsp;wide-angle lens&nbsp;(equivalent angle of view to a 35&nbsp;mm lens on a&nbsp;135 format&nbsp;camera).<\/li>\n\n\n\n<li>24&nbsp;mm f\/2.8&nbsp;normal lens&nbsp;(equiv. 50&nbsp;mm). The optical design meant that this was the smallest lens on the system.<\/li>\n\n\n\n<li>50&nbsp;mm f\/2.8&nbsp;telephoto lens&nbsp;(equiv. 100&nbsp;mm)<\/li>\n<\/ul>\n\n\n\n<p>In 1981, three more lenses were included:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>18&nbsp;mm &#8220;Pan Focus&#8221; lens was a compact lens of fixed focus set to the&nbsp;hyperfocal distance; the short focal length and wide aperture meant that its depth of field stretched from 1.75&nbsp;m (5.7&nbsp;ft) to infinity. The camera aperture needed to be set at f\/6.3 for this lens to work as intended.<\/li>\n\n\n\n<li>70&nbsp;mm f\/2.8 telephoto lens (equiv. 140&nbsp;mm)<\/li>\n\n\n\n<li>20\u201340&nbsp;mm f\/2.8 zoom lens (equiv. 40\u201380&nbsp;mm). This lens extended for wider focal lengths and shortened towards the telephoto end.<\/li>\n<\/ul>\n\n\n\n<p><strong>The Museum Sample<\/strong><\/p>\n\n\n\n<p>Found, as usual, on eBay complete with flash, filters, case, and all the original manuals for $90. It&#8217;s generally quite clean, but the 110 film is tough to find and so difficult to tell if it still works.<\/p>\n\n\n\n<p>The flashgun, tiny as it is, still dwarfs the camera itself.<\/p>\n\n\n\n<div class=\"wp-block-jetpack-slideshow aligncenter\" data-autoplay=\"true\" data-delay=\"3\" data-effect=\"slide\"><div class=\"wp-block-jetpack-slideshow_container
