BelOMO plant INDUSTAR-69 28mm F2.8 M39 LENS for CHAIKA CAMERAS ABOUT ITEM'S ORIGIN (You can SKIP it!) The Chaika cameras was produced in 1965-1973 years at Belorusskiy Optical and Mechanical Factory (BeLOMO). "Chaika" was space ID of Valentina Tereshkova, the first woman in the World who made the space voyage. Chaika cameras were point-&-shoot cameras, but it had been equipped by removable Industar-69 lens. ITEM'S CONDITION: WELL-USABLE The glass is enough clean and should bring nice images, without scratches, separations or fungus, but some cleaning marks at optics and some pieces of dust inside can be found. Aperture blades open and close smoothly, focusing is smooth too. Cosmetically the lens looks nice (just examine item's photos, please). All functions are available. You can see example photos taken with presented lens at F2.8 & F8. I took it with my Olympus OM-D camera. TECHNICAL FEATURES * Focus: 28 mm. * Frame size 18x24mm. * Angle of view: about 45 degrees for 18x24mm frame size. It will make vignetting at usual 24x36mm frame size. * Relative aperture: 1:2.8. * Aperture: from 2.8 up to 16 (without f-stop clicks). * Mounting: M39 (LTM) screw mount, but optical registration is other, 27.5mm (1.3mm more short). Thus the lens will not provide "infinity" focusing at genuine 28.8mm LTM registration. Very good idea is to use the lens with mirrorless digital MFT cameras like Sony NEX, Lumix etc. Just add the adapter for it... * Different M39 adapters can be upgraded to use this lens with different MFT digital cameras. * Resolution (pairs of lines per 1 mm): not less than 45 in the center and 20 on the edge of frame. * Dimensions: length 20 mm (at infinity), diameter 47 mm. * Weight: 54 g (lens only). * Filter mount: screw mount 22.5x0.5 mm. * Made in USSR at the city of Minsk at the plant of Vavilova (BeLOMO) in 1960-1970s.
