It was designed for slide projectors rather than cameras, but photographers adapt lenses like this to modern mirrorless and DSLR bodies for their swirly bokeh and classic vintage rendering. It is a fun project lens for anyone who experiments with old glass.\u003c\/p\u003e\u003ch2\u003eItem Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Projection lens (portrait use when adapted)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Triplet 2.8\/78 (Триплет)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFocal Length:\u003c\/strong\u003e 78 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Aperture:\u003c\/strong\u003e f\/2.8, fixed (no internal iris)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical Design:\u003c\/strong\u003e 3 elements in 3 groups (classic triplet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFocus:\u003c\/strong\u003e No built-in helicoid; manual focus only when adapted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody:\u003c\/strong\u003e Solid metal barrel, black finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 225 g (about 7.9 oz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USSR\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCondition\u003c\/h2\u003e\u003cp\u003eUsed. The glass appears clear for its age. There may be minor internal dust particles or faint cleaning marks typical of vintage lenses, which should not affect the image. The black metal barrel shows some use and minor wear on the finish.

Because it is a projection lens, it has no focusing helicoid and no aperture blades, so using it on a camera needs a specialized adapter or a DIY focusing helicoid, usually based on M42 or M65 systems. Creative photographers who like the soft, swirling background blur of old Soviet glass often look for lenses like this one.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eOne Triplet 2.8\/78 lens, as shown in the photos\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eShipping\u003c\/h2\u003e\u003cp\u003eCarefully packed and shipped worldwide from Ukraine with a tracking number.
