 is the worldwide probably best known lens of TOMIOKA OPTICAL CO., LTD^®. It was designed and produced originally for the company YASHICA^® . The silver aperturte ring seeming noble serves as a special distinguishing feature. The broad checkered focussing ring has been manufactured from black lacquered aluminium. The exceptionally high-quality and solid processing of the mechanical components conveys the feeling to the photographer to have any time a reliable "piece of glass" at his disposal. 

The maximum aperture of F=1.2 is stressed by red characters. Characters and signs of the barrel have yellowly/orange-white held and the markings for the silver diaphragm ring have been attached with black colour. 

The characteristic switch for the M42 screw mount system between a manual and automatic diaphragm mode is available by default. Therefore an adaption to modern [digital-] single reflex cameras is without problems possibly . The system of lens elements shows yellow-white surface reflections. The computation of the courses of light-rays is identically to the CHINON^®-, COSINON^®-, REVUENON^®- und TOMINON^®- TOMIOKA^®-lenses from the common DX-series. The important characteristic feature, besides the hallmark of the manufacturer on the front plate, of all 55mm F=1.2 M42-TOMIOKA^®-lenses, is the cut large back-lens fitted in into the fodder of the screw mount. This indicates the Auto YASHINON^®-lens as a TOMIOKA !! 

There are no special multicoated lenses of this variant, since such layers were used only for the successor the YASHINON^® DS-M TOMIOKA^®. 

The manufacturer key for YASHICA^® is "552". The produced quantity is enclosed up to 9,000 copies worldwide. In the direct comparison with the production numbers for the 55mm F=1.2-M42-Tomioka-lenses of other brand names this is a very high value, because the sales radius extended over the markets of America, Europe and Asia. Due to the direct origin from YASHICA^®-product family, however, a great quota of collector's items consists in showcases just at this type of lens. Until approx.. 

Perhaps everyone of this TOMIOKA^®-lenses should have changed its owner ... ? 

The Auto YASHINON^® has the lowest mass weight of all 55 mm F=1.2 M42 screw mount-lenses of the company TOMIOKA OPTICAL CO.,LTD^® of "only" approx. 335.77 grams, as an exercised athlete.
