Lenses were made in the following lens mounts: 28–85mm 1:2.8–3.8 varifocal macro zoom ( aka "The Stovepipe").In June 2011 Illinois-based IDEX Corporation completed its $400 million acquisition of the laser and optical component maker CVI Melles Griot from its previous owner, the private equity firm Norwest Equity Partners. In 1995 the firm has changed its name to 'Melles Griot Ltd', and subsequently became a member of CVI Melles Griot Group in 2007. In 1989 Kino Precision Industries merged with 'Melles Griot Japan' to form 'Kino-Melles Griot'. By 1988, the company decided to discontinue after-market 35mm camera lens production to concentrate on industrial and other markets. Additionally, the 35mm camera market was in flux by the late 1980s, and 35mm camera manufacturers were transitioning to autofocus lens designs. The increasing cost of quality lens manufacture in Japan led to a loss of sales for Kiron, as the company could no longer offer its lenses at a cost less than that charged by the camera manufacturers, who had begun to offer economy-level lens designs as well as contracting lens assembly operations in lower-cost factories outside Japan. They begin with the serial number 22XXXXXX. Later, Vivitar itself would purchase some Kiron/Kino lens designs, (such as the Kiron 105mm f/2.8 macro lens, re-labeled as the Vivitar 100mm f/2.8 macro and the Vivitar 105mm/2.5 (1:1) macro lenses), and offered them for sale under the Vivitar brand. As such, Kiron lenses produced during the 1980s were normally priced only slightly below lenses offered by the camera manufacturers themselves. Īlthough reasonably priced for the level of quality offered, Kiron manual focus lenses were never economy-level products, and were always made and assembled in Japan. In particular, the Kiron 28mm/2.0, the 105mm/2.8 1:1 macro, the 28-210mm/4.0-5.6 and the 3.8-5.6 varifocal zoom, and the 28-85mm/2.8-3.8 varifocal macro zoom lenses were praised in contemporary reviews of the day for their superb optical resolution and clarity, as well as mechanical quality. Kiron soon became known as one of the very few after-market lens manufacturers that could supply products equal to or even exceeding the optical and mechanical quality of the original manufacturer. However, after the positive reception from consumers on Vivitar Series 1 lenses, and as Vivitar was using other Japanese lens manufacturers to produce Vivitar brand lenses, the company believed the time was right to successfully market lenses to fit existing 35mm Japanese film cameras under their own brand, Kiron. lens distributor of after-market film lenses for 35mm cameras. Originally, Kino Precision manufactured some of the now-famous Series 1 manual focus lenses under contract for Vivitar, a U.S. A Kiron-made Vivitar 70-210mm f/3.5 Series 1
