In 1959, Lester Bogen, an accomplished photographer and writer bought a small photographic import and distribution company that supplied darkroom and small camera accessories. This was the start of Bogen Imaging Inc. that today supplies the photographic, video, Cine and lighting markets with an extensive range of leading product lines.
In 1970, Lester met Lino Manfrotto, who manufactured lighting stands and accessories in northern Italy. Manfrotto appointed Bogen the exclusive U.S. distributor and their partnership produced the world famous range of camera tripods, heads, lighting stands and accessories. Manfrotto sets the international standard for top quality professional equipment and is a superb value for the money. The line was marketed under the Bogen brand name up until 1998 and now uses the international name "Manfrotto".
In 1993, Bogen was acquired by the Vitec Group, a company listed on the London stock exchange. Today Bogen is an integral part of the Vitec Photographic Division, which includes Gruppo Manfrotto and Gitzo.
The Bogen line has come to include many of the most respected manufacturers of precision products under the "Exclusively Bogen" logo; Gitzo tripods and heads, Avenger lighting grip, I.F.F. ceiling mounted lighting suspension, Metz on-camera flash systems, Gossen light meters, Elinchrom studio lighting systems and a wide host of additional product lines which round out the most complete range of exceptional accessories in the business.
Bogen's status as a true powerhouse in the industry is evident by the depth and breadth of their organization and the markets they serve. Bogen sells to retailers in the photography and video markets in addition to rental houses in the film and broadcast industry. This national network of over 2000 dealers attest to their solid reputation for quality products and prompt, professional service.
