Awesome set of Leica lenses and filters in their original boxes, made in Germany circa 1940. This complete accessory set is entirely original from the time and remains in very good condition. It includes three magnifying lenses for macro photography and two yellow filters of different intensity: Nº 1 and Nº 2. The lenses are also marked with their corresponding numbers: 1, 2 and 3. The set also contains a 5 3.5 cm adapter designed to mount the lenses and the filters in 5 and 3.5 cm objectives. All the items (except the adapter) come in their original boxes, made of red-fabric-covered cardboard boxes and with the manufacturers name (Ernst Leitz Wetzlar) embossed in golden lettering together with the description of the content in German. The boxes are finely preserved and show very slight signs of wear, with complete and clearly legible inscriptions. This set of Leica lenses and filters in their original boxes is an exclusive item which any photo lover who has an old-time Leica camera will long to own.Ernst Leitz Wetzlar History The beginnings of the famous optic material manufacturing company named Ernst Leitz Wetzlar can be found in the first half of the 19th century, when the mechanic and selft-taught mathematician Carl Kellner founded the Carl Kellner Optisches Institut in Wetlzar, Germany. After his early death his widow maintained the business, and in 1864 the mechanical engineer Ernst Leitz entered the company. Just five years later, Leitz took control of the firm and changed its name for Ernst Leitz Wetzlar. Leitz led the company to success after introducing improvements such as serial production, raising sales volume rapidly after 1871. Leitz microscopes included technical improvements that increased their quality; by the late 19th century the company already had a worldwide reputation. Ernst Leitz died in 1920 and the leadership of the firm passed to his son. As well as for their microscopes and optic material, Leitz became hugely famous for their famous Leica cameras (abbreviation of Leitz Camera).
