Agfa/Reflecta Slide Projector Models With one exception, Agfa slide projector lenses were not serialled – often an indicator that the manufacturer doesn’t take them seriously. Agfa’s reputation in Mainland Europe is healthy, but UK opinion is well summarised by the view of a repair specialist who recently harrumphed in my direction: “Well… Agfa projectors – …
Colour and Collaboration The Agfa story begins in 1867 in Rummelsburger See, on the outskirts of Berlin, when chemists Paul Mendelssohn Bartoldy and Carl Alexander von Martius founded the Gesellschaft Für Anilin-Fabrikation mbH. For the next 120 years, this expertise cast the die for Agfa’s successes and failures: aniline is a base ingredient in dyes, …
The family tree planted by Bausch & Lomb in 1874?, that bifurcated and recombined across over a century of American optics production, has been well documented elsewhere (notably Rudolf Kingslake and Dan Fromm, but it is worth preçis here, with added information relevant to the identification and dating of enlarger, projector and industrial lenses. However, …
If Agfa somewhat receded from the minds of consumers in the second half of the Twentieth Century, the company’s involvement in what we might call ‘industrial’ optics certainly did not – encompassing photo-industrial devices such as minilabs and printer controllers, and the full spectrum of imaging applications for medical and manufacturing industries. If Agfa’s ‘over the …
Frequently, confusion. As if we didn’t have enough trouble cataloguing lenses with names like Bender, Nooky and Veginar, (thanks Lumaplak, Leica and Boots), Delta-world is far from the semantic ideal of one name for one thing. Major changes to a lens design sometimes go unflagged, while other, outwardly dissimilar lenses are optically identical. In many …

Everyone and their aunt made a 50mm enlarger lens. And if you use a 50mm enlarger lens, you have to ask: why not use one of the hundreds – nay, thousands – of standard 50mm taking lenses, which everyone’s aunt and uncle made too? Adding to the excitement, we even find the odd wide angle …
Almost a century and a half of optical engineering: from taking lenses to sunglasses; from Rodenstock to Linos to Qioptiq to Excelitas. Rodenstock lenses and lens cells can be dated as follows: 50 000 1910 200 000 1920 400 000 1930 700 000 1935 900 000 1938 950 000 1940 2 000 000 1945 2 …
Based in Görlitz, a designation that often appears on their lenses, the “Optisch-Mechanische Industrie-Anstalt Hugo Meyer & Co.” was founded in 1896 by the optician Hugo Meyer and the merchant Heinrich Schätze. The maker, in co-operation with Paul Rudolph, was an early pioneer (from 1918) of Plasmat lens manufacture, and rapidly expanded between 1920-1942, largely …
