I am always interested in odd lenses, particularly LTM's. So recently I saw a Pam Britar 105mm f/4.5 that looked interesting. However, in spite of the fact that these lenses are advertised as rare Kardon lenses, I can find no evidence that the lens manufacturer had any relationship with Kardon beyond the fact that the Britar lenses fit Kardon and other LTM cameras. After Googling "Pam Britar", I found that most sellers included some reference to Kardon, either stating or implying that the PAM lens was an exceptionally rare Kardon lens. The prices of these lens are very high apparently as a consequence of the Kardon association claim. PAM was the Photographic Arts Mfg. Corporation of New York formed in 1946. They made the Britar lens and an 8mm "zoom" viewfinder as far as I can see. By 1951 the company name had been changed to the Starr Corporation (unknown products) and by 1994 they went out of business. By the end they were no longer in the optics business but rather the corporation was a bakery(!). So, does anyone have information on these odd lenses and perhaps why so many claim that they are Kardon lenses?
