Abstract: The present invention relates to new compound nanaomycin A and derivatives thereof represented by general formula: ##STR1## in which (a) R is H and R' is OH (nanaomycin A),(b) R is H and R' is NH.sub.2 (nanaomycin C),(c) R is COCH.sub.3 and R' is CH (acetylnanaomycin A), and(d) R is H and R' is OCH.sub.3 (nanaomycin A methyl ester).Nanaomycin A is a new compound of quinone type and its acute toxicity (LD.sub.50, intra-penetrial injection) in mice is 28.2 mg/Kg. Nanaomycin A and derivatives thereof are active on Gram-positive bacteria, trichophyton and mycoplasma and are useful as a medicament for humans and animals. Nanaomycins A and C are produced by culturing a nanaomycin-producing strain belonging to the genus Streptomyces aerobically in a medium to accumulate nanaomycins A and C in the cultured broths. The derivatives acetylnanaomycin A and nanaomycin A methyl ester have similar properties to those of nanaomycin A.

Abstract: A camera is equipped with a member bearing data to be photographed such as a date and the like and a data light focusing optical system for projecting the illuminated data from the data member at the front of the camera rearwardly with the object light toward the data photographing portion of the film. The data light focusing optical system is arranged so that the data light is directed to be incident on the data photographing portion of the film from a direction different from the incident direction of the object light. Provided in the front of the data photographing portion of the film is an object light incidence limiting member which is positioned parallel with the plane of the film and allows the transmission of the data light therethrough but interrupts the object light directed toward the data light focusing portion of the film.
