This is a beautiful enlarging lens in clean condition. In Komura's original advertising for them, they said that 'the Komuranon "S" formula corrects aberrations that occur in the visible light spectrum and uniquely cuts off infrared and ultra violet rays - the invisible part of the spectrum - to which the paper is sensitive. This results in superior contrast, resolution and color saturation.'
This one is in near mint condition with light wear. The glass is clean and scratch free with no haze or fungus and everything works perfectly.
