complan การใช้

At this time to differentiate between negatives taken with the older complan lens and negatives taken with the later minox lens, MINOX introduced an edge code in the negative.
Three years ago, Glaxo had pulled out of the fast-moving consumer goods market by selling off its popular brands like Complan and Glucon-D to Heinz, another multinational.
Complan lens and Minox lens are unit focusing lens, focusing from 8 inches ( 20 cm ) to infinity through precision gear linked to a focusing dial on top of the camera.
As the minox lens replaced the complan, so the enlargers had to change lenses : MINOX II enlargers were curved negative track and complan lenses, MINOX III enlargers were straight negative track and minox lenses.
