The lenses in the COMPONAR-S series are efficient enlarging lenses, reasonable in price, for the discriminating amateur. Enlargements with the four-element COMPONAR-S produce high-contrast and brilliant prints, from either color or black-and-white negatives. This lens type is suited for practically all magnifications of enlargement. Its optimal performance is in the area of 6:1 to 10:1.
The COMPONAR-S has a useful mount with an easily grasped aperture adjustment ring which makes the lens easy to use. An illuminated aperture makes it easier to use in the darkroom. The aperture adjustment ring with a linear scale has a click-stop at each full f/stop. By simply pulling down the aperture ring, the click-stop feature can be disengaged to permit fine adjustment of the aperture.
