I love being able to open the aperture with the flick of a lever to focus, and then stop back down to my printing aperture by using the same lever. It really helps with consistency and ease of printing.

The Schneider Componon-S lenses are recognized industry-wide as a top-performing range of professional enlarging lenses. They are 6-element, 4-group lenses with special optical glass that are superbly corrected for a flat field, high-contrast transfer, and excellent definition over the whole field. With their high level of color correction, they are also ideal for top-quality color enlargements in enlargers using either opal lamps or cold-cathode lighting. The high performance of the Componon-S is maintained even at high magnifications and in distortion control setups.
Mechanically, the Componon-S lenses are specially matched to enlarging requirements. The aperture ring with a linear f-stop scale -- for focal lengths 135mm to 210mm with illuminated iris scale -- has click stops at full and half steps.
Componon-S lenses of 50mm to 100mm focal lengths are fitted in a barrel mount with a luminous aperture scale, click stops which can be disengaged, and a preset aperture control. With this system the iris can be opened after stopping down to the desired aperture for final cropping adjustment or fine focusing. A lever then returns the iris to the previously selected working aperture shown on the luminous scale.
The Schneider Componon-S range of top-level enlarging lenses superbly meets all optical requirements of professional enlarging.
