RODENSTOCK ROGONAR-S 75mm f4.5 LENS(new)
The universal lens Rogonar-S has a relatively simple optical de- sign and so a very attractive price. But the very high perfor- mance capability of this lens makes it ideal for the high re- quirements of demanding amateurs or professional labs.
The main application area of the Rogonar-S is enlargement in the scale range required for photographs in the standard for- mats. In this range, the lens with 4 elements in 3 groups pro- vides high-quality results with only low light fall-off to the pic- ture margin. Stopping down by 2 to 3 stops is recommended for optimal contrast und sharpness up to the image corners.
The recommended scale range can also offer some interesting possibilities for cropped enlargements.
It is equipped with a click- stop diaphragm which can be disabled on the models from 50mm to 105mm focal length for stepless control which is helpful for the use of analysers or timers with pre-set exposure time mode. All models from a focal length of 50 mm on have an illuminated aperture display and a practical pre-set aperture for fast switching from fully open to the working f-stop.
