Rodenstock APO-Rodagon-N 105mm f4 Enlarging Lens

An ideal enlarging lens for film formats up to 6x9 cm, the Apo-Rodagon-N 105mm f/4 from Rodenstock is well-suited to general black & white and colour enlarging applications, and can also be used as a high-resolution macro taking lens for film and digital cameras. 

Using a seven-element optical design, this apochromatically corrected lens fully eliminates colour fringing and spherical aberrations to benefit both color and monochrome reproductions. Its recommended working aperture is f/5.6, and its recommended scale range of 2x to 15x benefits making mini enlargements up to mural-sized prints. 

Additionally, for ease of use, the lens is fitted with an illuminated f/stop scale, a convenient preset aperture setting, and a click-stop diaphragm that can be de-clicked depending on preference.

APO-Rodagon-N Lenses

The apochromatically corrected high-performance lenses of the Rodenstock Apo-Rodagon-N series guarantee perfect re- suits which will satisfy even the highest demands.

The correction of these excellent lenses with up to 8 elements was taken to the absolute limits and so ensures the full elimi- nation of irritating visible color fringes on high-contrast struc- tures. All monochromatic imaging errors have also been great- ly reduced to give this lens type its unsurpassed image reproduction performance.

The advantages are clearly visible in both color and black and white enlargements. The Apo-Rodagon-N is therefore the am- ateur’s and professional’s first choice whenever the very high- est reproduction quality is required.

The optimal working aperture is reached by stopping down by only 1 to 2 stops.

For the use of these lenses as taking lenses for close up and macro photography with 35 mm SLR cameras as well as for use as high resolution taking lenses with CCD still and video cameras, the same applies as to the use of the Rodagon; how- ever, the definition and the brilliance is still a little bit better.

All Apo-Rodagon-N models have a click-stop diaphragm and an illuminated f-stop display. They also offer a pre-set aperture and allow the click-stop to be disengaged for stepless control which is helpful for the use of analysers or timers with a pre- set exposure time mode.
