Rodenstock / ALPA HR Alpagon 5.6/90mm, SB34, in Aperture Unit, custom made for ALPA by Rodenstock.
When looking at the MTF curve of the HR ALPAGON 90mm, many experts rub their eyes in amazement: Such a high resolution over such a large image circle (fabulous 120mm) is an absolute sensation. Not for nothing a reputation grows. The reputation precedes like a thunderclap and forms the upper degree of the “Holy Trinity” of ALPA. Especially for photography in the style of the Düsseldorf School or the New Objectivity, and these features provide excellent conditions: The large adjustment range of the HR ALPAGON 90mm allows without the need for falling lines. High resolution allows shooting with the most delicate details.
As an SB-34 version, the HR ALPAGON 90mm, thanks to its large image circle, allows for enormous flexibility, especially in the perspective correction. The perfect sharpness of the 90s makes it the perfect choice for all photographers, whose pictures have to function perfectly, as different sizes on exhibitions or billboards. If you are looking for perfect details and maximum resolution, there is no way around the HR ALPAGON 90mm.
Scope of delivery: The product images are sample images and often show the lens with an ALPA HPF ring (High Precision Focusing). This HPF ring is not included in the scope of delivery of the lens. However, ALPA recommends the use of an HPF ring for optimum handling.
Digital backs with electronic shutter (currently Rolling Shutter for Phase One IQ 3/4) are becoming increasingly available. The new Rodenstock aperture unit – with its almost round, 9-piece aperture pattern – optimally supports this shutter type. Besides, lens versions in short barrel can also be used on the ALPA 12 FPS with its built-in focal-plane shutter.
