The ALPA Lens Family

The HR ALPAGON 23mm is the first choice for those photographers who need to cover as wide an angle as possible with a single “single shot”: On a 40x54mm sensor (like the IQ160 / 260/360, IQ180 / 280/380 or IQ 1 100 / IQ3/4 100 and later IQ4 150 from Phase One or the H6d-100c from Hasselblad), the diagonal field of view is approximately equivalent to a 15mm “full-frame” lens (35mm full frame).

For many reasons, the ALPAGON 32mm HR comes with a real exceptional position in the ALPA lens portfolio: Together with the HR ALPAGON 50mm and HR ALPAGON 90mm, it forms the “Holy Trinity” of the ALPA photographers. Its large 90mm image circle allows not only full adjustment ranges for perspective correction but also offer enormous potential for the stitching of single images: Our HR ALPAGON 32mm almost reaches the angle of view of the 23ers. Besides, the short barrel versions allow either the use of tilt/swing on a traditional ALPA or use on an ALPA 12 FPS.

Thanks to its image circle of “only” 70mm, the HR ALPAR 35mm presents itself as very light and robust travel and hiking solution. Those photographers who use it appreciate it as a reliable and, above all, light and compact companion, dimmed to f8 even with modern digital backs. Therefore, it is not surprising that you see the HR ALPAR 35mm more often in front of an ALPA 12TC: This combination is similar in many cases as a KB-DSLR with a corresponding focal length (24mm), but allows capturing with resolutions up to 100MP and one outstanding momentum. The high initial light intensity of F4 allows CMOS backs to focus perfectly even under difficult lighting conditions.

Given its compactness, one could easily underestimate the HR ALPAGON 70mm, but this impression is entirely deceptive: With its vast 100mm image circle it offers extreme reserves for the perspective and sharpness compensation (tilt and shift) and also the optical performance is entirely convincing. Since its focal length almost matches the image diagonal of the large medium format (40x54mm sensor), it corresponds to the usual definition of a standard lens and is characterized by an image that corresponds particularly well to human perception. Thus, the ALPAGON 70mm HR is ideally suited as an introduction to the ALPA system, especially since it makes an excellent figure on analog film: It also covers 6×9 film and then corresponds approximately to a classic 35mm in 35mm format.

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.

The Rodenstock / ALPA Macro Switar 5.6/105 mm is a high-performance lens for image scales of 1:4 to 4:1. The user can optimize the specific image scale via a ring-operated floating element which covers 1:3 to 3:1. Sharpness is extraordinary and only limited by diffraction. The ultra-low distortion nearly vanishes at 1:1 and beyond. The chromatic aberration is minimized and contrast performance is superior.

Designed in Denmark

Danish design is known for functionalism, simplicity, and elegance. For over ten years, Phase One Denmark has led the design of the Phase One Camera System lenses, driving the finest engineering and manufacturing partners to create a higher standard of lens to support the creative ambitions of professional photographers.

German Optics Engineering

Founded in 1913, Schneider Kreuznach is a worldwide leader in optics and precision engineering. Building on a century of German optics expertise, the Blue Ring Lenses for the XF Camera are unmatched in quality, with a unique individual focus calibration making unprecedented autofocus precision possible.

Japanese High-Tech Manufacturing

The manufacturing home of our lenses in Japan is where lenses are built by hand, each handled from start to finish by a single expert who oversees every component is flawlessly assembled. Established over a century ago, the Japanese optics industry is the optimal location for manufacture of the Phase One lenses.
