HR ALPAGON 40 mm - The Workhorse

If the conversation comes to the HR ALPAGON 40mm, then the term "workhorse" usually comes up very soon - and quite rightly so, because, for many (professional) photographers, the 40mm is the standard solution for their ALPA. If you wanted to mark it as a "bread and butter" lens, you would be wrong, however: With its brilliant performance and its image circle of 90mm, it plays in the same league as the legendary HR ALPAGON 32mm, but is due to its slightly narrower angle same light intensity significantly lighter, more compact and therefore more robust. It covers (based on 40x54mm) still a comparable angle as a 28mm lens on a 35 mm camera and allows even on the so-called medium format back (40x54mm) even shifts of up to 16mm. A real companion and workhorse.

The HR ALPAGON 40mm can be found particularly often together with an HR ALPAGON 70mm in a photo backpack, bag or case. It is not for nothing that many newcomers to the ALPA system opt for this combination, not only for the focal length range but also for the optical characteristics of the two Optics perfectly harmonized.
