It is often overlooked that landscape and architectural photography is not automatically equivalent to wide-angle photography: Often, detail shots enrich the meaning of an image path and topographical features also require the use of longer focal lengths. For these subjects and requirements, the HR ALPAR 180mm rounds off the ALPA lens portfolio. Since the use of long focal lengths usually leads to very low camera inclinations, its image circle of 80mm in practice is easy enough, especially as the resolution remains almost constant over the entire image field. With a weight of less than one kilogram, the HR ALPAR 180mm remains easy to transport and, with an aperture of 5.6, delivers perfect performance even with an open aperture.
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, Hasselblad X1D and partly H6D) 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.
