HR ALPAR 35 mm - mobile and versatile


Often we are asked at ALPA for the "raison d'être" of the HR ALPAR 35mm: A 35mm lens with 70mm image circle between a stellar 32mm and the extremely popular 40mm with 90mm image circle - Does that make sense? We think, "Yes":

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.

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.



APERTURE UNIT

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. Please consult the corresponding product pages for compatibility or ask your sales partner or ALPA directly.
