HR ALPAGON 23 mm - ideal for landscapes and tight interiors
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).
While such image angles on (medium format) SLR cameras can only be realized with large optical "artifices", ALPA technical cameras allow a much smaller distance between the rear lens and the sensor. This freedom allows optimization for highest resolution and sharpness. Shooting with the HR ALPAGON 23mm impresses again and again with its richness of detail and the lively micro contrasts. The on-edge color shifts that occur in modern high-resolution sensors (due to micro-prisms in front of the pixels) can usually be easily removed using the "Lens Cast Calibration" function. Due to the large front lens, the use of a suitable lens shade is recommended.
The HR ALPAGON 23mm is the ideal lens, especially for spectacular landscapes and narrow interior spaces.
The ALPA ALPAGON 5.6/23 mm is now officially available as a Short Barrel 17 lens with an aperture mount. This version with a recessed lensboard was one of the last wishes of our late Chinese partner Fred Zhou. In his memory, we first offered this version exclusively for our partners in Beijing. Now we offer this special version for all partners and customers. The short-barrel version is fully integrated into the ALPA world.
- Version for aperture mount (Copal 0 feasible but not recommended)
- Integrated ALPA HPF ring with meter and feet scale
- Integrated rear lens protection against mechanical damage
We are working on a version optimized for use with X-Shutter and Copal 0. This version is expected in Q3 2021.
Warning: If a short barrel lens is attached to an ALPA body without an appropriate adapter, mechanical damage to the rear lens element and the camera is possible. The lens cannot be used with the ALPA 12 FPS.
