Medium format prime lens for Phase One XF cameras.
The Phase One Schneider Kreuznach 80mm f/2.8 LS is the standard prime for the Phase One XF medium format digital system. LS = built-in leaf shutter. At 80mm on the 44×33mm sensor, it is roughly equivalent to 55mm on 35mm — a slightly wide-to-normal focal length. One of the most-used Phase One primes in studio and location portraiture.
80mm focal length, f/2.8 maximum aperture, built-in leaf shutter (electronic, full flash sync at all speeds), Phase One XF mount, covers 44×33mm sensor.
The 80mm f/2.8 is the 'standard prime' position in the XF system — versatile across portraiture, product photography, and environmental work. The leaf shutter's full flash sync enables large-aperture outdoor fill-flash without sync speed limitations. Compared to the Hasselblad HC 80mm f/2.8, the Phase One version is engineered specifically for XF body electronics. Wide aperture on medium format produces a shallower depth of field than the same aperture on 35mm.
Test leaf shutter across all speeds. Verify XF mount electronic coupling and confirm body-firmware compatibility. Inspect glass condition — Phase One lenses in rental and studio use accumulate cleaning marks. Check for any front element impact from studio handling. Test focus accuracy at f/2.8.
