The 3.0 inch, 921K dot Air Gapless LCD construction ensures good visibility of displayed image even outdoors. The electronic level indicator assists precise composition.

Pentaprism viewfinder for 100% FOV

Despite its compact size, the KS-2 features a glass prism finder with 100% field of view and approximately 0.95-times magnification (with a 50mm f/1.4 lens at infinity) to cover the entire field of view for easy focusing and framing.


Fully weather-sealed

With 100 weather seals throughout the entire body, your KS-2 gives you shooting confidence in any weather condition or outdoor setting, rain or sand.
