Pentax K-S1 Review
Specifications
The Pentax K-S1 shares the majority of its hardware with the K-50, the current weather-sealed entry-level model. It has been improved in several areas, including the sensor, LCD screen, and optical viewfinder. Unfortunately, the electronic level has been removed, as has the weather sealing and the second control wheel.
