Average Resolution Sensor: 12.0MP
Pentax Q-S1's 12.0MP resolution is not ideal for landscape photography but you can still achieve large prints with good framing and technique.

Pentax Q-S1's small sensor struggles in low light situations compared to larger sensors. No Environmental Sealings
Landscape photographs are taken outdoors and you should be prepared for all kind of weather conditions.
