Reviewers from rtings have found the following***:
The PENTAX K3 Mark III is good for landscape photography. It feels well-built, and its fixed screen is bright enough to overcome glare from the sun. Its advertised battery life is excellent, and it's weather-sealed to protect from rain, cold, and dust. Unfortunately, its autofocus performance is disappointing for photography.
