The Pentax K-3 II aims to improve on the K-3 with better continuous autofocusing, in-body image stabilisation and never before seen features like Pixel Shift Resolution and Astrotracer. Callum McInernery-Riley investigates
Our Applied Imaging lab test chart shows that at a base ISO sensitivity setting of ISO 100, the K-3 II can achieve 12.3EV. This is a very good, but fairly standard dynamic range score for this type of sensor, and indicates raw files should contain plenty of recoverable shadow detail.
At ISO 1,600, a dynamic range of 10.8EV is achieved, which is still very impressive. When pushed past ISO 1,600, dynamic range drops by around 1EV per stop of ISO sensitivity increase thereafter.
