Sony RX10 II Flash

Built-in Flash Test Results

Coverage, Exposure and Range
Decent flash range helped by the fast lens, with somewhat narrow coverage.

Coverage, Wide Angle

Coverage. Flash coverage was somewhat uneven at wide angle, leaving very dark corners and edges in our flash coverage test image. Narrow coverage at wide angle is common, though, and some of the corner darkening is likely from the lens itself. Illumination isn't very even vertically either, however we doubt that'll be an issue in most real-world shots. We no longer test flash coverage at telephoto, as it is invariably better, making wide angle the worst case scenario.

Normal Flash, ISO 200
+1.0 EV
Slow-sync, ISO 200
0 EV

Exposure. Our Indoor Portrait test scene came out a little dim in our normal flash test at f/4 and ISO 200, even with +1.0 EV flash compensation and a somewhat slow 1/50s shutter speed. You'll likely want to raise ISO sensitivity further in similar situations. Slow-sync mode was brighter as you'd expect, with its slow shutter speed of 1/13s capturing more of the warm, ambient light.

Manufacturer-Specified Flash Range

33.5 feet
ISO 1600

Manufacturer Specified Flash Range Test. The Sony RX10 II's flash range is rated at 10.2m / 33.5 ft. with Auto ISO. In the test shot above at 33.5 feet, the RX10 II chose ISO 1600 and produced a well-exposed flash image, so Sony's flash range rating is credible. We shoot this test shot using the manufacturer-specified camera settings, at the range the company claims for the camera, to assess the validity of the specific claims.
