Aperture Series: Dynamic Range Outdoors (46mm)

This aperture series show us the X Vario lens performance, but also shows clear limits to the sensor dynamic range in an outdoor scene.

Shot at 30.7mm zoom setting (46mm full-frame equivalent field of view). ISO 100.

Exposure

Examination of the raw file using RawDigger shows that this example exceeds the dynamic range of the sensor: shadows are OK, but highlights (cloud detail) is gone and cannot be recovered; it is blown-out in all three color channels. It is a difficult scene; there are few mid-tones, mainly it is dark tones and bright highlights with not much in-between.

The ideal camera has at least another stop or two of dynamic range (e.g., the Sony RX1R). With the X Vario, care is needed with exposure as many field shots made clear, this one being just one example suffering from highlight loss.
