When a new Leica M comes along it’s sure to raise eyebrows. As the German godfather of 35mm photography attempts to balance new features with traditionalism, Ian Farrell finds out if the M Typ 240 measures up as a serious photographic tool.
Leica M Typ 240 review – Dynamic range
In everyday use, the M delivers the kind of dynamic range you’d expect of a digital camera in 2013. In JPEG mode, highlights tend to blow rather easily, but are recoverable in DNG raw format. In our lab tests, we recorded 12.57EV of dynamic range in a DNG file, which is easily enough to rescue overexposed skies and recover lost shadow information.
The M’s pulled ISO 100 is not a real ISO setting, but rather a software workaround to allow shooting with wide apertures and long shutter speeds in brightly lit conditions. Typically, these software pull-ISO settings work by overexposing the image when it’s captured, then pulling back the brightness in the same way that you might in Adobe Camera Raw post-capture. Hence, there is not as much room for correcting blown highlights at ISO 100 as there is at the sensor’s native ISO 200 setting.
