– at 2 m: the exact sensor size of approx. 23.9 x 35.8 mm
– at infinity: (depending on focal length) approx. 7.3% (28 mm) to 18% (135 mm)
– less than 2 m: less than film size
Viewfinder magnification x0.72 (all lenses)

Metering principle The light reflected by a metering spot in the center of the 1st shutter curtain is metered.
The metering spot has a diameter of 12mm and therefore corresponds to approx. 13% of the full negative format or around 2/3 of the short side of the corresponding
frame in the viewfinder.
Exposure control mode Manual shutter speed and aperture setting, adjustment using LED light balance.
Flash  
Flash unit connection Via accessory shoe
Synchronisation On the 1st shutter curtain
Flash sync speed 1/50s; slower shutter speeds possible.
Flash exposure control Via computer control of flash unit or via guide number calculation and manual setting for the required aperture.
