Viewfinder principle
Large, bright line frame viewfinder with automatic parallax
compensation.
Eyepiece
Calibrated to -0.5 dpt.; corrective lenses from -3 to +3 diopter
available.
Image field limiter
By activating two bright lines each: For 35 and 135mm, or for 28
and 90mm, or for 50 and 75mm; automatic switching when lens is
attached.
Parallax compensation
The horizontal and vertical difference between the viewfinder and
the lens is automatically compensated according to the relevant
distance setting, i.e. the viewfinder bright-line automatically aligns
with the subject detail recorded by the lens.
