SPECIAL SHOOTING MODES
PERSPECTIVE CONTROL
This assist function displays a frame showing the expected cropped
section of the image after a correction of the perspective of ver-
tical falling lines. Perspective Control helps to achieve a generally
straighter vertical line and straight horizon, which ensures a natural
image effect, specifically in architectural images.
The function “Perspective Control” calculates the image section
and the required distortion correction based on the actual panning
angles of the camera and the lens used. In effect, the camera ori-
entation during shooting (determined by internal camera sensors) is
the decisive factor and not the lines visible in the image object. The
function is therefore unlike automatic perspective control features
used for post-editing, which are generally based on the image con-
tent.
The functionality depends on the image file format used (JPG or
DNG). For JPG format images, the correction occurs directly in the
camera and the corrected image is stored. For DNG format images,
the relevant information is written to the meta data of the original
image. Image correction is done later on using a program like Adobe
Photoshop Lightroom ® or Adobe Photoshop ® *.

Notes
• In case of large panning angles, the distortion correction needed
for a complete perspective control would be too extreme. That is
why this function is automatically skipped or only partially used
where angles are too large. In that case, we recommend creating
DNG format images and effecting the desired corrections in a
post-editing step.
• The focal length of the camera lens must be known to use this
function. It is automatically detected when M lenses with 6-bit
encoding are used. The lens type must be entered manually when
other lenses are used ( Lens Detection ).
• A histogram will not be available for technical reasons, while the
function Perspective Control is active.
• The functions Digital Zoom and Perspective Control cannot be
activated at the same time. Selecting one of these functions will
automatically disable the other.
