The GF30mmF5.6 T/S is a wide-angle tilt shift lens with the focal length of 30mm (equivalent to 24mm in the 35mm film format). It suppresses distortion and ghosting, typically seen with wide-angle lenses, to achieve a high level of image resolution.
This lens meets professional needs in landscape photography where everything within the frame is in focus from grass in the foreground to distant mountains, or in architectural photography with distortion characteristically seen when shooting tall architectures is corrected.
