I just updated my OM System OM1 to FW1.5 along with latest Photolab 6.6.192. My custom presets for RAW files changed regarding distortion control… the “Constrain to Image” option became unticked. There is a mention in the 1.5 firmware update about changes to the perspective control feature of the camera. Maybe that has caused this issue?
P.S. I never applied the perspective control feature to my in camera RAW (or JPG) files.
