Developping Raw Files, AP 1.5.2.69 very often does not recognize camera data and subsequently will not perform lens correction. In Raw persona as well as in tone mapping persona (new HDR stack..) the display shows 0 or "no camera data" text instead of lens name when opening GH-4 Raw file(s).
This behaviour seems to change from time to time without notice. But in spite of investigating that for a while I could not find a reason behind that so far.
The only thing I can tell is, that the same Raw files opened with Photoshop CS 6 do not show any innormal behaviour and lens data are always displayed in correct manner. The same is valid for ACDSee Ultimate 10.
Please advice what I could try to improve that disturbing behaviour.
Edit: On Windows 10 notebook the problem seems not to happen.
Best regards
