>> Hi all
>> I have a problem this morning when editing the raw files I just made.
>> (I'm using 5.8.0 on windows)
>> I have a camera LUMIX FZ300, and I have imported pictures into digikam.
>> When looking at the RW2 file from digikam it sounds correct and the JPG too
>> (I used RAW+JPG in my camera)
>> Problem comes when I'm using the editor to open the RW2 file, it is
>> presented with a high distorsion. So I select the automatic lens correction
>> menu, and I see the model proposedis FZ150.
>> so I select FZ200 (as it uses the same lens than FZ300) and apply it, and
>> now it is ok.
>> for information, the option "use metadata" is selected  (it indicates
>> partial match and model used is FZ150)
>> That could be ok except that I just opened another RW2 file I took 2
>> weeks ago with the same camera and the result is completely different (with
>> same option). By default, the picture doesn't show any distortion in the
>> editor. Only difference I notice is that in that case "automatic lens
>> correction " is not activated unless I click on "use default settings",
>> and in that case the same model is selected (FZ150) and this conduct to an
>> important distortion)
>> so my questions are  :
>> - why there is a different behavior when editing 2 differents raw (taken
>> by the same camera), and more generally how to get a normal picytire when
>> opening a Raw file
>> - why , while  "using matadata" is selected, the model is FZ150
>> - how to get FZ300 model in the list and to  get it selected by default
>> Hope I've been clear enough, if clarification needed, I can send some
>> screenshot
>> thanks for your help
>> frederic
