Panasonic TZ60 RW2 support
Darktable hasn't open my TZ60's raw pictures at all. In LT I can see some pictures in a folder, but double click doesnt open it at all.

Thanks for the sample file. These cameras have 4 different raw modes (16:9, 3:2, 4:3 and 1:1). This file is 3:2. To add full support for the camera we need one file per each of the modes. Could you change that setting and shoot a raw file in each of the other modes and attach it here?
#2 Updated by Pedro Côrte-Real over 5 years ago
Support for this file has been added in this commit to the current development version (what will become darktable 2.0):
It will be backported into darktable 1.6 so will show up in 1.6.3.
To improve the support you can provide some extra raw files:
1) the other 3 modes as I described before
2) samples shot with each of the whitebalance presets (e.g., Daylight, Fluorescent, etc)
3) samples shot at each ISO level with a target that includes very bright and very dark areas

additional work still pending...

The extra raw modes are now supported:
The only missing bit is the noise profile
#13 Updated by Pedro Côrte-Real over 5 years ago
All your recent samples seem to have black margins. Do you have some kind of after-market lens hood? Anyway, there's nothing in the raw processing itself that will fix that. You can provide samples to lensfun for automatic correction of color aberration, distortion and vignetting:
#15 Updated by Pedro Côrte-Real over 5 years ago
I see very serious black areas around the edges in your test shots, not really vignetting something is really blocking the lens. But anyway the reason for 3:2 to have more vignetting is that it's the actual resolution of the sensor, everything else is just a crop. That's not really something to be fixed by the raw loading. You can apply automatic vignetting reduction by calibrating the camera+lens with the instructions as provided in the link I posted above.

Actually for m4/3's the native aspect ratio should be 4:3 :)
However, the image indeed seems like a case of crappy lens. And it's hardly surprising and fairly common on these compact superzooms.
The aspect ratio probably doesn't matter too much, lenses exhibiting vignetting often only do so, at their larger relative apertures.
The sample image you provided was shot at f3.3, which is the largest aperture for that particular lens at that particular focal length. Thus the vignette.
The only proper solution would be to generate correction data for lensfun, as Pedro already outlined. So it's not a darktable issue.
