I am going to guess that you do not want the dark corners. Use the setting in the bottom and then develop the image. Use the Inpainting brush on the corners.

Vignetting is caused by geometry of the lens, the centre of the image is always going to brighter than the edges, corners are even further away. If the sensor was large enough you would see a circle with the subject in the middle and the unexposed area (the shadow caused by the lens's body) surrounding it. So software just crops out the image according to some formula.

Old Bruce is totally right, only to add topics for the sake of completeness:

• Photo uses all pixels of raw file, whereas (at least) Canon cuts off up to 24 edge pixels which reduces the vignetting problem. I assume the same effect here as the first screenshot is relevantly cropped to exclude problematic corners
• in rare cases of new cameras/lenses (meaning 1-2 years after market launch) there could be actually issues in Develop Persona to correctly interpret raw files. 
• If you upload the RAW file (and reference file from first screenshot) we could analyze further

Thank you.

If you open the RAW file then go to View > Assistant manager and set the RAW engine to Apple then restart the app and re open the file does the vignette still appear? No. It works.

I am having the exact same problem with Affinity Photo and RW2 (RAW) images from my Panasonic Lumix FZ80.  I can open the same RAW image in Irfanview or Windows Photo with no vignetting.

I can't see that exact lens profile in AP

But any of the 3 Panasonic "compatibles" get rid of the vignetting

See which one best matches what you see in Irfanview or Windows Photo and use that for now

 Irfanview and Windows Photo are just displaying the jpeg image contained inside the RAW file, they do not actually process the file. I downloaded and opened your file in AP and see the vignette, and that AP does not yet support that camera/lens. I also looked at it in Lightroom, and discovered that the lens correction is built in, and LR can read that in the RAW file.

 

@carl123 beat me to posting, so I just stopped with the above, but yes, one of the Lumix lens in the profile seems to correct it.

Thanks for the explanation!  But what do I have to do to get AP to work with my camera?  It is a Bridge Camera with an integrated zoom lens so I cannot change lenses.  And it is a popular camera model, so why doesn't AP support it?!

Serif use LensFun library for RAW developing. The camara model isn't in the list of supportet lenses. If you wish to have it in the list have a look at following site.
