Please allow the user to manually choose the manufacturer and lens model as Adobe does in Adobe Camera Raw. This lets the photographer select the correct lens in the lens correction database when the photographer uses a completely manual lens for which the RAW file will not have the data for manufacturer, lens model, f/stop etc. Similarly, when using electronic lens adapters such as the Metabones adapter for Canon EOS lenses on Sony alpha series mirrorless cameras bodies (e.g. a7r2), the Raw file EXIF data has the wrong manufacture and lens model because the electronic adapter must make the Canon lens appear to be a Sony lens model of the same focal length and f/stop. For example, if the widely used Canon 24-70mm f/2.8 L II USM is attached via a Metabones adapter to a Sony a7r2 body, the EXIF data records the lens as a Sony "24-70mm F2.8 G SSM II". The other EXIF data for focal length the zoom was at and exposure f/stop are correct. In Adobe Camera Raw's lens corrections, I can simply select the Lens Profile Correction for the "Canon EOS 24-70mm f/2.8 L II USM" and have the proper lens corrections applied. Similarly, if I use a Rokinon 14mm f/2.8 completely manual, no electronics, lens on a Sony a7r2 body, I can select that Lens Profile Correction in Adobe Camera Raw despite the lack of any EXIF lens data in the Raw file. At present, the only way to have Affinity Photo Develop apply the correct LensFun database corrections is to use ExifTool and change the data in the Raw file before Affinity opens the file. This is both time-consuming and I would rather not tamper with a proprietary Raw file format. Thank you.
Recently I've grabbed my old Panasonic again. [Leica lens, 5MPix (2560×1920), 12x opt zoom, f/2.8] Nothing stellar by now, but still acceptable camera. The problem is: Automatic lens correction does not work for its photos in Affinity Photo. But according to http://lensfun.sourceforge.net/lenslist/ it should be supported. I've tested trial version of PTLens.on Windows and darktable on Linux and both handle the photos correctly. Tested with latest stable AP 184.108.40.206 on my laptop. Tomorrow I'll confirm the bug with latest beta of AP 220.127.116.11 on my desktop. I really hope it can be fixed before releasing upcoming AP 1.6.
