While the distortion might be acceptable for certain images, the vignetting rarely is… But of course, the correction parameters are not applied to raw files, nor are they in an easily accessible part of the metadata. In order to perform lens corrections the module uses Exif data of your image to. This makes the lenses easier (cheaper) to design and cheaper to produce, but it imposes correction in software, even for ooc jpgs (see the images from first post). Sets the color profile for output/export, causing darktable to render. Feel free to turn on your highlight over exposure guide and shadow under exposure guide.
Spend time getting the exposure correct as it makes everything else easier when it’s accurate.
Now some lenses are developed that have known abberations that can be corrected in software. Make sure that firstly you adjust the (1) lens correction and the (2) exposure setting. Some prime lenses especially didn’t really need any correction in post (e.g. So in-camera correction of the lens defects wasn’t a priority (and not really worth the extra costs, I suppose). Until fairly recently, lenses were designed to be as close to perfect as technically possible within a given budget (that’s what drove the development/use of different kinds of materials and aspherical elements). That is to be expected, as older cameras do not apply any lens correction (or store correction parameters). A virtual lighttable and darkroom for photographers.

Download Darktable - Darktable is an open source photography workflow application and raw developer. As far as distortion correction is concerned, I get better results in DT than in OOC jpg. A lens quality and specs is not defined by MP resolution (rather by like > purity of the glass, glass curvature homogeneity, CoC, TCA, and so on).
