I see that the list of supported lens varies by file type. I've been adjusting for the distortion manually. Can I get around this by converting to .dng after import?
Lens correction for all Micro 4/3 (MFT) lenses and cameras, including Panasonic and Olympus cameras, and other cameras (including Fuji X, Leica Q, plus many point-and-shoot models from Canon, etc.) happens automatically without any interaction by the customer.
Note: You should not expect to find any profiles listed in the popups, because the corrections are always applied.
If you are unsure whether your lens is supported automatically refer to the "info" button/icon on the Lens Corrections tab.
