Thanks @heckflosse and @chasingshadows for your replies. This is all new to me… I had no idea that automatic selection was limited to Lensfun profiles. In fact, although I had heard of Lensfun, I had no understanding of what it was. 
I’ve just been reading the Lensfun site, and I see that my lenses are not listed under Supported Lenses, but they are listed in the “develop” section. It also said that Adobe profiles can be converted to Lensfun profiles using a script, but gave no information about how to do that. Since I already have the Adobe profiles for my lenses, conversion would be very handy, but I have no idea how to go about doing this.
Is anyone able to advise? TIA.
PS @chasingshadows… that link is giving a “500 internal server error” message. Any thoughts?
