Right. The possibility to override automatic detection is already 
implemented. OK, it's a nuisance that you first need to select the 
camera before you have all lenses presented. But that's not the biggest 
issue.

The key problem as of today is an automatic detection that is way off 
and which the user fails to observe.

A few ideas:

1) we could go back to the strict search rules. A lens would only be 
accepted from the database if there is an exact match.

2) we could add a second cross-check (maybe Levenshtein) of the found 
lens with the EXIF string. If the two differ too much (*) we reject the 
found profile and fall back to manual selection.

(*) what distance is acceptable needs to be found out by experiment and 
experience
