I purchased the Lumix GX80 last December after my second Canon EOS film SLR finally gave up the ghost. Making the transition from film to digital was (and still is) something of a learning curve which requires you to get used to changing your approach somewhat.
This is a question that crops up all the time and it can really infuriate experienced photographers (e.g. Karl Taylor).
