Great to hear from you all. Thanks so much for your input.
I've just seen the Nikon S3 2000, a rangefinder, but I don't think it uses F-mount lenses. Looks like a great little unit!!!
I didn't realise the FM3A was that loud. When I compared it to my F90X it seemed much quieter! Diane, I might get back to you on that. Still looking.
