Thanks for taking time to send your very interesting (as usual), and comprehensive, comments.

Modern as in late 70's early 80's?, true, not exactly inspiring, but good enough to be advertised and sold as a viable entry level alternative to Zeiss.They always had a V-good reputation for their rangefinder optics. > The main advantage for the Yashica system was that it had maybe ok > sometimes > maybe better than ok optics but you could put Zeiss made in Japan stuff on > it which really was pretty good.

Its a lot more difficult than it looks. It is indeed!!!! though if I consider I only started on macro about 3 weeks ago I hope to able to contend that the results aren't all that bad,(it makes a change from hundreds of tons of hot iron, steel and steam, which doesn't tend to wilt within the hour, and still brings big metering problems - they're so black) > You need to stop way down and use an ultra fast shutter speed at the same > time.

Nope, I'm not going to scratch my lovely lamp to prove anything, maybe if I rub it the genie will bring me a 60mm Elmar.

I'm sure this happens all the time.
