Thanks for the support Richard In fact, I don't have yet this Elpro. But I have the other hardware. I have read that the 14-50 Vario Elmarit of the Digilux can focus down to 29cmm (a little more than a feet) with a rate of reproduction of 1:3.2 I have read (thanks David Young for your article) that the 'Cron 50mm with Elpro VIb can give a reproduction rate of 1:2.6, er on a film camera, minimum distance is 14 cm (5 inches). Given the excellent resolution of the summicron 50 on a Digilux, it's quite tempting. But I have no idea of the final reproduction rate. And I have no idea on how to compute it. Experimentation, it gives someting to do on a bad day. <---> Xavier F.
