Richard Is there a reason why you do not se planars faster than 2,8 and summicrons faster than 2,0 ? or is a summilux 1,4 just a fast summicron ? I am asking questions here in a field I know nothing about so please excuse me if there are faste planars etc. best Ruben ----- Original Message ----- From: "Richard Knoppow" <dickburk@xxxxxxxxxxxxx> To: <rollei_list@xxxxxxxxxxxxx> Sent: Thursday, May 26, 2005 1:24 AM Subject: [rollei_list] Re: OT - Bokken (was: Question on operatingand on screen for Rollei GX and Hood) > > ----- Original Message ----- > From: "Marvin Wallace" <Marvin0@xxxxxxxxxxxxxx> > To: <rollei_list@xxxxxxxxxxxxx> > Sent: Wednesday, May 25, 2005 3:55 PM > Subject: [rollei_list] Re: OT - Bokken (was: Question on > operatingand on screen for Rollei GX and Hood) > snip.... > Five element lenses were used in the f/2.8 Rollei cameras.
