[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have two asphericals. One is still new in its box. I liked the aspherical so much, and was so sceptical (perhaps wrongly) over the accuracy of moulding aspherical surfaces that I bought another "just in case" when it was discontinued... Sounds like it may have been an inadvertant good investment. I have already retired ;-) FD >________________________________ > From: John McMaster <john at mcmaster.co.nz> >To: Leica Users Group <lug at leica-users.org> >Sent: Saturday, 10 November 2012, 9:25 >Subject: Re: [Leica] 6 bit permanent flange adapters: has anyone tried one? > >You have an aspherical (rather than asph)?
