This would mean that symmetrical lenses such as the super angulon and CV 15 mm will still vignette and the longer lenses, such as the 90 and 135 will be less good than on a non-tweaked filter, but the majority will have a good engineering compromise, at least as good as current DSLRs using designed for film lenses. Hopefully there will still be no AA filter :-) Frank --- On Fri, 14/8/09, Richard Man <richard.lists at gmail.com> wrote: > From: Richard Man <richard.lists at gmail.com> > Subject: [Leica] So how about that M9 sensor?! > To: "Leica Users Group" <lug at leica-users.org> > Date: Friday, 14 August, 2009, 10:31 AM > Most M9 rumors are practically > agreeing with each other (meaning > either people keep copying others' posts, or may be the > rumors have > legs), but few technical details emerge.
