[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]My feeling is that a Qx with a 24mm f/2 lens and 100Mpx sensor (x = 4? 5?) would be all I?ll ever need from now on. That would give an EFL range to 150mm or so with enough pixels to put a 13 x 19? image on my screen or wall. By 2030 I?ll be lucky if I can see to compose a picture or view a print! ?howard > On Jun 28, 2021, at 2:56 PM, Frank Filippone via LUG <lug at > leica-users.org> wrote: > > I am of a similar mind to Howard.
