I did develop the film, but the one from Hassy SWC (TX-400 in another post) looks good and sharp so the film processing is probably not an issue. I think I need to do better testing tomorrow, to laid these questions to rest. I will test it with the other lens too. I have a 150 Fuji and a borrowed 210 Symmar-S On Tue, Oct 16, 2012 at 11:25 PM, Mark Rabiner <mark at rabinergroup.com>wrote: > I you mean the Nikon 90mm f/4.5 > NIKKOR-SW lens its s stellar performer. > Which f stop were you shooting at? > Is it you that's developing the film? > > > Mark William Rabiner > Photography > http://gallery.leica-users.org/v/lugalrabs/ > > > > From: Richard Man <richard at richardmanphoto.com> > > Reply-To: Leica Users Group <lug at leica-users.org> > > Date: Tue, 16 Oct 2012 22:22:31 -0700 > > To: Leica Users Group <lug at leica-users.org> > > Subject: Re: [Leica] OT: large format lens vs. medium format lens > > > > Well, you are probably right that I need to lock down as much variables > as > > possible.
