Thank you David. I also find on the Net about that $#*&*% knob of the 105mm f2,8: ...has a primitive form of focus lock which really doesn't work at all, unless you send it to Nikon to get it fixed. It's probably the one Nikkor in the world that's broken straight out of the box... ----- Original Message ----- From: David Rayfield <Rayfield@svsu.edu> To: List for Photo/Imaging Educators - Professionals - Students <photoforum@listserver.isc.rit.edu> Sent: Thursday, July 04, 2002 1:07 AM Subject: Re: OT What in the hell is that $#*&*% knob for??? > > >From page 199 of "The Complete Nikon System: An Illustrated Equipment Guide" by Peter Braczko, re. the micro Nikkor 105 mm f/4: "In 1977, the slightly improved AI version came on the marlet, and it can be identified by its chrome locking screw for the focus, which makes it easier to use this lens in a vertical position on a reproduction unit. The first serial number of this version is 186956, although lower serial numbers are possible." > -----Original Message----- > From: José Luiz <jlvasconcellos@infolink.com.br> > To: List for Photo/Imaging Educators - Professionals - Students <photoforum@listserver.isc.rit.edu> > Date: Wed, 03 Jul 2002 16:51:43 -0300 > Subject: OT What in the hell is that $#*&*% knob for??? > > Be patient dear friends, I know that probabily this is not the correct forum > for this question but it is driving me crazy and I do not have the guts for > the > nikon mailing list...
