I read that in a pop photo in 1969 I'm sure in one of those columns. I'm sure in other areas of Earth this is less than one meter. To 1:1 I think when you get bigger than 1:1 you could be in the micro area You are making things bigger. Not just getting closer than most glass is optimized for. Perhaps its defined differently with great authority somewhere but I cant imagine where. A macro lens is not just optimsed not for infinity but I think 3 feet it is flat field. So when you focus at something three feet away in the middle it is also in focuses at the edges of the field which would really as the crow flies be longer than 3 feet as its an arc from a circle otherwise.. You wide open your edges would also be in focus. The problem is there is no official handbook somewhere that is going to be the place to put a so called definition of such a concept as micro vs. macro. It may be that its just in the marketing realm. Is there an IS on it? An INTERNATIONAL STANDARD Drawn up by the International Organization for Standardization. Which I'd think there would not be. (ISO) Unless the ISO people have a PRF - Proof of a new International Standard on it. Written up a TS - Technical Specification on it. A PAS - Publicly Available Specification. In the end it could be just semantics; as Nikon has been calling macro micro the whole time and nobody sent them a five dollar ticket to their marketing people. Its not the 5 bucks its licking the stamp that gets you. What's the PAS, Kenneth? -------------------- Mark William Rabiner Photography http://gallery.leica-users.org/v/lugalrabs/ mark at rabinergroup.com Cars: http://tinyurl.com/2f7ptxb > From: Fred Hess <fredhess at phenix-visuals.nl> > Organization: Phenix Visuals NL > Reply-To: Leica Users Group <lug at leica-users.org> > Date: Wed, 27 Oct 2010 21:28:23 +0200 > To: Leica Users Group <lug at leica-users.org> > Subject: Re: [Leica] for nikon and/or macro enthusiasts > > The Photar-lenses are designed for 1.4 : 1 up to 17.5: 1. which is to my > opinion is photomacrography.
