It's not a Macro lens, but it can focus down to 1:4 magnification making it a useful near-macro. Macro is one of the most abused terms out there for lens designations, very few zooms have real macro capability, although there are a few which can do 1:2 magnification (the real minimum to be a proper macro lens) but typically lack the flat field projection which is a requirement for most macro work. There are only 2 true macro zooms of which I'm aware, a Vivitar Series 1 whose specs escape me and the Micro-Nikkor 70-180 AF-D (Nikon calls its Macro lenses Micro-Nikkors). -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
