You may be surprised by the macro on the little Pentax-F 35-70mm, which you may already have, and if you don't you may find one in a ditch on the way home. Very common, very inexpensive, very under-rated IMHO.
If you need to get closer than that, the Takumar 50mm f4 (or one of it's later incarnations) would probably fit the bill nicely - goes to 1:2. Or, if work is paying for it, tell them nothing but the Vivitar Series 1 90mm f2.5 Macro will do. : ) Darren Addy Kearney, Nebraska -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
