JBrunner, What do you know, that what I shoot. I'm not too familiar with the s series lenses. I've heard that they are fine in the shorter focal lengths but you will notice a difference in the longer focal lengths. I've got the ps 50mm, ps 80mm & the ps 110 f4 macro lenses. None of them focus terribly close. The 110 f4 macro only goes down to 1:4 magnification. I also have the S36 extension tube, and paired with the 110 f4 macro its close to 1:1. If you'd like to play with a sqa before you buy, let me know I'd be happy to let you play with it.
