Will the Pentax dslr siblings work well with extension tubes and other close-up gear like the helicoid focusing adapter? I rarely do any macro work, but sometimes like to get close to show detail for eBay sales or to just get a little closer or less DOF when using some lenses in the 85mm - 200mm range. If I wanted a wide-ish zoom, which would be a good choice for close-up work? Has anyone use the M24~35 zoom on one of these cameras? How'd it work out?
