The DA21/3.2 Limited is what I'd recommend. While a little tighter FoV compared to your MX + 28mm setup, it's close and it is an excellent performing lens.
I personally would never buy a Sigma lens. -- Godfrey godfreydigiorgi.posterous.com -- 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.
