I'm trying to figure out if the new Pentax DA* 16-50mm and 50-135mm lenses are worthy replacements for my Sigma 24-70mm and 70-200mm lenses. All four lenses have a max. aperture of f2.8. All would be used on K10D bodies. I've had the former two lenses for about 5 years now (since the MZ-S that I no longer have) and am thinking that it's time to get something better mated (?) with the digital bodies I own.
Experiences? Opinions? Thanks. -- 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.
