Do those new lenses have a fixed outer size? Otherwise every zoom movement will suck in some air, causing changing humidity and condensation inside. However, I guess there's no major 'fog' problems within lenses and sensors? - Martin -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
