Thanks a bunch!

In short, it seems that most of the reasons that would make my K100 perform better than the K20 are pretty much negated by better sensor design, so in theory, the K20 should perform a lot better than the K100. I wish that there were reliable measurements of this aspect of a camera's performance. > > > --M. > > > -- > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- > http://www.EnticingTheLight.com > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- > > -- > 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. -- The first step is learning to take great photos, the second step is learning to throw away ones that are merely good.
