X-S1 giving my DSLR a run for the money

That is one of the principal points that make bridgecams in general and X-S1 in particular so attractive for Internet quality photography - their long zoom. No need for heavy crop anymore. And  with 12Mp sensor some post-shot framing goes not have devastating effect either. However,  even with cropping, Pentax image makes clearer impression - maybe because of less heavy noise canceling.
