Wow. It has excellent shadow details. My people have dark hairs and dark eyes. So it's important to bring out dark details. Other than the excellent DR, water sealing body, and built-in IS, what else do you like about it? What Pentax lenses do you recommend?
Do not let me start here.. :-) Go to pentaxforums.com. Their lenses section in among best in the world.
It all depends on the task, in fact. As you could start with M42 Takumars, for example. But normally WR kit lenses are recommended if you need to get dirty (for starters :-) ). Limiteds, of course.
I have their kit-lens; the 18-55mm and it's pretty awesome! I'm using it on the GH1 but still, very very good. I have several other of their budget lenses too and all are awesome. Their budget lenses are some of the sharpest in their class - actually they transverse classes and place favorably along side semi-pro lenses.
You wouldn't need $2k to put together a great kit! More like $1K and that would be with 4 or 5 lenses. :)
It's unbelievable how nicely priced their gear is! Kinda the opposite of Panasonic... :P
