I’ve re-re-re-learned the lesson that light conditions in a conference venue is bad and I should always bring a proper strobe. Otherwise, pictures are dark or very grained (high ISO) or blured (mostly, unless your name is Arnold The Steel Grip). Ah, one more thing, don’t buy a DSLR with lens included, it simply is a waste of money. The kit lens is a piece of @#$%^&!, so just buy a body and then buy a proper (read: expansive) lens from Pentax (or Sigma). To quote the classics:
you are awesome
you have awesome camera
but it’s useless
without (proper) lens
Anyway, it’s always nice to have some photolog after events, even if the pictures are of bad quality.
