In praise of primes - which next?

Heya Malv, I am kinda in the same boat and just started a thread I hope will help me (didn't see yours till just now) so check there too and maybe they can help you. I was linked a good website with reviews on many lenses, even 3rd party glass, http://slrgear.com/reviews/showcat.php/cat/45 . They don't have all of them, but theres also http://www.photozone.de/pentax  which has a few different lenses. Here's what I've basically found so far.

Your choice of FL will basically come down to how much you want to spend and how much you want to move. I am leaning towards 15/50/100, something like that. As for specific lenses, the FA43 LTD looks like it will fill my 50mm gap, although it's a little more spendy than I had hoped. The FA100 2.8 is my sure bet for my longer range portrait lens. My only question is how the 43 and the other 50s compare, as I'm hoping to find out with some help from the more experienced people.

In the end, pentax forums dot com has a lot of user reviews of every lens you can think of.
