Get the FA43 instead of the DA40; it's still very small. Also consider the DA35/2.4 and DA*55 instead of it to start. And the DA15 is a very good alternative to the Sigma 10-20 if you find the zoom isn't imperative. I have a DA15 plus the very nice DA10-17 Fisheye (which is very useful because it has minimal fisheye distortion toward 17mm), and I'm considering adding the new Samyang 10mm MF prime that's due around December.
The DFA100WR Macro and DA*55 are both exceptional lenses; however, the FA77 is too. So this might be a better starting lineup:
Sigma 10-20 or DA15 or DA21
DA35/2.4
FA77
I have the AF540FGZ and I like it; however, Metz is a stong alternative many like, and the rumor that the 540FGZ will be replaced may eventually turn out to be true. But the AF540FGZ is a good choice right now, and much stronger than the AF360 which I had and sold.
