Since weddings came up recently I thought I'd mention one lens I use a lot: M70-150 f/4.
This is, of course, manual focus and green button exposure, but the focus and zoom share the same ring so you can zoom in, focus, zoom out, compose, and shoot, all very quickly. It's really sharp wide open, has good flare resistance, is a small and narrow lens compared to the 70-200 f2.8 stuff, and costs around $80. Compared to our Sigma 70-200 f/2.8, the Pentax is sharper at 70 and the Sigma is a little sharper at the long end. The Sigma costs 10 times as much, autofocuses well, has A mode, weighs maybe twice as much, takes much more room in the camera bag, but is a good lens otherwise. We have both, my wife uses the Sigma on a tripod, and since I got the Pentax 70-150 I don't feel any need for another Sigma or Pentax bazooka.
