If you are looking for manual lenses, grab a minolta adapter and pick up a 50mm and 28mm prime for cheap! You can get a 50mm 1.4 and a 28mm 2.8 for under 75 easy. The adapter is 30.
I recently picked up a 35-105mm 3.5 pentax smc-a and LOVE IT. The adapter is again 30. I got that lens for $99.
I also have the panasonic 14-45mm lens 3.5-5.6 and love the look of the 14mm. 3.5 isnt bad and the lens quality is superior to all other kit lenses i've used/seen.
The 20mm pancake is a SICK lens made by panasonic.
