The FA was designed for film cameras , so full frame and has an aperture ring and screwdrive focus. And a third to half the price of the new one!
The DA was designed for digital so has no aperture ring and has a SDM focus motor . As Pentax use an APSC size sensor ( smaller than full frame) the digital lenses MAY vignette (have dark corners) on a full frame camera.

hmmm there is no DA50mm.
There is a DFA50mm f/2.8 macro & DA*55mm f/1.4 both are very different so which one do you mean?

And the DA* has a extra 5 mm. It's a 55 mm, you know
Filter size: 58mm, instead of the 49 mm of the FA 50.
Martin.
Edit: Stefan, I think he means the DA*. Talking about F 1,4.
