50mm 1.4 first impressions

Just picked up a 50mm 1.4 off ebay. Firstly it seems that its pre AIS and therefore im running totally blind, can only use in manual mode with no metering. But thanks to the historgram im getting somewhere. Its taking a lot getting used to manual focus with the little green light. Any tips on manual focus??
All taken with my D50.
I have only run a smart sharpen off these. Straight off the NEF.
Here are 2 shots that I would like to show.
The first is a portraite
cropped
2nd is a shot of the top of the baby pram showing some bokeh at 1.4
cropped
So what do ya think??
Thanks
