I did not have too much time with my OM 24mm f/2.8, or 50mm f/1.4, but I loved the results of my OM 50mm f/1.8 and pricey 85mm f/2.0.
The OP is looking to get a 50mm lens for right now. The OM-System has a lot to choose from in the standard focal lengths, depending what you are looking for. My latest 50 is the 50mm f2.0 Auto Macro. It is quickly becoming my go-to lens.
