A fixed focal length prime lens like this, you zoom with your feet or you compose with what you've got. This lens is good indoors in a large room or assembly, gym etc. Not across the table. For that, I say get the 20mm Panasonic.

It's a matter of choices.

Whatever's the case don't be intimidated by brand new prices. Buying very affordable used lenses is one of the great benefits of going with micro four thirds.
