Olympus OM-D E-M10 help with lens choice.

Hi Everybody.

I sold my Nikon d7000 about a year ago and have not owned a camera since, but have decided i miss shooting so much i have decided to take it up again. After looking for a long time and bearing in mind Budget and that i now need a lighter set up i have decided i really like the E-M10.

I need help choosing a couple of lenses, first i need one to shoot bands these are amatuer bands that usually play in local venues that are usually not that well lit but do have a decent amount of stage lighting and i can get as close i wish to the action so i do not need a long lens.

Second a lens that i can take out with me to car shows and the like and maybe also be able to use as a street shooting lens.

My budget will be about £500 for the lenses or is there one that will do both jobs?

Thanks for any help you can give.

Cheers Paul.
