Best budget lens for the olympus pen e pl7?

For everyday shooting, I'd start with the Panasonic Lumix G 14-42mm f/3.5-5.6 II. It frames like 28-84mm on full frame and covers most situations. The Olympus M.Zuiko 14-42mm f/3.5-5.6 EZ is the same kind of kit zoom if you prefer Olympus.

For people and low light, a fast prime will do more for your pictures. The Panasonic Lumix G 25mm f/1.7 gives a 50mm-equivalent view, which is what my first camera guide suggests. The Yongnuo YN25mm f/1.7M is another option at the same focal length.
