What lenses should I buy for the olympus pen e p7?

If you don't have a particular subject in mind, I'd start with a standard zoom and one fast prime. The Panasonic Leica DG 12-35mm f/2.8 covers roughly 24-70mm on full frame and keeps a constant f/2.8 across its range, so it's my pick for everyday shooting.

If you'd rather carry just one lens on holiday, the Olympus M.Zuiko 12-100mm f/4 IS PRO reaches about 200mm equivalent. It's a bigger lens to carry, so it only makes sense if you want that range in one piece.

For portraits and low light, the Olympus M.Zuiko 25mm f/1.8 gives you a 50mm-equivalent view and a bright aperture in a small package.

Before you buy, check the focal length converter against the framing you like, and read how to choose, in three questions if you're still deciding what you'll photograph.
