What lenses should I buy for the olympus pen e pl5?
The PEN E-PL5 takes Micro Four Thirds lenses, so you have a wide choice. Without a particular subject in mind, I'd build a simple kit of three.
Start with an everyday zoom: the Panasonic Lumix G 14-42mm f/3.5-5.6 II covers the basics, framing like 28-84mm on full frame. For landscapes and interiors, the OM System M.Zuiko 9-18mm f/4-5.6 II gives you a proper wide end. For low light and a softer background, add a fast prime such as the Olympus M.Zuiko 17mm f/1.8.
Since the lens is what you'll keep for years, it's worth thinking about how much you'll carry and what you'll want later before you spend. As I say on the first camera page, the money goes further in lenses than in the body.
