Best wide angle lens for the olympus om d e m10 mark iii?

For the E-M10 Mark III, my pick is the Olympus M.Zuiko 7-14mm f/2.8 PRO. It frames like 14-28mm on full frame and holds f/2.8 across the zoom, which is hard to beat for wide landscapes and interiors.

If you want something lighter for everyday use, look at the Panasonic Leica DG 8-18mm f/2.8-4, which covers 16-36mm on full frame. The Olympus M.Zuiko 12mm f/2 is a small prime that frames like 24mm, and it's a good choice if you'd rather carry one fixed focal length.
