Have bought this bag because of the reviews for an Olympus OM-D E-M10 with the rather large M.ZUIKO Pro 12-40mm Obejktiv: Unfortunately, this combination does not fit due to the tighter downwards becoming fit, for a 45mm / 1.8 or the EZ-14-42 kit lens however would be enough space. Problem is precisely the objective diameter at the bottom, the width UDN height of camera bodies on top go off. Processing and raincover are impeccable, a star deduction for my opinion bad price / performance ratio.
