Olympus produces three different 8×42 binoculars: the “Pro” (Olympus’ top model, see separate post), the EXWP I (waterproof roof prism model, see separate post) and this Porro model, which is not waterproof, shows acceptable optical and mechanical performance, but has a narrow field of view. Compared to similar models from competitors such as Nikon (e.g. Nikon Action EX 8×40, see separate post), the EXPS appears expensive for what it offers.
