I have recently upgraded my Olympus OM-E-M1 Mark II camera to Mark III. One unique feature I like is the built-in Neutral Density feature, up to ND32 (5EV). It allows me to shoot the slow speed exposure under the bright daylight without being over exposure. I took it out to the Great Falls recently for testing by setting exposure time from one half to one second with f stop of 22. The results were pretty satisfied (for me). Here are some of the images I got.
