As mentioned in another thread or two, I rented a black Pen F for the weekend to check it out. I took it - along with my new E-M1 - on an 11 mile hike through the mountains of southern West Virginia. I had to make 10 water crossings over one of our rushing streams, and I was very cautious, to say the least. Some of the crossings were precarious, with water more than half way up my shin. Both cameras are insured, but a good hiking pole still is useful at times like that. The day started out gloomy and overcast, but turned partly cloudy and sunny by about noon. You can see the difference in the photos. I did some low angle shots with the camera on a short tripod, and the articulating screen was useful for that. I fiddled with the bold mono filter, and you'll see in some photos I filtered for green or yellow. I also tried B&W with a red filter. I didn't try the High Res photo option. I even did a video of a large, wide waterfall, but the file is huge, and I have no idea how to share it. I'll be sending the Pen F back tomorrow. I won't be buying one for myself, but it seemed to be a well built, quality camera. TT All photos taken with a Lumix 20mm/1.7.
