The Pen F has a few jpeg based features that are already well thought of. Fuji (mostly) and Olympus have been developing their jpegs to new heights in film simulation and usability and the newest Olympus offering aims to simulate the look of Kodak Tri X film (or any mono film with a strong mid tone curve and rich, gritty contrast).
The camera has become a solid friend, out performing the OMD EM5's enough to be considered the safer bet in work conditions. The Tri X-looking mono stirs up memories of long hours spend in my dark room, looking for the magic image and taking every little morsel offered. I prefer a slightly less contrasty image with brighter and lighter tones and clean, tight grain (more FP4 like), but the look is genuinely "filmy".
