Took along my Pen F on a week and a half trip with its digital descendant, my E-P2, plus the X100. It was great to have 3 compact but very capable cameras along. The Pen F had the Zuiko 25mm F4, fairly slow but very sharp. I only used 2 rolls of film, but that still meant close to 100 images on this half frame 35mm. I used the Pen F when it was raining or when my digital cameras had no more juice left in their batteries (a particular issue since I only had one socket adapter for my chargers). The only real downside of the Pen is its very, very noisy shutter. Thankfully I had the X100 for times when I needed to be more unobtrusive. I thoroughly enjoyed using the F, despite its limitations; there is still such strong "muscle memory" and "eye memory" in me for shooting through an SLR viewfinder and manually focusing on a proper ground glass screen. It still feels the most intuitive to me. I guess that's because I've spent many, many more years shooting with compact film SLRs than I have shooting digital. All ISO 400 CVS Pharmacy own label film, home processed using Tetanol C-41 kit. Still working out the kinks in home processing and scanning, so lots of dust marks, etc.
