The Pen-F was my gateway to the world of M43. I shot some wonderful images with it. At the time it was my only camera and I bought it for the retro looks, the IBIS and the wonderful monochrome JPEG mode. Since then, I have learned to process RAW (and shoot only RAW now), acquired an EM-1.1 with a 12-40 (that I prefer for most paid shoots or studio work) and also a GF1. I will keep the EM1.1 as my workhorse camera (weather sealed, battery grip and 12-40 are great for when I am working) but the GF1 is making me wonder if I need to keep the Pen-F. I have shot some wonderful images on the GF1/20mm combo so far The next thee are SOOC JPEGs, which is supposedly a GF1 weakspot. They look ok to me (of course they look better once I've had a go at the RAWs in LR). Aside from IBIS and the cool looks (not a priority, but I find that the Pen-F looks retro and is a conversation starter at parties and on the street, which allows me to build rapport with people), I really am not sure why I should keep it. The menus on the GF1 are simpler, as are the controls (I can easily one hand it like a Ricoh GR, adjusting shutter, aperture, ISO, WB and exposure comp). I like that the Auto ISO tends to hold to the lowest possible value, rather than the Pen, which seems to go for the highest value. Even the built-in pop-up flash is capable of producing decent images in very dark, almost black conditions (below). Another SOOC Jpeg that reminds me more of a Ricoh GR file than any M43 produced camera. The fact that it's "only" 12 MP with 12-bit RAW files seems to be irrelevant. I haven't seen any smearing or noise with the files either, whereas even in good light, I have seen some with the Pen's RAWs. I am wondering what I'd be missing, if anything, if I sold my Pen-F and used the EM-1 for my "work" and serious shooting, with the GF1/20mm for street, travel, fun etc. As far as I can tell, the IBIS, silent shutter and the retro aesthetic are the big ones. One big caveat is that the Pen-F has some sort of ineffable joy that comes with shooting it. Everything feels nice, the EVF in monochrome is a real joy to compose images with and it delivers flawless images every single time, so long as composition is good. IBIS is a gift from the gods when shooting in low light. On the other hand, the GF1 is a bit smaller, seems to have better AF (no, really), has its own aesthetic charm. And if anything happens to it, I can get another one for $100 ($300 if the 20mm needs replacement). Tell me what you think?
