I'll be traveling for a couple weeks in late February, a vacation which will included daily shooting of ruins in the rainforest. I'd really like to travel light, and yet, I may use the images later for a publishing project. I wanted to float the question here about using my M4/3 cameras for this trip, vs. hauling all the FF gear. I have a E-P1, and was considering a EPL1 (or EPL2 if available in time) to compliment it. If shooting carefully, watching the iso setting, using a tripod when under the dark canopy, will these cameras suffice for a book publishing project, where the image will not be enlarged significantly? I'm familiar with the E-P1 image quality to be just about convinced that it will do the job, and save me a lot of agony while traveling. Does the EPL1 improve on image quality at all over the E-P1? Noise in shadows any better?
