I have been using a panasonic gf3 with 20mm and kit lens for the past 2 years as a travel camera/video camera. I am happy with the result when there is sufficient light. However when I push the iso above 800, the images loses all the details. I am looking at the EPL5 as a budget replacement. Based on the reviews and sample images it seems to retain good details up to 1600 and perhaps 2500. For a $300USD budget, are there better choices than the EPL5?
