I'm looking to upgrade my EPL1 and wondering whether to go for the EPL5 or EP5. One of the things which I'd like to see improvements in is the ability to take shallow dof photos in brighter light. For example, I'd like to be able to take something like P3251463 | Flickr - Photo Sharing! without blowing out details. Would the EP5 be noticeably better with its even faster shutter speed and iso 100? Or should I just save some money and buy the EPL5 and some filters?
