Hey everyone I'm a total photography rookie, but have realized that the built in flash in my olympus pen e-pl1 is simply not doing the trick. Primarily, I want the ability to take portraits and pictures at get-togethers, where the lighting in the room might not be optimal. So I'm looking for a add-on solution to my camera. I live in Denmark, so I'm looking to find an online retailer who can ship to Denmark, OR simply just to find a model or two I can look up locally. Can someone help? Would it be possible to find a flash that works with Canon EOS models as well, or are the sockets unique?
