I've had my EP2 since Christmas. I like it a lot except for two things - a slow AF and no built-in flash. I picked up an used GF1 body only last week, because I was enamored with the idea of having a faster AF and a built-in flash. Now that I have both the EP2 and GF1, I am pondering if it's worthwhile to keep both cameras. Both cameras have their pros and cons. I noticed that there are a lot of people who own both the GF1 and EP1/2. What are the reasons that you own both cameras? Do you use both of them, and if so, do you use them differently? Or is one retired since you purchased the other one? BTW, this isn't a thread about GF1 vs. EP1/2. I am merely trying to determine if I should keep both cameras by figuring out if there are advantages of having two m4/3 cameras. Thanks for the help!
