Hi all- I bought a GF2 with 14-42mm last week for $339. The same shop now has a deal on the EP2 with 17mm and EVF2 for $530. I am within the exchange period so that is a non-factor. I was planning on getting a pancake lens for the GF2 anyway - and now that I see I can get the viewfinder with the EP2 and pancake for less total cost than adding just a pancake to the GF2, I am seriously considering that option instead. My concern is really about the AF speed difference between the two camera bodies. What would you guys do?
