Just got an Olympus OM-D and I am happy with my early experiences with the camera's kit lens after converting from the Sony NEX system. I ordered the Panasonic 20mm pancake shortly after getting the camera based upon on-line reviews and the fact that it is a nice compromise between 35mm and 50mm (on FF equivalent). Although I haven't had a chance to really use it, after mounting it and playing with it for a bit, I am wondering if it may be too small?!?! Can't believe I am saying that, but has anyone else had those thoughts? I think it is going to take some getting used to, and I wonder if the Panasonic 25mm may have been a better choice. I am going to get out and shoot with it for a while tomorrow and see if it grows on me.
