The DMW-LVF1E viewfinder for the Panasonic GF1 is expensive but extremely versatile. As expected, it allows photographers like me to hold the camera up to my eye. This may be a neccessary move in bright light when the screen would be almost unusable. However, it hinges through 90 degrees allowing you to hold the camera at low level without being a contortionist. This is extremely useful in close-ups of flowers etc. Finally, there is a switch on the viewfinder that allows easy switching between viewfinder and screen. If you have a GF1, then you should consider this as a potential accessory.
