I'm using this LVF1E on a LX5 camera, and it is even more useful on this than the GF1. This is because LX5 users are less likely to want the eye level manual focus facility, and this is the only area where the LVF1E does not score maximum points, as the resolution is lower than the camera screen. Otherwise, this is a must have accessory as far as I am concerned. Expensive...yes, but it's beautifully made, (in Japan), gives a large, clear and bright eye level image, with full information, is easily switched from LVF to camera screen, and above all enables the world's best compact camera to be used at eye level, opting out of the 'arm's length' brigade. Wonderful!
