Tried that... didn't work.
Also, if you are shooting a street scene at night, even if OIS allow you to get the buildings reasonably sharp, the slow shutter speed will ensure that all the moving people will be blurred. If the 'ghost' effect is what is desired, then fine... if not :thumbsd:
With a F30 at ISO1600, the shutter speed might just be fast enough to avoid blurring the people too much. In other word, OIS is not really very effective at night.
If you guys have seen my comparison shots of F30 at ISO1600 and D-Lux2 at ISO400 and still feel that LX1/LX2 is good enough as an all-purpose camera, then I would say that the LX1/LX2 are for you.
