Thanks for your attencion. It all boils down to an advice somebody gave ages ago to a newcomer who asked him about getting a camera giving him good result. Get whatever camera that`s not damaged, especially the lens, get a good tripod, put the camera on it, stop the lens to f:8-11, use low iso, figure exposure at very low light, dusk, twilight,night and you`ll be there to start with. Apropos night exposure, reminds me the timer hungarian photograph Brassai used for his night exposures- just the time it takes to smoke a cigarette. Now with the wonders of Sony 7s or Olympus stabilisation one can do wonders but still not in the 5-10sec region. And to get best edge sharpness with GH-3 I had to stop the lens to at least f:5.6.
