I bought my Nikon D200 about 3 days ago, and have been snapping away for ages. Compare to the old Nikon FE it has some great features, such as autofocus, but one thing so far I really miss and that is my long exposure times and ludicrously flexible light metre. It just seems there is no way other than bulb mode to run the Nikon D200 for longer than 30 seconds. There doesn't appear to be a press to engage press to release option. So far the only workarounds I have found is either use a remote ($170US is out of my price range), or trigger via computer. The problem with the latter being that my laptop battery won't last long enough to take the 3h exposures I do for star shots (mind you no idea how CCD noise will affect this at this length). So other than spending money, dragging a laptop around, or holding my finger on the button till it turns blue hoping not to move the camera, is there any other method, or cheap product, or even do it yourself product that can trigger the shutter for longer than 30 seconds?
