david_haynes Posted July 7, 2003 Share Posted July 7, 2003 I now have the 10D and I'm selling my D30. I have decided to keep the double battery charger that came with the D30 because I often simultaneously use my G2 (and later will use G5) with the DSLR and it makes recharging more convenient. So I'm going to substitute the single battery charger for the original one that came with the D30 kit. One buyer was concerned about how to clean the sensor without the AC adapter. The double charger accomodates and comes with an AC adapter while the single one does not. The 10D will allow the user to enter the sensor clean mode with a battery installed, but the D30 will not unless the AC adapter is attached. Fortunately, I have never had to clean the sensor on the D30, but I've been told or read somewhere that an easy work-around is to use a freshly charged battery and simply use "B" setting on manual mode with a locking cable release to open the shutter, thus gaining access to the sensor for cleaning. I've done up to 4-minute timed exposures at night with my D30 and never had it try to close during exposure on "B" even with a dozen or more of these long exposures, and this was on a sub-freezing night in January photographing by moonlight. I'm wondering if there is any down side to cleaning the sensor in this way vs. the AC adapter and "sensor clean" mode found in the camera menus. The only thing I could imagine that could cause harm (other than an unexpected closing of the shutter) would be some sort of sensor overload from the abundant light without a lens attached. But I wouldn't think that would harm the sensor, since there are often blown out pixels from overexposure often as in light sky areas, too strong flash settings, etc. with no apparent ill effects. Has anyone tried this method to clean/access the sensor? And if so, any advice, precautions? Thanks Link to comment Share on other sites More sharing options...
