davey h Posted April 27, 2008 Share Posted April 27, 2008 Hi to all hope you can help?. I have a d300 with different lenses all nikon 70-200 vr 2.8 standard 18-70 and sigma 10-20. Took some pictures the other day in apperture priority with 70-200 vr with image quality set to raw the camera reading was about 1200th aperture around 5.6. When i pressed the shutter release the camera sounded about a 30th of a second maybe slower. I took a few snaps all the same motion. The images came out over exposed i checked the +/- all ok. I then switched the image quality back to jpeg fine large and all ok pics turned out fine with same shutter speed. I then switched back to raw and old problem came back then back to jpeg and all ok again. Any help would be appreciated Thanks Link to comment Share on other sites More sharing options...
juan_parm_nides Posted April 27, 2008 Share Posted April 27, 2008 David, Have you updated your D300 firmware to latest version? Could be this fix the problem. Link to comment Share on other sites More sharing options...
davey h Posted April 27, 2008 Author Share Posted April 27, 2008 Yes i have all up to date. Havent heard of this before seems like the display and shutter speed are out of sink. Link to comment Share on other sites More sharing options...
Matt Laur Posted April 27, 2008 Share Posted April 27, 2008 Did you perhaps have the exposure delay behavior turned on? That might have given you the impression of a longer exposures, while actually just delaying the shutter opening after the mirror went up. Or... did you have exposure compensation dialed up?

davey h Posted April 27, 2008 Author Share Posted April 27, 2008 Hi the exposure compensation was fine Thanks but what is the exposure delay? Link to comment Share on other sites More sharing options...
davey h Posted April 27, 2008 Author Share Posted April 27, 2008 Hi found the exposure delay mode and all switched off looks like it,s going back again my second d300 body must be really unlucky Thanks. Link to comment Share on other sites More sharing options...
walterh Posted April 27, 2008 Share Posted April 27, 2008 Did you reset all to factory default ? It sounds like something is screwed up. The jpg image is obtained from an internal raw image that just is not written to the CF card. Why should the jpg be ok and the RAW not? Link to comment Share on other sites More sharing options...
joe_a2 Posted April 27, 2008 Share Posted April 27, 2008 I'd do a soft reset as Walter suggested, then I'd format the card in the camera again. Make sure you are in Single Shot mode (S), not Mirror Lock Up (MLU) on the dial. Keep us posted. Link to comment Share on other sites More sharing options...
raysgallery Posted April 27, 2008 Share Posted April 27, 2008 I don't know if this is your problem or not, but I had a problem close to this. I put one set of AA batters in the MB-D10 backwards. When I tried to shoot at 8 fps the D300 would only take 2 fps after that (only in the RAW setting). I didn't tell Teck support what I had done, but when I it back from them, they said that the only problem was that I had change the NEF (RAW) recording in the Shooting Menu from 12 bit to 14 bit which I hadn't done (the D300 only shoots 2 fps in 14 bit RAW). I guess putting the batters in the MB-D10 backwards did it. So check all of your Menu's out pretty good. Link to comment Share on other sites More sharing options...
davey h Posted April 28, 2008 Author Share Posted April 28, 2008 Big thanks to you all think Charles has hit it on the head (14 bit) I changed my raw setting back to 12 bit and seems ok Big thanks to you all and Charles. Link to comment Share on other sites More sharing options...
ShunCheung Posted April 28, 2008 Share Posted April 28, 2008 The 14-bit RAW mode on the D300 will introduce extra delay, for one thing more shutter lag. And using the MB-D10, even though you have 8AA or the EN-EL4(a) in it, the D300 drops from 8 frames/sec to 2.5 frames/sec. However, the 14-bit mode should not completely mess up your exposure. It is supposed to improve image quality. Link to comment Share on other sites More sharing options...
rarmstrong Posted April 28, 2008 Share Posted April 28, 2008 I shoot 14-bit RAW with my D300 all the time and have never had this happen. I guess I would reset the camera to it's factory defaults and do the firmware upgrade...if that doesn't fix the problem then I'd pack it up and send it back.
