I'm coming out of a D80, and have many friends with Canons that I've compared this issue with as well (30D, 40D, XSi, XTi, XT). I have better ISO performance, but I have to use slower shutter speeds and/or more ISO with a set amount of light than any of the other cameras. Example: It's nearing dusk. All the other cameras are dialed in around 1/80 sec, ISO 200 to shoot at f/4 and exposure correctly. The D300 would need to drastically lengthen the shutter speed and/or increase the ISO for the same exposure at f/4. And by drastic I do mean drastic. Shots I could handhold at f/4 ISO 200 on my D80 or my Canon buddies shoot, I can't handhold with my D300 in the same conditions without jacking the ISO up to 1600 to keep shutter speeds equal. Real problem or is this just a D300 issue? If it's a real issue, how do I go about getting this corrected? I've never had to send anything in for warranty work before (I bought it from an authorized dealer online, Beach Camera). Also, while I've got you guys in here, I can't open my RAW files from my D300 in Photoshop CS2 (I'm on the lower of the two qualities for RAW files, 12 bit). Keeps saying the format isn't recognized or valid or something like that. Major pain. Any fixes?
