I got this D300 a bit over a week ago, and have been slowly exploring it's functions and how it produces images as compared to my older D50. I was playing around with some high ISO settings, and just took some shots around my office. These weren't anything I'd really offload to my computer, so I was zooming in fairly closely on the camera LCD screen (really good, BTW) and suddenly this "gleam" in the blackness of the old minolta in the photo attracted my attention. I zoomed in on it, and on the LCD screen it became clear it wasn't a specular highlight, but was a small cluster of pixels displaying white or some combination of colors that looked white on screen.
I started looking around at other shots, and took a few exposures in total darkness on manual (lens cap on) to see what else showed up. I saw three "hot" spots, so I began going back and looking closer at previous images, and wherever there was dark, I could find them - but they plainly were more visible at ISO 400 and higher, much less noticeable at ISO 200.
I downloaded the shots to my laptop to see if they showed up in the downloads - and the results I've posted here. The first shot is a tight crop of a small portion of the original image, shown also. The three areas I'm talking about should be visible in the lower left and upper right sections of the cropped image.
To be honest, they really don't show up unless I'm practically pixel-peeping, but they are obviously stuck or dead pixels, or whatever they're called with sensors.
The question to all of you is: What would you do? I might be able to exchange the body (if they have another one, and would do this) or have it sent to Nikon for warranty repair. It might be hard to demonstrate what's wrong without some sample images being sent with the camera. Also, I don't know if this is considered enough of a defect for them to "fix" and may be something common on higher density sensors. I just don't know. But, my little old 6.1 MP D50 has been, and remains flawless in this regard.
Here are the images shot at ISO 3200
Cropped version - should be able to see the three "hot" areas.
Original (non-cropped) version.
Am I making a big deal out of nothing? I'm a bit on the fence here... so thanks for some reasoned opinions. -phil
