Stumbled across this on flickr:

I got my first D700 just under 2 weeks ago and the first night I was using it (taking photos of the cat) I noticed from ISO800 and up there was a white dot on the bottom 1/3rd of the images. I returned it and got a replacement last week. It was a lot better but I didnt have time to test it before heading out to shoot in a club where I found out it had a red hot pixel in the middle of the image apparent at ISO1600 and above - so I've got a red dot embedded in my 400 nightclub JPGs to fix.

See :

I returned this one and today received my third D700. I checked the serial on this one and its about 70,000 over the number of the last one (didnt think to write down the first serial number as I thought it was a fluke). This latest delivery shows a faint red dot at ISO1600 which becomes very apparent at 3200 :

Thats a crop from the top left, at least its not in the middle of the shot.

Another poster mentioned they had it on one camera, got it replaced and now it's not an issue. That indicates a manufacturing/QC issue surely?
 
moving :)
 
Hmmm. One bad pixel and 12,052,991 good ones. If that's a QC issue, then I think your standards are probably a little more stringent than most people's. Most people woud be happy with 99.99999%.

Also, remember, that one hot pixel would measure about 0.08mm on a print measuring 36cm x 24cm. How big an issue is that, really?
 
Cant you get it mapped out?? surley that would be the answer... I think that is the right term for sorting out the Hot pixel... I am sure some one else will correct me if I am wrong.

Strathycruise?......been featured on Barryboys many a time.............:D
 
What struck me after looking at these images wasn't really the hot pixel (though it is indicative of very poor QA, it can be mapped out) but was the high amount of noise apparent in the images.

I have seen some awesome shots at ISO3200 from the D3 and D700, and if these are at ISO1600 I'd say there was something more than the 'single hot pixel' issue wrong with your camera. I have seen less noise on a P&S! they are awfully noisy.

My Canon 5D manual warns about the odd hot pixel on the LCD screen being normal, but IMO, hot pixels on the CCD are completely unacceptable.

A large proportion of the cost of the camera goes into making the CCD. You are entitled to expect a fault-free image, noise concerns aside.

Indeed. You Pay that kind of money for the best - why expect these dots to appear? Especially when others do not suffer from them.

Didn't notice that, but yes, they are rather noisy!

What number would you say it becomes an issue? 10? 100? 1000?

I agree with the other posters - if it was a P&S, it's one thing but a high cost specialist piece of kit like this, the sensor should be perfect. If it's not, it should be replaced for one that is.

IMO.
 
I've have a hot pixel on my canon 1d mk11n. which started at iso 800 and above, and sometimes shows at 400. It does notice when printed as I failed to see it before I sent of a batch of pictures.
I also thought those shots where noisy, so something is going wrong somewhere. It's also quite large for 1 pixel, if we can see it on a 800x600 shot.
