i went shooting a skateboard event today, but halfway i noticed that all of my shots had a red dot in the middle and a line accompanied with them. it seems to be better visible at higher iso's like 1600, but its also there at 200
it also showed up in some test shots i did a minute ago.

what is it and how can i fix it??!! i never had this before, it just happened today. didnt do anything weird with the cam.

here's a shot where it is very obvious.

Can you post another one using different settings we can see?

I am afraid it looks like a faulty CCD and will need to be sent to Nikon for repair.

Wow,

It sure looks like a Lazar pointer was aimed at the car as the photo was taken.

Other then that, I would think it was a bad CCD.

A cracked CCD was my first thought. But, a CCD surface defect should only show up at smaller apertures. The electronics may be impacted causing it though.

That the very fast shutter speed was a contributing factor was my next thought (sometimes you can get some strange symptoms at ununusually fast shutter speeds and that was was taken at around 1/2500 second). So, I'm wondering if the problem occurs at slower shutter speeds.

I also wanted to see another photo to make sure it's in the same place with the same symptoms (it looks a bit like some kind of odd flare).

Chances are, it is a defective CCD.

thanks for the replies guys,

its in every photo i have taken after this one, including this one:





here's another one


yes thats one angry cop hehe

i have the problem at all shutterspeeds and iso's, but at lower iso's its less obvious. and i asked Nikon support, but they said it wasn't a color hang of a pixel and told me to send it to them. but after reading the stories about camera's that are gone for 3 months i'm first trying to fix it with the help i get here

My eyes are not what they used to be (and/or I need a better monitor). But, I can't even see it in the smaller image. I can see in the larger image you took at a higher ISO speed.

But, even if it's more visible at higher ISO speeds, it shouldn't be doing it.

On the *very* slim chance that it's spec of something causing some kind of odd flare, I'd clean the lens and sensor. But, it looks like you've probably got a defective sensor to my eyes. So, your best bet is going to be sending it to Nikon for repair.

in the small image its in the bottom of the middle red triangle.
i even have it when i leave the lens cap on btw, and its less noticable at 1+ sec shutterspeeds.

if its not gone in a week i'll send it to Nikon, let's hope it doesnt take too long till i get it back

I'd clean the sensor, just on the slim chance it's some kind of real strange flair between the microlenses on the CCD, or perhaps even blooming along a line of photosites, caused by a spec of something on the AA filter

But, it's probably a bad sensor.

I noticed the same thing on my D50 when I first bought it a year ago. It stopped showing up after about 2 months.
