Hot pixels : should I ask for a new camera?

[Mad Aussie]

Hot pixels? We are talking about the LCD right?

If so, then they are probably right in saying most will this issue. Monitors are often the same. However, if it's under warranty I'd take it in and at least ask the question.

The camera is brand new, just couple of months old, so is still under warranty. I don't know how long will take at service to send me back fixed, or a new one.

MA : I'm talking about hot pixels (dead pixels) on sensor.
When I'm taking some shots with long exposure in the dark, on every image, I see 5 pixels (blue, red, yellow or even white) in the same place, same colors every single time.

So... five pixels isn't too much for a brand new camera?

I'm no good to you then because I've never heard of this. And after owning several DSLR's have never noticed it if it existed on my cameras.
I'd be going back to the shop and bitching like a teenager when the power goes out for 5 mins!!!

It's an issue that can (but not necessarily will) rear its ugly head with all makes and models when shooting long exposures. The general consensus is that it is a heat issue and will only get worse over time. Makes me wonder what the effects of shooting live video has on the sensors and for that reason, I've never placed my D90 0r D300S in video mode.

I don't know. I never tried video in low light, but I'm guessing that is not that visible as in pictures.
I'm sending my camera for service, hoping that will not take more than a month.

I wasn't really talking about "low light video". I guess what I was trying to illustrate is that video usually involves the capture of several minutes of footage and that makes it much like long exposure photography in that the sensor is subject to heat build-up.

Not something I can prove, mind you, but that's my story and I'm sticking to it.

All sensors have a small number of dead pixels its a fact not a fault. Will generally only show as described in long night exposures. I have seen the same on my 1D series cameras.

What makes them visible
First of all they are tiny, for that reason they are not visible enough most of the time
High f values (narrowed aperture) (F 20)
High ISOs (ISO 1600)
Low-Light environment, night etc. (They are visible especially on darker backgrounds)
Long Exposure Times (30 sec.)

Live with them and if necessary edit them out in PS...
