I dont think its dust...

post #1 of 26
Thread Starter 
For the past week this white dot has been appearing in all my shots in the same spot.

example;



I've checked/cleaned the lenses but it's still shows up. I checked the inside on the mirror there are a few dust particles. I'm wondering if its safe to use a lenspen brush inside?

It looks like you actually have a dead pixel on your sensor.

I didn't know the sensor can get a dead pixel. damnit the camera is barely two months old.

Well the sensor is the same idea as an LCD, it has pixels and it senses light. So it is totally possible.

Some cameras can be set up to take a reference photo for the purpose of mapping out hot pixels. Possibly yours could? Otherwise warranty time.

EXIF data is stripped. What's the shutter speed on this photo? "Hot" pixels are sometimes an issue with long exposure times.

If it's a short exposure you've right there though, I'd definitely get that camera checked out if it's under warranty.

The mirror only redirects light into the pentaprism for the viewfinder. It can be shattered, and you'd still take nice crisp photos.

It's definitely a pixel problem, as it seems to be exactly 1x1, if it were dust, than it'd be a splotch.

Well I found why you didn't have that many replies; you posted in the wrong section

That sensor of yours doesn't look like it has dead pixels to me (could be wrong; my laptop screen isn't the most accurate), but if it's white spots you're talking about it could just be dust on the sensor itself. Taking a sensor wand to your sensor is a quick, <1 min maintenance step that I think should fix that. If you don't feel comfortable doing so, it's just as easy to hand your camera over to the store you bought it from or any friends of yours who are experienced photographers.

I saw the ninja edit to your post after I posted mine Yea, that looks like a dying sensor then. I'd get that fixed if it's still under warranty. If not, off the top of my head I think it was $100-$200 to repair a sensor? Personally I'd just live with the pixels. Unless you're a big time pixel peeper, it's not that big of a deal IMO. Annoying and probably makes OCD people grind their teeth, yes, but most people who are going to view your photos aren't going to do so at the max 12.1MP resolution anyways.
