Dead pixel or dirt?

rubdub

Hey guys,

I've noticed these pink dots (see attached) on my images recently. I'm shooting on a Canon 5d mkIII.

Just wondering if anyone has ever had anything like this before?

Wondering if it's a dead pixel, hoping it's dirt.

Thanks.

Don’t think it’s dust...

i would guess dirt or dust would block light getting to the sensor, rather than causing a spike.

Looks like a problem with the image sensor or the connections to it.
You could try cleaning the sensor, but it doesn't look hopeful.
Maybe it's something translucent on the sensor causing a prism effect, most of which gets directed away from the sensor.
If it only happens with one lens, maybe it's a defect in a lens.
Good luck with it!

Hmmm... haven't tried it recently with a different lens.. thanks for the idea

Still not hugely hopeful, but fingers crossed..

How many actual pixels is it taking up?

It looks like a block of Red pixels are hot (turned on all the time) It could be a sensor or software fault. An authorised repair centre could analyse it.
