Need your help /p/

Do I have dead pixels or dust/crud on sensor or lens. The other block dots are obviously dust. See full pic.

That's a really dirty sensor, but I think those noted areas are dead pixels.

I also noticed a blue dead subpixel at the bottom-right corner of the first square if you divide the pic into 9:

Have it verified by someone else - iana(repair technician) - but i'd recommend getting a return if it's just a week.

I did some more shooting and it looks like they only show up on certain types of background.

Anyone tried Sensor Swabs?

He usually is, he says stupid stuff he probably thinks is wrong just to get noticed.

That particular page is good for n00bs looking to identify dead pixels, though.
