I did some 30 second exposure, tantamount to bulb. I noticed a handful of really red pixels across all the images. The longer the exposure, the redder they are. So if I ever do important long exposure, such as at night/sky, there will apparently be a whole new solar system of red stars in all my images. Anybody else know about this? I was using an LED keychain with blue tint light in a blacked out room to paint light onto a variety of items to bring them into the picture. I do not think it could be anything but over sensitive pixels. The camera was moved about, the red pixels are precisely in the same position each time.
