I use my camera almost exclusively for photometry so it doesn't worry me.
It occurs when there is a bright star (mag 6 or brighter) in the field and the exposure time is longer than about 1 min. An example would be imaging eta carina where there a lots of bright stars. For imaging galaxies it would almost never be a problem. Exposures of up to 10 mins may allow a mag 11 star (depending on the filter) to saturate but this will also occur with a ABG camera. It has to massively over saturate before blooming occurs. The result is you lose the colour data for that star but the dimmer parts of the image will have better S/N.
