One of the main drawbacks I am now experiencing with my Nikon D70 is dirty sensor, little dark marks in the same position on every frame. I am now constantly cleaning with Eclipse E2 and swabs but do not know how much more cleaning the sensor can take. My theory is that as cameras age with regular use they produce more and more wear particles that land on the sensor. Does anyone know how often a sensor can be cleaned or has any camera manufacturer produced an efficient sensor cleansing mechanism or a sensor that can be cleaned regularly at home.
Kind Regards..David
