What Nikon should do , to heat rid of the depth of field problem are: Change to a new LED , better lens f stop , at least 5.6 . They prefer a cool scan, low light, low energy ,no heat. Imacon and other scanner manufactures prefer a more intensive light source and a fan to stable the scanner heat inside. In the new Imacon they have build in a thermostat set at 20 Celsius , despite what conditions it is outside in the room. The Imacon scanner lens works at f stop 8 . Mr Hemmingway at Polaroid maybe can answer what is the lens f stop in a ss4000 scanner. Best regards Mikael Risedal
