Prevention Against Sensor Dust

In a word – prevent.

Simply put, cleaning those sensitive sensors will always be both costly and time-consuming, not to mention running the risk of scratching it while performing the task.

I have lately been adopting the following techniques to greatly reduce this unavoidable problem, and it seems to be working

  • Use only prime lens (ie. fixed focal length glass) whenever possible. I find all my three 50mm lens perfect in most scenario.
  • Point your zoom lens downward when retracting the lens barrel slowly
  • Lock your lens (applicable for lens like Nikkor 28-300mm VR or Nikkor 18-300mm VR) to prevent lens creep which indirectly increases the frequency to retract your lens
  • Acquire lens that do not extend or retract with zooming (ie. Nikkor 70-200mm F/4 VR III)
  • Change lens only in your hotel or home, never in an outdoor environment
  • Get your pro glass regularly serviced to replace ass rubber gasket and seal every 3 years
