Sensor cleaning – My experience

After my recent trip to South Africa, my Konica Minolta Dynax 7D digital SLR camera had a significant problem with dust on the sensor (5 or 6 spots very visible on clear skies or plain surfaces). I decided to go for the Sensor Swabs from Photographic Solutions Inc.

All in all, this is a very efficient solution. However, a few things must be kept in mind (like is noticed by all users according to what appears in digital photo forums):

  • Never re-use a Sensor Swab (after the 2-pass operation, it would not bring positive cleaning, but just more junk on the sensor)
  • Don’t over fill it with cleaning solution (a few drops on the part far from the end of the Swab will creep by capilarity; Too much of it leads to catastrophic -but easy to correct- results)
  • Press firmly (but not too much, this is a sensitive device)
  • If it does not work perfectly the first time, it’s OK to try again after a few seconds

Au total, pour mon premier essai (et pour confirmer ces règles), j’ai dû utiliser 4 Sensor Swab.
