Sensors get dirty and can cause annoying spots on your pictures. Dust and debris can penetrate your camera and that is why it is very important to have your sensor checked and cleaned on a regular basis. We have 3 full time on-site technicians that are specifically trained to perform sensor cleaning within 1 to 2 hours on digital SLR bodies and mirrorless bodies. The cleaning is performed per manufacturer recommendations and each sensor is checked using microscopes. We stand behind our sensor cleanings with a limited warranty as well.
