Helix Camera & Video provides Sensor Cleaning services for interchangeable lens cameras and camcorders.
If you are seeing black spots in your images it is likely due to dust on your sensor and requires cleaning.
Turn around time for sensor cleaning is usually 24-48 hours. Be sure to bring a fully charged battery.
Sensor cleaning is $60.
Note: If you are seeing black spots in the viewfinder on a DSLR that is dust in the prism not on the sensor. Sensor cleaning will not remove dust from the prism.
