We clean Sensors for $30 and have a 30 day guarantee where we will redo the cleaning if any dust appears within 30 days.
Lens calibration can be done on most mid to high level SLR cameras. We calibrate the first lens for $30 and each additional lens at the same time for $15. Most calibrations are done in 1 day but some weekends and staffing can make it take as many as 3 days.
Note some cameras mostly entry level DSLR’s do not calibrate lenses.
