Camera Lens Calibration Service Across the USA
Precision calibration for broadcast, ENG, and cine lenses — back focus, flange focal distance, zoom tracking, and MTF testing. Restore your lenses to factory optical performance.
Why Camera Lens Calibration Matters
Even a high-quality broadcast or cinema lens gradually drifts out of calibration. Impact, temperature cycles, heavy use, and mount changes all introduce small but meaningful shifts in optical alignment. The result — soft images, focus that doesn’t hold through the zoom range, or back focus that drifts in the field — can be invisible to the eye until it shows up on a monitor or in post-production.
Our camera lens calibration service uses manufacturer-specified test equipment — including collimators, resolution charts, and MTF analysis — to set precise alignment values and document the results. Every calibration comes with a written report so you have a performance baseline on record.
Canon Broadcast Lenses We Repair
We service all Canon ENG, EFP, and Cine Servo broadcast lens models.
HJ Series ENG
Canon’s core ENG lens range for shoulder-mount cameras. Common repairs: back focus, IS fault, focus ring, servo motor, and moisture damage.
KJ Series EFP
Mid-range Canon EFP zooms for sports and event production. Common repairs: zoom tracking, servo overhaul, IS calibration, and zoom demand.
CJ Series Field Zoom
Large Canon field zoom lenses. Full CLA, servo systems, optical calibration, and IS overhaul for large-format field production lenses.
Cine Servo Lenses
Canon Cine Servo 17-200mm and 50-1000mm. Servo motor, zoom and focus mechanism, optical calibration, and full cine lens CLA.
Legacy Canon ENG/EFP
Older Canon broadcast lenses still in field use. We hold parts for many discontinued Canon lens models — contact us with your specific model.
Canon EF Cine Lenses
CN-E cinema prime and zoom repair — focus, iris, zoom mechanism, and optical calibration.
Canon Broadcast Lens Faults We Fix
Back Focus Drift
Soft focus at telephoto or inconsistent zoom tracking. We reset flange focal distance to factory specification.
Image Stabilizer (IS) Fault
Ineffective or erratic IS, IS error messages, or IS lockup. Specialist Canon IS repair and recalibration.
Servo Motor Failure
Unresponsive or erratic focus and zoom servo on Canon lenses. Motor replacement and servo recalibration.
Zoom Demand Fault
Erratic or non-responsive Canon zoom demand controller. Potentiometer replacement and demand recalibration.
Moisture Damage
Canon lenses damaged by rain, condensation, or salt spray. Full teardown and clean-room restoration.
Focus Ring Binding
Stiff or notchy Canon focus ring — re-lubricated with approved compounds for smooth, precise manual focus.
