| 1. First Look & Basic Clean |
We power down and unplug your lens, check the outside for any dings or cracks, and blow off dust from the body with clean air. We won't crack it open for inside dust unless it's in our cleanroom. |
Microfiber wipes, canned air, lens brushes. No harsh chemicals on those special coatings. |
Surface dust buildup, light condensation spots. |
| Outer Mechanics Test |
We spin the zoom and focus rings to feel for smoothness—no crunching allowed. If they're gunked up, we apply approved lube. We also inspect the mount for warps or bends. |
Precision torque drivers, pro-grade grease (fluorocarbon type). We stick to 0.5-1.0 Nm on screws. |
Stuck controls from dirt, sand, or salt exposure. |
| Getting to the Glass |
If the picture's still fuzzy, we pop off the caps and unscrew the front guard (usually 4-6 screws on box lenses). We wipe elements with pro cleaner and realign 'em on our collimator setup. |
Lens-safe tissues, high-purity isopropyl (90%+), collimator tools. All in a dust-controlled zone. |
Mold spots, fungus growth, water marks. |
| Impact damage |
accidents happen. Even the most ergonomically designed cameras matched with confident camera operators can still suffer unfortunate mishaps. While dropping a lens may not display any superficial damage to a lens glass or body, its delicate internals may be damaged. In the absence of any scratches, dents or scrapes, there will be some noticeable issue(s) if your lens has sustained damage |
Whether that is a new and unfamiliar sound, apathetic body movement or distorted image quality, manifestation will take place in one of these areas.While a thin knife or needle nose pliers may help you position bent lens rings into a manageable working position, you may be causing more damage to delicate metal or circuits than it’s worth. |
we suggest you bring it in for camera impact service. |
| Electronics & Servo Check |
We hook it up to a controller like Fujinon's ERD-10A and run diagnostics through the FIND system to spot encoder glitches. Bad boards get swapped out. |
Digital multimeters, scopes, Fujinon diag software. |
Slow servos, glitchy encoders from water damage. |
| Stabilizer Tune-Up |
We shake-test the OIS on our rigs and recalibrate with factory software for perfect pitch and yaw balance. |
Vibe tables, official calibration programs. This one's factory-spec only. |
Shaky footage from bumps or wind, alignment shifts after drops. |
| Put It Back Together & Bench Test |
We reassemble everything backward, tightening screws just right. Then full tests: zoom through the range, iris checks, bokeh smoothness, and 4K sharpness on our projectors. |
Test projectors, 4K charts. We watch for any focus breathing issues. |
General performance; we aim to keep it within 1% of original specs. |
| Seal It Up Good |
If the old coatings are shot, we add fresh anti-fog layers and seal with silicone gaskets around the housings. |
UV sealants for curing. |
Stopping future moisture leaks. |
