Maintenance Tips

• Keep Front/Rear Glass Clean: Use a blower first, then a microfiber cloth; avoid rubbing dust across L-series coating.
• Use Lens Hood Always: Essential for protection against flare, impact, and stray dust.
• Protect IS System: Turn off Image Stabilization when mounted on a tripod to reduce internal wear.
• Smooth Zoom Usage: Extend/zoom gently—avoid forcing the barrel, especially in cold conditions.

• Contact Care: Clean electronic contacts lightly for reliable autofocus and IS performance.
• Filter Protection: Use a high-quality UV/protective filter to safeguard the front element.
• Mount Safety: Avoid strain on the lens mount when using heavy rigs or long shooting sessions.
• Proper Storage: Keep capped, upright, and padded away from heat and humidity.
