FAQs (Frequently Asked Questions)

When I point an all-in-one zoom lens (18-270mm, 28-300mm etc.) downwards, the lens barrel extends. What should I do?: The structure of all-in-one zoom lenses with significant telescopic motion is such that zoom creep is unavoidable during their use. We recommend that you use the zoom lock switch.
