Laowa Ranger FF 16-30mm T2.9 Cine Lens

A parfocal lens maintains focus as you zoom in or out. This means your subject stays sharp throughout the zoom range, which is crucial for cinematic applications.

T2.9 refers to the actual amount of light transmitted through the lens. It's a more accurate measure for cinematographers than an F-stop, especially when comparing lenses from different manufacturers.

While it can be used for still photography, its primary design and features (like minimal focus breathing and parfocal zoom) are optimized for video production. It may be more complex to operate than a dedicated still photography lens.

This lens does not feature built-in image stabilization. Stabilization would typically be handled by the camera body or external support systems like gimbals or tripods.

Focus breathing is the change in the lens's field of view when you adjust the focus. This lens is designed to have virtually zero focus breathing, preventing the image from "zooming" slightly during focus pulls.

Yes, the 'FF' in the name stands for Full Frame, indicating it is designed to cover a full-frame sensor.

The minimum focusing distance is not specified in the provided product information, but typically cine zooms offer relatively close focusing capabilities.

Ensure the EF mount contacts on both the lens and camera are clean. Try re-mounting the lens. If using an adapter, check the adapter's compatibility and condition.

Confirm the lens is properly mounted and the focus ring is set correctly. Ensure the camera's internal focus settings are not interfering. Check for lens breathing if focus was adjusted during the shot; adjust focus carefully.

Avoid forcing the zoom mechanism. Ensure no external elements are obstructing the zoom ring. Contact support if the issue persists.
