Laowa Cine Prime 3 Lens Set - 7.5mm, 10mm, 17mm

No, the Laowa Cine Prime lenses are manual focus only. They are designed for precise manual control preferred in filmmaking.

A 'T' stop (Transmission stop) measures the actual amount of light transmitted through the lens, which is more accurate for video exposure than an 'F' stop (which is a theoretical value).

No, these lenses are specifically designed for the Micro Four Thirds sensor size. They will not cover a full-frame sensor, and using them on such a camera would result in significant cropping or severe vignetting.

The 0.8 MOD gears are a standard size used in professional cinema accessories, allowing the focus and iris rings to be easily controlled by external follow focus systems, motor drives, or other rig components.

Use a soft, lint-free lens cloth. For tougher spots, apply a dedicated lens cleaning solution to the cloth (never directly to the lens) and gently wipe.

Warranty information is typically provided by the retailer or manufacturer. Please refer to your purchase documentation or the Laowa website for specific warranty details.

No, these lenses do not have built-in optical image stabilization. Stabilization would need to be provided by the camera body (if it has in-body stabilization) or through post-production software.

Ensure the camera body is clean and free of debris. Align the mounting indicators precisely and rotate firmly until it clicks. If resistance is met, do not force it; check for obstructions.

This is a manual focus lens. Ensure the focus ring is set correctly for your desired subject distance. Check that the aperture (iris) is set to the desired T-stop. Verify focus through the camera's viewfinder or live view.

Some vignetting may occur at wide apertures (low T-numbers) or with ultra-wide lenses like the 7.5mm. This is normal and can often be corrected in post-production. Stopping down the aperture (increasing the T-number) will usually reduce or eliminate vignetting.

Ensure there is no debris caught in the gears. If stiffness persists, it may require professional servicing. Avoid excessive force, which can damage the gears.
