Freewell 1.55x Gold Anamorphic Lens with 17mm Mount

It means the lens captures a wider field of view horizontally than vertically, and when desqueezed, it stretches the image to create a 2.76:1 aspect ratio, wider than standard widescreen.

You need a smartphone case or rig with a 17mm threaded mount for attachment. For the full cinematic effect, you'll need an app like Blackmagic Camera or post-production software to 'desqueeze' the recorded footage.

Gold flares are created by light sources (like the sun or streetlights) hitting the lens at an angle. They are a characteristic visual effect of anamorphic lenses.

This lens is optimized for the main 1x camera on most smartphones. Using it on ultra-wide or telephoto lenses may result in heavy vignetting or poor image quality.

Use a soft microfiber lens cloth to gently wipe the lens elements. For stubborn smudges, lightly dampen the cloth with lens cleaning solution or distilled water.

Please refer to the manufacturer's documentation or the retailer's product page for specific warranty information, as warranty periods can vary.

Ensure you are using a compatible 17mm threaded smartphone case or rig. Check for any debris on the threads of both the lens and the mount.

Verify the lens is correctly aligned with the smartphone's main 1x camera. Vignetting may occur if the lens is not centered or if using a different camera lens than intended.

Ensure you are shooting with strong light sources to create flares. For bokeh, ensure there is sufficient distance between your subject and the background. Remember to desqueeze the footage for the full anamorphic effect.

This is expected. Use third-party apps like Blackmagic Camera or post-production software (e.g., Adobe Premiere Pro, DaVinci Resolve) that offer anamorphic desqueeze options to achieve the 2.76:1 aspect ratio.
