Redmi Note 9 to Sony A-Mount Camera Lens Adapter Case

Transform your Redmi Note 9 into a massive optical zoom camera by adapting it to accept Sony A-Mount lenses (like those from the Sony A57).

Because of the phone's sensor size, this setup gives any attached lens 5.4x more zoom. For example, a standard 300mm lens will be equal to 1620mm (around 70x optical zoom). It is incredibly powerful and perfectly capable of capturing highly detailed astrophotography, like craters on the moon.

🚨 IMPORTANT WARNING - READ BEFORE PRINTING 🚨

To make this Sony A-mount work, you must physically remove the built-in factory camera lens from your Redmi Note 9. Make sure you are comfortable with this advanced hardware modification before you spend the time and filament printing these parts. Proceed at your own risk.

Dimensional Accuracy: Do not alter the scale of the print. The extension tube is modeled to an exact length to replicate the standard A-mount system. It holds the back of the lens at the precise distance away from the phone's bare sensor so the optics work and the camera can actually focus properly.

This Thing used 2 3d models from other creators to make this possible although the models are almost completely changed to make them work.
