FrameLineView Pro

It uses micro-optics and adjustable brightness to overlay precise composition guides without obstructing the view, making rangefinder cameras fully accessible to eyeglass users.

Key Features

Adjustable frame line projection for 28mm and other focal lengths
Micro-optics system that integrates with existing viewfinders
Brightness and contrast controls for different lighting conditions
Battery-powered with USB-C charging and long battery life

Target Users: Professional and enthusiast photographers who wear glasses and use rangefinder cameras like Leica M-series

Revenue Model: $199 one-time hardware purchase with optional $9.99/mo subscription for advanced features like custom frame line shapes and cloud sync
