The patent describes a compact optical system engineered to provide superior optical performance, addressing challenges commonly associated with small form-factor lenses.
Background
In imaging devices, there is a growing demand for lenses that balance compactness with exceptional optical quality, ensuring sharpness from the center to the periphery of the frame. However, conventional designs, such as those outlined in prior patents, often suffer from optical aberrations, including pincushion distortion, leading to reduced performance at the edges of the image. This new optical system seeks to overcome these limitations by offering a refined design that enhances image quality across the entire frame.
With this development, Canon appears to be pushing the boundaries of lens miniaturization while maintaining high standards of optical performance, potentially expanding creative possibilities for photographers and videographers alike.
