The Canon lens excels in producing high-quality images with stunning bokeh and exceptional low-light performance, while the TTArtisan lens offers a unique perspective with its wide-angle and fisheye capabilities.

Design and Build Quality

The Canon RF45mm F1.2 STM boasts a compact design due to its large-diameter mount and short back focus, which also allows for effective digital distortion correction. This lens is designed for creators who seek a balance of quality and portability. On the other hand, the TTArtisan 7.5mm F2.0 features a simple yet effective design that prioritizes ease of use, making it suitable for everyday shooting scenarios.

Optical Performance

When it comes to optical performance, the Canon RF45mm F1.2 STM shines with its f/1.2 aperture, which significantly enhances its ability to shoot in low-light environments. This large aperture also allows for faster shutter speeds and creates a beautiful three-dimensional look to images through its excellent bokeh quality. In contrast, the TTArtisan 7.5mm F2.0, with its maximum aperture of f/2.0, offers decent low-light capabilities but does not match the performance of the Canon lens. However, its unique fisheye perspective allows for creative compositions that the Canon lens cannot achieve.
