Versatility and Use Cases
The Canon RF100-400mm is designed for specific use cases such as wildlife and sports photography due to its extensive zoom range. The lens excels in situations where capturing fast-moving subjects from a distance is crucial. Its ability to accept RF tele extenders also extends its reach, enhancing its versatility further.

Its compact size and lightweight design make it perfect for travel and casual shooting, allowing photographers to maintain mobility without sacrificing quality.
Image Stabilization Capabilities
One of the standout features of the Canon RF100-400mm is its Optical Image Stabilizer, which provides up to 5.5 stops of shake correction, and up to 6 stops when paired with compatible EOS R series cameras. This technology is crucial for maintaining sharpness in images, especially when shooting at longer focal lengths or in low-light conditions. The TTArtisan AF 27mm, while lacking in optical stabilization technology, makes up for it with its close focusing ability and a large aperture of F2.8, providing a different set of advantages that can yield beautiful bokeh effects in images.

The TTArtisan AF 27mm also offers impressive autofocus capabilities, featuring an STM stepping motor for smooth focus transitions and eye-detection AF for precise subject tracking. While both lenses excel in autofocus, the Canon lens is better suited for high-action scenarios, while the TTArtisan lens shines in portrait and detail-oriented photography.
