Push the limits of your creative vision with the TTArtisan 11mm f/2.8 Ultra-Wide Lens for Sigma/Leica L-mount full-frame mirrorless cameras. This manual focus prime lens provides an ultra-wide 126° field of view — allowing you to capture broad landscapes, immersive interiors, dramatic architectural shots, and sweeping skies with minimal distortion.

Ideal for astrophotographers, architectural shooters, and cinematic visual storytellers, the bright f/2.8 aperture ensures strong low-light performance and lets you create shallow depth-of-field effects even at wide focal lengths. Whether you're shooting city lights, night skies, or wide natural scenes, this lens delivers exceptional clarity and contrast.

The manual focus mechanism is smooth and precise, empowering creators to thoughtfully compose and refine every frame. The advanced optical formula helps reduce chromatic aberrations and distortion, maintaining sharpness and true geometry from edge to edge — even on high-resolution sensors.

Built with a rugged, full-metal barrel, the TTArtisan 11mm f/2.8 offers a premium tactile feel and long-lasting durability. The integrated metal lens hood minimizes flaring and protects the front element, making it perfect for both studio work and outdoor shooting.

Compact yet powerful, this ultra-wide lens is an excellent addition to any Sigma/Leica L-mount setup, providing unique perspective and pro-level performance at a great value.
