Verdict
Pick the Irix 11mm if you need an ultra-wide perspective for landscapes, architecture, or tight interiors and can work with the slower f/4 aperture. Choose the Sigma 30mm if you prioritize low-light performance, subject isolation, or a standard prime with a fast f/1.4 aperture—its higher price buys a brighter lens and a more versatile focal length for general use. The Irix stays the better choice if budget is tight or ultra-wide coverage is non-negotiable.
