The TTArtisan 11mm f/2.8 is a noteworthy addition to the realm of ultra-wide-angle lenses, particularly designed for the Leica L mount. This lens has surged in popularity among landscape, architecture, and interior photographers due to its intriguing combination of compactness, impressive optical performance, and affordability.
The build quality of the TTArtisan 11mm f/2.8 is impressive given its price. It features a robust metal housing that feels solid in the hand, with a sleek matte finish that both minimizes flare and enhances grip. Despite being a wide-angle lens, it's relatively compact and lightweight, making it suitable for travel and hiking. The aperture ring has distinct, clicky stops, which allows for easy adjustments, though some users may find that the lack of a focus ring might take some getting used to.
When it comes to optical performance, the TTArtisan 11mm f/2.8 does not disappoint. The lens provides excellent sharpness across the frame, with very minimal distortion and chromatic aberration, which is impressive for such a wide focal length. Even at maximum aperture, it generates good contrast and clarity, although stopping down to around f/4 or f/5.6 will yield the sharpest results, particularly in the corners. Bokeh can be somewhat busy due to the ultra-wide nature, but it’s not meant for portraiture anyway.
While the TTArtisan 11mm f/2.8 is straightforward to use, it does present some challenges typical of ultra-wide-angle lenses. The depth of field is extremely forgiving, which can be both an advantage and a hindrance depending on your shooting style. It can be challenging to compose shots without a viewfinder or if you're accustomed to longer focal lengths, but with practice, it can become a powerful tool in your photography arsenal.
Overall, the TTArtisan 11mm f/2.8 for the Leica L mount proves to be a stellar choice for those who require a reliable ultra-wide-angle lens without breaking the bank. Its combination of affordability, solid build, and optical performance makes it an attractive option for both amateurs and professionals alike. While it may have its quirks, the benefits greatly outweigh the drawbacks, making it worthy of consideration for your next lens purchase.
