Sainsonic Kamlan 50mm F 1 1 II Recensione | 54 Dati a confronto

This manual-focus prime lens for APS-C mirrorless cameras delivers remarkable value for its $249 price point, standing out with an ultra-fast f/1.1 aperture that produces incredibly creamy bokeh and excellent subject isolation. Optically, it defies its budget status by offering near-perfect lens element centering, minimal distortion, and exceptionally low vignetting—measuring roughly one stop or less in the extreme corners wide open. When stopped down to a "normal" range of f/4 to f/16, it transforms into a highly capable landscape tool with impressive corner-to-corner sharpness. Furthermore, the physical build is premium and robust, featuring a solid metal construction, beautifully damped control rings, and a de-clicked aperture ring that is highly beneficial for video shooters. However, achieving this low price and extreme aperture introduces several optical compromises, most notably soft corners and heavy longitudinal chromatic aberrations (color fringing) when shot between f/1.1 and f/2.8. It exhibits strong coma in the corners, messy sun stars at f/16, noticeable color shifting, and substantial flare when the sun is directly in the frame. From a handling perspective, the lens suffers from heavy focus breathing and...

The Kamlan 50mm f/1.1 II, dubbed the "New Bokeh Beast," is a manual-focus portrait lens designed for crop-sensor mirrorless systems, including Sony E, Fuji X, Canon EOS M, and Micro Four Thirds mounts. Priced affordably at around $229 / £180, this lens is highly praised for its exceptionally solid, well-engineered metal construction, precise and well-damped manual focus ring, and a de-clicked aperture ring that is highly useful for video recording. On crop sensors, its effective focal length behaves like a 75mm to 100mm portrait optic, allowing photographers to achieve a beautifully shallow, full-frame-like depth of field. Compared to its predecessor, it features an improved optical formula that replaces noisy "onion ring" bokeh with highly desirable, smooth "soap bubble" background blur, while maintaining incredibly well-controlled distortion and vignetting. Despite these creative strengths, the lens exhibits clear technical limitations in performance and handling. The primary pros of the lens are its ability to create gorgeous, "beastly" bokeh, its excellent all-metal build quality (including a metal hood), and its low price tag. Conversely, the cons include poor central sharpness when shooting wide open...

The DPReview forum post "Kamlan 50mm f1.1 MK2 - first impressions" highlights the user's initial experiences testing this ultra-fast manual focus lens, noting its robust, all-metal construction and pleasant, rounded bokeh. While center sharpness is soft wide open at f/1.1, it becomes very usable for portraiture and improves significantly when stopped down to f/1.4 or f/1.8. Conversely, the lens is heavy and large, potentially causing balance issues on smaller mirrorless bodies. Other cons include a stiff, inconsistent focus ring, a de-clicked aperture ring, noticeable chromatic aberration in high-contrast scenes, and an extremely thin depth of field that demands precise manual focusing.

The Kamlan 50mm f/1.1 Mark II is a budget-friendly, all-metal manual lens for APS-C and Micro Four Thirds cameras that provides a significant, high-character alternative to modern optics, noted for its creamy bokeh and strong center sharpness. Users highlight its excellent color, contrast, and smooth focus/aperture rings, representing a major upgrade over the first generation for portrait and artistic shooting. Key drawbacks include a heavy 600-gram design that can unbalance smaller camera bodies, along with prominent edge softness and purple fringing at wide apertures, particularly between f/1.1 and f/1.8. Additionally, the manual-only operation, combined with a clickless aperture ring, may present challenges, with optimal sharpness generally requiring stopping down to at least f/4. YouTube
