Scoring Methodology

Wuseria scores lenses on a 0-100 scale for each photography genre. Scores are calculated from optical performance data, not marketing specs or subjective reviews. The goal is to answer: “How well does this lens perform for this specific genre?”

Each genre uses a weighted formula that emphasizes the optical qualities most important for that type of photography. For example, nightscape scoring heavily weights coma and wide-open corner sharpness, while portrait scoring emphasizes bokeh and center sharpness wide open.

Optical data comes from lab tests and detailed field reports by trusted review sources (LensTip, Optical Limits, DPReview). Each optical field (center sharpness, corner sharpness, coma, astigmatism, chromatic aberration, distortion, vignetting, bokeh, flare resistance) is rated on a 0-2 scale where 0 is poor, 1 is average, and 2 is excellent.

Lenses without sufficient optical data are shown as “Not yet scored” rather than estimated. We only score lenses when we have data from trusted sources. This means some newer or niche lenses may lack scores until reviews are published.

Genre scores are supplemented by editorial picks — lenses that the formula alone might not surface but that are widely recognized as exceptional for a given genre based on field experience and photographer consensus.

Scoring is opinionated and transparent. The weights and formulas are visible in the codebase. We acknowledge that no formula perfectly captures real-world performance, and encourage photographers to use scores as a starting point, not a final verdict.
