How the VS Score works — and what it can’t tell you
Every measurable spec is scored relative to this matchup: the best value here earns 100%, the worst 0%, and everything between scales linearly. Each spec then counts according to an editorial weight that reflects real-world impact — a battery-capacity gap moves the score far more than a colour-options list. The category scores above are the weighted results inside each group, and the overall VS Score rolls all of them together; the evidence line under each category names the specs that actually decided it.
Unknown values are never estimated. A spec a product doesn’t report simply drops out of that product’s scoring — it isn’t penalised with a guess — and a spec only one side reports can never produce a “win”. The trade-off is honest but real: a thinner spec sheet means a score built on fewer data points, which is why the completeness figures are disclosed under About this data.
Most importantly: a spec-sheet lead is not the same as a better product. Megapixels, gigahertz and benchmark points describe capacity, not experience — image processing, software optimisation, thermals, haptics and ergonomics decide how a device actually feels, and no table captures reliability or long-term support quality. Treat the scores as a structured summary of what can be measured, read the caveats under each key difference, and use the weight tuner to re-rank the comparison by what matters to you.

About this data
Specifications are compiled from each manufacturer’s official spec sheet, cross-checked against trusted specification databases, and normalised into one schema so identical things are compared identically.
Specifications last verified July 5, 2026.
Data completeness: Canon R5 Mark II 96% and OM System OM-1 Mark II 96% of the 27 specs in this category. Anything we could not verify is shown as Unknown — never estimated — and is excluded from all scores.
Prices and availability come from live retailer feeds via our shopping partners and refresh throughout the day; a missing price means no partner currently lists the product, not that it is discontinued.
