Independent testing
How much independent testing exists for each mirrorless camera
Of the 8 mirrorless cameras we track, 8 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| OM System OM-1 | 2 | 12 | 2 |
| Nikon Zf | 2 | 4 | 2 |
| Sony Alpha A7 IV | 2 | 4 | 2 |
| Canon EOS R5 Mark II | 2 | 2 | 2 |
| Fujifilm X100VI | 1 | 12 | 1 |
| Canon EOS R6 Mark II | 1 | 1 | 2 |
| Nikon Z6 III | 1 | 1 | 2 |
| Sony Alpha A6700 | 1 | 1 | 2 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Mirrorless Cameras buying guide and the reviewers we cite.
