How it works

Start with the kit. Then the specs. Then the job.

A comparison is three steps, in that order. The catalog is still being built; the method is already the one we will use.

01

System and mount

You buy a body. You commit to a lens mount. The fitting decides which glass you can use, and that usually outlasts the camera. Start there, not by lining up bodies across mounts that cannot share lenses.

02

Specs from manufacturer documents

Figures come from the maker’s own documents, recorded with a source and a date. Retailer listings and review roundups are not sources. If a figure is missing, the cell stays blank. Price, if shown, is dated.

03

The job

Weddings, wildlife, travel, video, stills — the job tells you which published fields to read first. It does not assign weights, scores, or a ranking. Bodies and lenses belong in the same table.

Limits

What a spec sheet cannot settle.

Optical quality is not inferred from a published resolution or an MTF chart on a brochure. Handling is not a verdict we write from a table. Price is not a ranking, even when a dated price is shown.
