Sony digital camera model numbers explained: Bigger isn’t always better

Sony’s camera model names indicate broad differences in format, intended use and price, but the mix of letters and numbers can make choosing a model confusing. The article explains that Sony’s mirrorless cameras use the Alpha name and interchangeable lenses, while its compact cameras have fixed lenses; within the mirrorless range, full-frame models generally cost more than APS-C models.

Among full-frame cameras, the A1 targets professionals with high resolution and speed, while the A9 prioritises fast action and the A7 range serves a wider audience, with variants focused on general use, resolution, video or compact size. The article gives examples including the A9 III’s 120-frames-per-second RAW shooting, the A7R VI’s 67-megapixel sensor, and the A7 V’s 33-megapixel sensor; Roman numerals indicate a model’s version.
