Sony's camera lineup can look like alphabet soup, but the naming scheme is actually a deliberate market segmentation tool, according to an Engadget explainer. The company divides its mirrorless cameras into full-frame and APS-C categories, with full-frame models using single digits (A1, A9, A7) and APS-C models using the A6xxx series. Higher numbers generally mean more capable and expensive cameras, as seen with the A6100, A6400, and A6700.

The suffixes attached to A7 models further refine the targeting. The A7R is built for resolution, the A7S for low-light video, and the A7C for compactness. The A1 and A9 sit at the top as professional tools, with the A9 III featuring a first-of-its-kind global sensor. This structure lets Sony charge premium prices for specialized capabilities while keeping entry-level APS-C models affordable for beginners.

However, the source also points to business implications beyond naming. Sony's dedicated FX video lineup may explain why the A7S series has not seen a new model since 2020. And the A6700, the top APS-C model, is now more than three years old, suggesting Sony is overdue to refresh that segment. For a company that relies on clear product tiers, those gaps could leave room for competitors—or signal upcoming releases.
