Verdictwhich should you buy?

EOS R50 — Beginners & Family: Canon's most beginner-friendly RF body — Dual Pixel AF and beautiful colour science in an approachable package.

A7S — Astrophotography & Low-Light: The original A7S pioneered the concept of a camera optimised entirely for low light. Its 12.2MP sensor has enormous photosites — extraordinary high-ISO performance that still holds up. Lacking IBIS and limited to 1080p internally (4K requires external recorder), it is a specialist tool. For astrophotography, event videography, or any scenario where light is genuinely scarce, it remains outstanding.
