GearScore™ Verdict — Which should you buy?

Professional & Luxury Hybrid Shooters — Leica SL3 (2024): Leica's most capable mirrorless — 60MP, 30fps burst, 8K ProRes, and 7.5-stop IBIS with L-mount's growing lens ecosystem.

Astrophotography & Low-Light — A7S (2014): 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.
