Professional Video, Documentary & Hybrid Commercial Work — EOS R5 C (2022): Canon's R5 reborn for cinema — 8K RAW unlimited, Cinema EOS colour science, and 45MP stills in a weather-sealed body.
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.
