Street, Travel & Everyday Photography — X100F (2017): The X100F is the camera that made the X100 series legendary — 24MP X-Trans III, a hybrid viewfinder, and the best fixed 35mm compact lens available.
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.
