Who should buy what
X-A7 (2019)

- You're new to mirrorless and want a small, uncomplicated first camera to learn on
- You want excellent in-body stabilisation to steady handheld video and shake-prone shooting
- You're drawn to the Micro Four Thirds ecosystem and want to start at the entry level
OM System TG-7 (2023)
- You dive, surf, kayak, ski, or hike and need a camera that genuinely survives anything

- You need a rugged compact for adventure, outdoor, and underwater activities
