Which should you buy?
Beginner Fujifilm — X-A7 (2019): The most affordable X-mount entry — Fujifilm colour and film simulations with a large flip screen for beginners.
Hybrid Photo & Video — X-S20 (2023): Fujifilm's most accessible X-series body — 7-stop IBIS, 6K video, 20 film simulations, and a user-friendly layout.
Adventure, Underwater & Outdoor Use — OM System TG-7 (2023): Waterproof to 15m, freezeproof and shockproof — the TG-7 is the most capable rugged compact for adventure and outdoor use.
Who should buy what
X-A7 (2019)
- You want an affordable first mirrorless with decent video capabilities
- You shoot a lot of selfie-style content or vlog on a budget
- Note: no viewfinder and limited lens support — the X-T30 II is a better long-term investment
X-S20 (2023)
- You primarily create video content and want a capable but compact Fujifilm
- You're a vlogger, travel creator, or documentary shooter
- You want Fujifilm film simulations with strong, reliable video specs
OM System TG-7 (2023)
- You dive, surf, kayak, ski, or hike and need a camera that genuinely survives anything
- You want a waterproof backup or travel camera that doesn't require a separate housing
- You need a rugged compact for adventure, outdoor, and underwater activities
