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.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
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

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
Sigma fp L (2021)
- You need the highest resolution available in the smallest possible full-frame mirrorless
- You shoot architecture, landscape, or commercial work where fine detail is absolutely critical
- You want the cinematic flexibility of the fp platform paired with maximum megapixel count
