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.

Pocket Vlogging — ZV-1 II (2023): The best pocket vlogging camera — 1-inch sensor, ultrawide zoom, flip screen, and real-time Eye AF in a shirt pocket.
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
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
ZV-1 II (2023)
- You create vlog content solo and want reliable face tracking in a genuinely portable camera
- You want a wide zoom range for shooting variety without ever changing lenses
- You want clearly better image quality and stabilisation than a smartphone, simply packaged
Quick take: The x-a7 has the highest resolution at 24mp; the x-a7 is the most affordable; only the om system tg-7 is weather sealed. Scroll down for the full spec breakdown.
