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.
Compact Street & Travel Photography — X-E4 (2021): The X-E4 is for photographers who want the minimum camera that still delivers maximum image quality. If you love shooting from the rear screen and want the smallest possible X-mount body, this is your camera. If you need a viewfinder or IBIS, look at the X-S20 or X-T30 II.
Travel & Lightweight Outdoor Photography — Olympus OM-D E-M5 III (2019): The lightest weather-sealed MFT camera — compact, travel-friendly, and capable with 7.5-stop IBIS in a body that fits in a jacket 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
X-E4 (2021)
- Street photographers who prioritise portability and discretion
- Travel photographers packing minimally
- Fujifilm fans who shoot primarily from the rear screen
- Anyone who wants the X-Trans sensor in the smallest possible body
Olympus OM-D E-M5 III (2019)
- You want a lightweight, sealed camera for travel and outdoor photography
- You're new to Micro Four Thirds and want a capable mid-range body with excellent stabilisation
- Note: consider the newer OM-5 for updated specs in a similar compact form factor
Quick take: The x-e4 has the highest resolution at 26mp; the x-a7 is the most affordable; only the olympus om-d e-m5 iii is weather sealed. Scroll down for the full spec breakdown.
