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.
Sports, Travel & Dslr Shooters — Nikon D7500 (2017): The D500's BSI sensor in a compact, weather-sealed body — excellent high-ISO performance and DSLR reliability at a great price.
Creative Filmmakers & Experimental Photographers — Sigma fp (2019): The smallest full-frame camera in the world — Cinema DNG RAW and L-mount flexibility in a pocket-sized body that rewards creative shooters.
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
Nikon D7500 (2017)
- You're deeply invested in Nikon F-mount glass and aren't ready to switch systems
- You shoot wildlife or sport and still prefer an optical viewfinder response
- Note: consider the Z5 II or Z6 III if you're open to mirrorless for a future-proof investment
Sigma fp (2019)
- You're a filmmaker building a cinema rig where the smallest full-frame body is essential
- You want L-mount compatibility to pair with Sigma Art or Leica SL lenses
- You prioritise video and cinema colour over stills ergonomics and functionality
Quick take: The sigma fp has the highest resolution at 25mp; the x-a7 is the most affordable; only the nikon d7500 is weather sealed. Scroll down for the full spec breakdown.
