Should I upgrade from the Sony Alpha A7 III to the Sony Alpha A7 V?

Verdict

Upgrading is likely worth it. Both use the Sony E / FE mount, so your lenses fit directly.

What you gain

  • 33MP instead of 24MP
  • faster bursts (30fps vs 10fps)
  • faster sensor readout (≈15ms vs ≈65ms), so less rolling-shutter distortion
  • better video (4K 60p vs 4K 30p)
  • 7 years of newer processing and autofocus (2018 → 2025)

What you give up

  • noisier high ISO
  • a heavier body (690g vs 650g)

What it costs

Alpha A7 V new£2,399
Alpha A7 V used (MPB, typical)£2,110
Your Alpha A7 III trade-in (rough estimate)≈ £400
Net cost buying used≈ £1,710

Trade-in estimates assume about two-thirds of the typical MPB resale price; real offers vary with condition and shutter count.
