Should I upgrade from the Sony Alpha A9 II to the Sony Alpha A9 III?
Upgrading is likely worth it. Both use the Sony E / FE mount, so your lenses fit directly.
What you gain
- 24.6MP instead of 24.2MP
- faster bursts (120fps vs 20fps)
- faster sensor readout (≈0ms vs ≈6ms), so less rolling-shutter distortion
- better video (4K 120p vs 4K 30p)
- 4 years of newer processing and autofocus (2019 → 2023)
What you give up
- Nothing significant on paper
What it costs
