Sony α7 vs Sony FX30

The bottom line

These sit in different sensor classes, and that decides most of it. The Sony α7 is full-frame (474g (1.04 lb), $1,699) — larger sensor, shallower depth-of-field and cleaner high-ISO. The Sony FX30 is APS-C (561g (1.24 lb), $1,899), trading some of that for a lighter, cheaper body and extra effective reach from lenses. Pick the format that matches how you shoot before splitting hairs on features.

Choose the Sony α7 if…

  • You prioritise shallow depth-of-field and clean high-ISO — its full-frame sensor is larger than the APS-C one, so backgrounds blur more and noise stays lower in dim light.
  • You value portability — at 474g (1.04 lb) it's noticeably lighter than the 561g (1.24 lb) alternative for travel and all-day carry.

Choose the Sony FX30 if…

  • You shoot action, sports or wildlife — 10fps burst plus dedicated subject-tracking AF keeps up with fast, erratic movement where 5fps would drop frames.
  • You shoot video seriously — it brings 10-bit internal colour, Log for gradable footage, no per-clip recording limit (vs a 29-min cap) and both mic and headphone jacks for monitored audio.
  • You vlog or shoot handheld solo — the fully-articulating screen flips to face you and there's a mic input for clean audio.
  • You shoot in low light or indoors — a higher native ISO ceiling (51,200) and AF that focuses down to -6 EV give it the edge after dark.

Where they differ

  • Video: the Sony FX30 is the stronger video tool — 4K up to 120p, 10-bit internal and Log.
  • Price: the Sony α7 launched at $1,699, $200 under the Sony FX30 — money that could go toward glass.
  • Burst: the Sony FX30 shoots 10fps to the Sony α7's 5fps — the gap that decides whether you nail the peak moment in sports and wildlife.
  • Card slots: the Sony FX30 has dual slots for instant backup — the reliability paid work depends on.
  • Weight: the Sony α7 is 474g (1.04 lb) vs 561g (1.24 lb) — 87g you'll feel on a long day out.
