Sony a6700 vs a7 IV

Sony's top APS-C hybrid against its 33MP full-frame all-rounder. Both have 5-axis in-body stabilization, the NP-FZ100 battery, 10-bit 4:2:2 video and a 1.04M-dot fully articulating touchscreen. The a6700 adds AI subject recognition, 4K up to 120p and a much lighter body; the a7 IV has the larger sensor, a 3.69M-dot finder, two card slots and a full-size HDMI port.

Who should buy which

Buy the a6700 if…

  • You shoot birds, insects or vehicles: AI subject recognition from the AI processing unit.
  • You shoot video and want 4K up to 120p (cropped) or 4K/60 from the full sensor width.
  • You want the lighter body: about 493 g vs about 658 g with battery and card.

Buy the a7 IV if…

  • You want a full-frame sensor and 33MP for more cropping room and shallower depth of field.
  • You shoot events or weddings and want two card slots, including CFexpress Type A.
  • You want the sharper 3.69M-dot finder and a full-size HDMI port.

Both bodies use the NP-FZ100, 5-axis in-body stabilization, 10-bit 4:2:2 video and the same 1.04M-dot fully articulating screen, so the choice is sensor size, two card slots and the finder versus AI autofocus, 4K/120p and weight. See our full a6700 review and a7 IV guide, or all comparisons.
