  3. 3Sony a7 IV, In-body image stabilization: CIPA rating measured with the 50mm F1.4 ZA test lens attached.
  4. 4Sony RX100 VII, In-body image stabilization: Sony rates the optical (lens-shift) SteadyShot at 4.0 stops at the 200 mm telephoto end, not a body-only CIPA figure.

  6. 6Sony a7 IV, Continuous shooting (mechanical): 10 fps applies to compressed RAW/JPEG/HEIF; drops to 6 fps for lossless or uncompressed RAW.
  7. 7Sony RX100 VII, Continuous shooting (mechanical): The 'Hi' burst setting is electronic-shutter only; 10 fps ('Mid') is the fastest mechanical-shutter continuous rate.
  8. 8Sony RX100 VII, Continuous shooting (electronic): Blackout-free 20 fps continuous includes AF/AE tracking; the separate 'Single Burst' mode takes 7 shots at up to 90 fps.
  9. 9Nikon Z9, Pre-burst capture duration: Pre-Release Capture is only available in the C30 and C120 high-speed frame capture modes.
  10. 10Sony RX100 VII, AF subject detection: Maker names only human and animal recognition (Eye AF / Real-time Tracking); no bird or vehicle categories are listed.
  11. 11Sony a7 IV, 4K max frame rate: 4K 60p is only available in Super35mm crop; full-frame 4K tops out at 30p.

  15. 15Sony RX100 VII, Raw video recording: Sony's movie-format list contains only XAVC S (H.264) and AVCHD; no raw video output is offered.

  17. 17Sony a7 IV, Video dynamic range (log): Sony's claim for S-Log3 per internal tests; stated as 15+ stops.
  18. 18Sony a7 IV, Screen size: Sony rates the panel at 2.95in (3.0-type); most sources round to 3in.
  19. 19Sony RX100 VII, Screen articulation: Screen tilts up about 180° for selfies and down about 90°; it does not swing outward like a fully articulated display.
  20. 20Sony a7 IV, Rear screen resolution: 1,036,800 dots; Sony's retail pages round this to 1.03 megadots.
  21. 21Sony a7 IV, Battery life: 580 shots per charge with the rear LCD; 520 with the EVF.
  22. 22Sony RX100 VII, Battery life: 260 shots assume default monitor settings; Sony also lists 310 shots when 'Auto Monitor Off' is set to 2 s.
