The operating limits

Kingston specifies UHS-II and V90 for its 64GB Canvas React Plus card. Source

Both cameras use an approximately 1.5× Super 35 crop in 4K60. The 16mm end of the Sony wide zoom gives about a 24mm-equivalent view on either body. Source

Sony A7 IV specifications include a 33 MP sensor and 658 g operating weight. Source

The A7C II zoom kit includes the FE 28–60mm lens. Source

A7 IV movie media requirements vary by format and mode. Source

Sony's U.S. A7C II body MSRP is $2,199.99. Source

The 4K60 All-Intra budget uses one Sony SF-G128T/T1 128GB V90 SDXC card per camera. B&H listed it in stock at $243 on November 13, 2026. Budget a second card separately for redundant recording on the A7 IV. Source

Both budgets include the same Sony E-mount FE 16–25mm F2.8 G zoom at Sony's $1,299.99 U.S. MSRP. At 16mm, the 1.5× crop gives roughly 24mm-equivalent framing on either camera. Source

Sony specifies V90 SDXC for normal XAVC S-I 4K on the A7C II, up to 600 Mb/s. The A7 IV supports the same class of SD card. Source

Both bodies lock Super 35 on in 4K60. The editorial score assigns 3 points for the 1.5× crop, 2.5 for the V90 media requirement, and 0 for switching between these two bodies with the same Sony E-mount lens. Source

Sony's A7 IV heat-duration example uses XAVC S 4K at 30p/25p and 60 Mb/s, so it does not establish runtime in the benchmark recording mode. Source

Sony's A7C II heat-duration example uses XAVC S 4K at 60p/50p and 150 Mb/s. Thermal runtime is unscored because the manuals use different settings and neither example covers this All-Intra rig. Source
