Sony ZV-E1 / Sony α7 IV (ILCE-7M4)

A low-resolution full-frame sensor gathers more light per pixel, at the cost of limited room for cropping stills.

Back illumination moves the wiring behind the light-sensitive layer, helping reduce noise in low light.

Subject recognition covers humans, animals, birds, insects, cars, trains and aircraft.

Phase-detection points track the subject quickly; eye detection locks focus on the eye of moving people and animals.

There is no mechanical shutter; the line-by-line readout of the electronic shutter can skew fast-moving subjects.

XAVC HS uses H.265 and XAVC S uses H.264; XAVC S-I uses intra-frame coding, which is lighter to edit but takes much more space.

The shoe’s digital audio interface lets compatible Sony microphones send audio to the camera digitally without a cable.

USB PD support allows the camera to be powered during recording from a suitable adapter or power bank.

The figure is measured with the Planar T* FE 50 mm F1.4 ZA for pitch/yaw only; it varies by lens and conditions.

The 120 fps finder setting shows a smoother view when following moving subjects.

XAVC S-I compresses each frame individually; it is easy to edit but takes much more space. 10-bit 4:2:2 reduces banding when grading.

Fast cards are needed for high-bitrate S&Q and S-I recording.

USB PD lets the camera run from a power bank or adapter during long shoots.

The coating aims to reduce dust sticking to the sensor; Sony gives no moisture-resistance rating on this page.
