Overview
The Sony Alpha 7 IV is a full-frame mirrorless camera built around a 33 megapixel Exmor R back-illuminated sensor, sold here as the ILCE7M4/BQ body. It sits between Sony's video-focused A7S line and higher-resolution A7R line, aimed at photographers who shoot both stills and video on one body.
Sony calls out the BIONZ XR processor as 8 times more powerful than the previous generation, which is what enables 4K at up to 60p with full pixel readout instead of line-skipped footage. The 4K 30p mode goes further with 7K oversampling and no pixel binning, a detail that matters for video sharpness more than the headline resolution number does. Sony also includes S-Cinetone, a color profile built to approximate its Cinema Line cameras without a full color grading workflow.
- 33MP full-frame Exmor R BSI CMOS sensor
- BIONZ XR processor, 8x the prior generation
- Built for live streaming and real-time sharing
- Rated 100-240V, 50/60Hz power input
Who it's for
Suited to photographers and videographers who want one full-frame body for both stills and serious video, including live streaming. Less suited to buyers who only shoot stills occasionally and do not need 4K 60p or oversampled video, where a simpler body would cost less.
Pros and cons
- 33MP sensor works for both stills and 4K video
- 4K 60p with full pixel readout
- 7K oversampled 4K 30p with no pixel binning
- S-Cinetone color profile built in
- Body only, no lens included
- No seller description or review data supplied with this listing
- Hybrid feature set costs more than a stills-only body
Performance notes
Full pixel readout in every 4K mode means the sensor is not skipping lines to hit frame rate, which keeps detail and reduces moire compared to cameras that do. At 4K 30p specifically, Sony oversamples from 7K and bins no pixels, and the BIONZ XR processor is rated to handle that data throughput at 8 times the previous processor's power. The camera is rated to operate between 32 and 104 F.
