Key Features in Depth

The 33MP resolution strikes the sweet spot: detailed enough for cropping and prints, but with manageable file sizes.
Backside-illuminated (BSI) design improves low-light performance.
Dynamic range is excellent, retaining highlight and shadow detail in difficult lighting.

2. BIONZ XR Image Processor

Same processor as Sony’s flagship A1.
Delivers faster AF tracking, better noise reduction, and advanced video capabilities.
Speeds up buffer clearing and continuous shooting.

3. Autofocus System

759 phase-detection AF points cover 94% of the frame.
Real-time Eye AF works for humans, animals, and even birds.
Lock-on tracking is sticky and reliable for sports, wildlife, and portraits.
Performance is nearly instantaneous in stills and video.

4. Video Capabilities

4K 60p recording with 10-bit 4:2:2 internal = pro-grade flexibility.
S-Log3 and S-Cinetone profiles for cinematic grading.
Full pixel readout in 4K 30p, oversampled from 7K = maximum detail.
No recording limit thanks to heat management.

For hybrid shooters, this makes the A7 IV one of the best video-capable stills cameras in its price class.

5. In-body Image Stabilization (IBIS)

5-axis stabilization up to 5.5 stops.
Smooth handheld video.
Sharper stills at slower shutter speeds.

6. Build & Ergonomics

Lightweight, compact — a good starter lens for general use.

For advanced users, upgrading to fast primes (35mm f/1.8, 85mm f/1.8) or Sony G Master zooms (24–70mm f/2.8) unlocks the full potential.
