Sony A7 IV Review: Still the Smartest All-Rounder in Full Frame
Four years after launch, the Sony A7 IV is still the camera I recommend first to anyone asking me what to buy, and the price drops since launch only make the case stronger than it was in 2021. I've spent time with the newer bodies in Sony's lineup, and I keep coming back to the same conclusion: this one still does almost everything well enough that most people don't need to look further.
It's a full-frame mirrorless body built around a 33-megapixel BSI-CMOS sensor, launched at $2,499 in late 2021 and now commonly found between $1,500 and $2,000 depending on condition and whether you buy new or used.
Why the sensor jump mattered
Moving from the 24-megapixel sensor in the A7 III to 33 megapixels here sounds like a modest spec bump, but it shows up in real use. Cropping into a frame for a tighter composition, or printing larger than you'd normally attempt, both benefit from that extra resolution without the file sizes becoming genuinely unwieldy the way higher-megapixel bodies can.
Autofocus that holds up against newer competition
This is where the A7 IV earns its reputation. Real-time eye tracking for both humans and animals locks on reliably and holds through a subject turning their head or moving through a frame, and reviewers consistently describe the autofocus system as a genuine leap over the A7 III rather than an incremental refinement. It's not the newest AI-driven system Sony has shipped since, but it's close enough that most people won't notice the gap in everyday shooting.
Video capability, with one real caveat
4K video tops out at 60p, but that mode applies a meaningful sensor crop, something worth knowing before you buy if 4K60 uncropped matters to your work. Standard 4K30 uses the full sensor width with pixel-binning that most reviewers rate as detailed and clean, and 10-bit color depth gives real flexibility in grading footage afterward.
Handling and everyday ergonomics
The body sits comfortably between compact and substantial, with a deep enough grip that a full day of shooting doesn't leave your hand cramping the way some smaller mirrorless bodies can. The fully articulating screen, a genuine upgrade over the A7 III's simpler tilt mechanism, makes vlogging and awkward-angle shooting considerably easier.
Where it shows its age
Rolling shutter on the electronic shutter is more noticeable than on newer stacked-sensor competitors, something to watch for if you shoot fast action or pan quickly during video. The single CFexpress Type A slot, paired with an SD slot, is also a point of friction, since CFexpress Type A cards remain more expensive and less common than the Type B cards used by some competitors.
Battery life and everyday reliability
Rated for roughly 580 shots per charge using the EVF, the NP-FZ100 battery has a strong reputation for real-world endurance, and it's the same battery used across most of Sony's recent full-frame lineup, which is convenient if you're already invested in Sony gear.
Price and where it sits today
With Sony's newer A7 V now available and pushing used A7 IV prices down further, this camera has moved from flagship pricing into genuine value territory. At $1,500 to $2,000 for a well-maintained used body, or under $2,000 new during regular sales, it undercuts most comparably capable full-frame hybrids on the market.
What reviewers and owners consistently praise
- Class-leading autofocus that holds up against much newer competition
- 33-megapixel resolution that balances detail against manageable file sizes
- Strong, dependable battery life across long shooting days
- A genuinely useful fully articulating screen for video and awkward angles
What consistently comes up as a drawback
- 4K60 video applies a noticeable sensor crop
- Rolling shutter is more visible than on newer stacked-sensor bodies
- CFexpress Type A cards remain pricier and less common than alternatives
- Menu system, while improved over older Sony bodies, still takes real time to learn
Five years after launch, most reviewers still land on the same conclusion: this remains one of the smartest all-around full-frame choices available, particularly now that the price has come down from where it started.
Who this camera actually suits best
Reviewers and owners consistently describe the A7 IV as the camera for someone who doesn't want to specialize narrowly, wedding and event shooters who need both stills and reliable video, hybrid content creators, and enthusiasts who haven't settled into one specific genre yet. It's less clearly the right choice for someone whose work is purely fast-action sports or wildlife, where the newer stacked-sensor bodies in Sony's lineup, and Canon's R6 Mark II, generally outperform it on burst speed and rolling shutter control.
How it holds up against Sony's own newer bodies
With the A7 V now on the market, a natural question is whether the A7 IV is simply outdated. The consensus among reviewers is that the core photographic experience, autofocus reliability, image quality, and handling, remains close enough to current-generation performance that the price difference matters more than the capability gap for most buyers, a genuinely unusual position for a four-year-old camera to still hold in a category that typically sees rapid generational leaps.
The used market consideration
Because this camera has been in production long enough to build a substantial used market, buying secondhand from a reputable dealer with a return policy is a widely recommended path for anyone comfortable with used gear, often bringing the price down meaningfully further than even the current new-unit discounts while carrying manageable risk given how well-documented this camera's reliability track record has become over its production run.
