Sony’s new A7 IV full frame mirrorless camera is one of them The best “entry-level” mirrorless cameras in the market.Yes, there are higher resolution sensors, and you won’t find some high-end video features, but you’ll be hard-pressed to find better all-around mixed photos and camera.
This update adds a new 33-megapixel sensor, an insane, almost infinite buffer capacity – meaning you can pretty much keep shooting uncompressed RAW/JPG until the battery runs out – a vastly improved autofocus system , has better eye tracking, and supports more video capture modes, including Hybrid Log Gamma for playback on HDR TVs.
what is new
Physically, the A7 IV isn’t much different from its predecessor, although the grip is much larger, giving the camera a chunkier feel.The new grip is very similar to A7S III use.I find it less comfortable than mine A7RII, but how it feels depends on the size of your hand. I recommend checking out your local camera store if you can.Despite the increase in size, this is still one of our most compact full-frame cameras mirrorless camera guide.
The controls on the back are very close to what you’ll find on other recent A7-series cameras. There’s a four-way multi-controller that also acts as a dial, a joystick for positioning the AF point, and six programmable buttons. Enough external controls ensure you really only have to dive into the menu once to set everything up the way you want. It’s also a good thing, because Sony’s menu system is still a maze, and the less time you spend, the happier you’ll be.
The new highlights of the A7 IV are mostly on the inside. The A7 IV uses a new 33-megapixel backside-illuminated CMOS sensor that offers better resolution and possibly better image quality in low-light conditions. The new sensor is a step up from the A7 III (which has a 24-megapixel sensor) and what you’ll find in competitors like the Canon R6, Nikon Z6II, and Panasonic S1.
Meanwhile, the A7 IV remains the entry-level camera in Sony’s lineup. In terms of resolution, the A7R IV with its 60-megapixel sensor is still in its class. It’s worth noting that we’ll likely see the A7 IV’s sensor in the A7C’s successor, which I expect to see later this year — if you want a smaller camera body, you should wait.
While the sensor is new, the A7 IV’s processor comes from the video-centric Sony A7S III, which is known for its dynamic range. The A7 IV gets a similar boost, offering 15 stops of dynamic range, opening up a wealth of post-processing possibilities. The new processor also makes the A7 IV faster than its predecessor. (Sony claims it’s eight times faster.) I don’t have the A7 III to compare the two, but it never felt like the A7 IV was bogged down.
In addition to the processor and sensor, Sony’s new autofocus system – first seen in the flagship A9 – is finally coming to the A7 series. The improvements here are hard to overstate. This system, which Sony calls “real-time tracking,” is smart and fast.
I test six high-end mirrorless cameras every year, and each promises faster autofocus, but judging by the results, most are indistinguishable. I’ll admit, in my own time, I’ve only shot with manual focus lenses. I’ve been shooting manually since I picked up my first Minolta SR-T in 1988, and I’m pretty fast now. In most situations (excluding wildlife and sports), I had fewer out-of-focus images with manual focus than with the latest and greatest autofocus. That is, until the A7 IV.
