Sony A7 IV overview: Mirrorless magic
(Pocket-lint) – For near a decade, Sony’s Alpha lineup has been the selection of many filmmakers and creators.
The explanation for that is easy: these cameras provide nice efficiency in a compact type, primarily supplying you with a extremely high-end software that is additionally simple to hold round.
Within the full-frame market, all the things started with the Sony A7’s launch in 2013. And with 2018’s Sony A7 III persevering with the road’s legacy as being the mirrorless all-rounder vary to contemplate, how does the A7 IV stack up?
Properly, one factor is for certain – it is not low cost. As Sony has proved many instances earlier than, although, worth is finest discovered within the efficiency and have set.
Sony describes the A7 IV because the entry-level, primary mannequin in its full-frame collection. And technically, it’s. Nevertheless, do not let that idiot you into considering the A7 IV is definitely only a primary or entry-level digital camera. It is not.
It is probably not low cost, however it provides greater than sufficient energy and flexibility to justify that price ticket.
For many who need a digital camera that is good at each images and video, there are few, if any, mirrorless cameras as compelling on this value vary proper now.
It is an important place to begin for many who need to improve to a ‘correct’ digital camera, whereas additionally being adequate to fit into an expert workflow as a ‘B’ digital camera for capturing extra cutaways on the fly.

Design
- 131.3 x 96.4 x 79.8 mm
- 658g physique weight – together with the battery and SD card
- E-mount for interchangeable lenses
We’ve lengthy loved the compact type of Sony’s full-frame providing. Whereas the A7 IV is not tiny – to not the degrees of the A7c, no less than – it’s nonetheless compact and straightforward to hold round.
It’s not likely any greater than Panasonic’s micro four-thirds cameras, just like the GH5 and GH6, and but nonetheless matches in a full-frame sensor.
It feels sturdy and well-made, too. The chassis is strong, with a reassuring heft, though, even then, it is mild sufficient that it’s simple to make use of handheld. That is helped additional by the beneficiant dimension of the grip that protrudes out of the entrance, and is coated in grippy rubber to make sure you don’t drop it simply.
There are a load of buttons and dials dotted across the physique, as nicely, which is helpful. Nevertheless, as a result of it’s Sony, these are additionally a bit of inconvenient. Some simply don’t appear to be notably nicely positioned. As an illustration – in traditional Sony model – the ‘Menu’ button isn’t inside simple attain of the correct thumb. It sits to the left of the viewfinder, as a substitute.
So should you’re gripping it along with your proper hand, there’s no approach you’ll get to the primary menu with out utilizing your left.
Different dials and buttons are fairly much more handy. Then there’s the dial for switching between picture, video and Gradual & Fast modes, which sits beneath the shot preset dial. It’s effective actually, and the very fact it’s locked by default means you gained’t by chance change to ‘Photograph’ mode when capturing a video.
Behind which might be two extra dials which, when set in guide mode, regulate the shutter velocity and publicity compensation by default. There’s additionally a grippy little directional joystick on the again that allows you to regulate the main focus level manually when in autofocus mode. Add that to the 4 programmable customized perform buttons, directional navigation wheel and the devoted film button, and you’ve got just about something you want.
Fortunately, the times of Sony not adopting a correct flip-out display screen are behind us. The A7 IV has one.
Which means you possibly can flip it out to face the identical course because the lens, making it simpler to movie your self. It additionally rotates about 270-degrees to face forwards or backwards, or have it face down for these instances you shoot whereas holding the digital camera up above your head.
The one challenge with that flip-out display screen is that it does block the ports a bit of when it is dealing with ahead, stopping easy accessibility. Plus, should you’re truly utilizing these ports whereas filming, you may be blocking the view of the show.
Ports and connectivity
- Twin reminiscence card slot – SD and CFExpress Sort A
- HDMI, Sort-C (with Energy Supply), 3.5mm enter and output
- 2.4Ghz/5Ghz Wi-Fi – Bluetooth LE
It is 2022, and that naturally means any self-respecting digital camera maker ensures you’ve sufficient ports to make it helpful for video seize. For Sony, meaning 3.5mm enter and separate 3.5mm output for microphones and headphones respectively.
There is a USB-C port for connecting to your pc for file switch, however, crucially, the A7 IV additionally helps Energy Supply for charging on the go. Then, in fact, there’s the HDMI port for hooking it as much as a monitor or exterior recorder monitor.
As for card help, you get two reminiscence card slots. Each help SD playing cards, however the first slot can also be appropriate with CFExpressA, which is Sony’s personal CFEpxress card format. It’s smaller than the type utilized by Panasonic’s GH6, however it could learn and write and sooner speeds than SDXC. That is helpful for the instances you need to shoot in excessive bitrate file codecs.
It is also geared up with wi-fi connectivity through dual-band (2.4/5Ghz) Wi-Fi, as nicely, as low power Bluetooth. This allows wi-fi file switch and distant management perform through your smartphone.
What’s it like to make use of?
- Actual-time AF/monitoring for people, animals and birds
- Respiration compensation
- 1.3cm digital viewfinder (OLED)
- NP-FZ100 battery
Like several digital camera, an enormous a part of what impacts how the digital camera feels is impacted by the lens you employ with it. On condition that Sony despatched us a main, wide-angle 14mm f/1.8 lens, that did restrict the expertise considerably. There’s solely a lot you are able to do with a lens that doesn’t zoom and, being wide-angle, isn’t at all times eager on focussing on shut up objects.
Nevertheless, whereas the lens wasn’t excellent for all situations, there are many issues to like about the best way the A7 IV handles itself, and an enormous a part of that’s the superior sensor and processing make-up. Simply as we’ve skilled with earlier current Sony cameras, the velocity at which it operates is actually spectacular.
Stick it in autofocus and also you’ll get eye-tracking in real-time by default. So, whether or not you’re capturing an individual or an animal, if their eyes are in view, it’ll lock on and observe them. And it does so reliably, too. If you wish to manually observe an object, you possibly can merely contact it on the display screen. It stays locked on whether or not it strikes, otherwise you transfer. For probably the most half, that works nicely.
For nonetheless images, the velocity at which it could lock on to an space and shoot a photograph is actually spectacular. Generally it feels a bit too quick, and might truly begin to really feel like a belief train simply believing the digital camera has targeted on the correct space.
There are a few parts that may make the Sony digital camera a bit of difficult to make use of, although, they usually’re the identical as we have seen in most up-to-date fashions.
Firstly, the very fact you possibly can’t simply press the shutter button to start out recording a video appears uncommon, particularly when you must be within the devoted video mode to shoot it within the first place. As an alternative, you get advised off by the A7 IV and instructed to press the tiny, fiddly purple button as a substitute.
Secondly, Sony’s menu system within the software program is difficult to get accustomed to. There are such a lot of choices in there to customize the expertise and settings, and, whereas this can be a optimistic in some respects, it additionally makes it long-winded and unintuitive to navigate round.
Battery life is fairly robust, nonetheless, for a digital camera this highly effective. We by no means discovered ourselves panicking about how lengthy we may shoot for. What’s extra, because it has USB-C that accepts energy, you possibly can plug it right into a battery pack whereas on the transfer to high it up whilst you’re not utilizing it.
Photograph and video
- 33MP Exmor R CMOS 35mm full-frame sensor
- Bionz XR ISP – as much as 10fps bursts
- 4:2:2 10 bit 4K/60 video
- 5-axis SteadyShot stabilisation
On the coronary heart of the A7 IV lies the newest 33-megapixel Exmor R full-frame sensor, paired with the highly effective Bionz XR picture processing unit. It is an important pairing, and, together with some intelligent thermal administration, allows some excessive bitrate and excessive body charge recording at 4K decision.
It shoots 14-bit RAW, plus 4:2:2 10-bit video at 4K/60, and meaning you will get sharp, clean footage – particularly when utilizing the 5-axis stabilisation. Crucially for anybody who does lots of color correction, the 10-bit knowledge additionally means you get lots of room to tweak colors, stability, publicity, highlights and the like with out shedding element or making the image noisy.
With regards to color correction, you additionally get a number of image profiles to select from. These embody S-Log2 and S-Log3, in addition to a number of totally different HLG modes for HDR seize. These be part of a handful of Cine modes, and the same old commonplace automated film setting. In order for you, you possibly can even regulate and fine-tune your personal customized preset, with the built-in display screen providing a good preview of what it’ll appear to be on a well-balanced monitor afterwards.
The tip end result with video is a colour-rich image with sharp particulars and well-controlled publicity/shadows in automated mode. It did not appear to wrestle with something, with the aforementioned autofocus and real-time monitoring holding topics sharp.
With the F/1.8 lens, we have been utilizing it additionally meant some fairly dramatic depth of subject, with some beautiful, natural-looking bokeh/background blur. After all, at its peak, that additionally meant a really slender space of focus, however, with the correct topic and in the correct setting, it is efficient. As an illustration, when capturing merchandise in a cramped house, it could assist add some depth that in any other case would not be there with all the things so shut collectively.
We did not discover any important points with any of the footage or stills. Even within the shadows, or with barely lower-than-optimal mild ranges, it can provide good element with out extreme noise. And, regardless of having fairly a wide-angle lens, the degrees of distortion have been low too.

However do not let that idiot you into the considering the A7 IV is a primary or entry-level digital camera. It is not.
