Sony A7 IV vs A7 III: the 12 key differences



(Paradigm credit: Sony)

The Sony A7 Four is now out. Sony sees the A7 Four as a logical development of the all-purpose

, and 1 that’south better and more powerful in simply well-nigh every respect. But something has changed. It’s no longer Sony’southward entry-level full frame camera. That part is at present taken upwardly by the Sony A7 III, which will go on, and the

.

The fact is, while the A7 Four is only a lilliputian more than expensive than the A7 Iii when that camera was launched, it costs A LOT more than the A7 III does now.

That’s not all – the Sony A7 3 still stacks up well today, offering 4K video, 10fps shooting and one of the best AF systems effectually. Given the big deviation in toll, does the A7 4 have enough that’south improve to tempt yous into paying the extra?

That will depend on what yous like to shoot and the features that matter nigh to you, so to make that decision easier, we’ve picked 12 key differences, in the Sony A7 IV vs A7 3 battle, and what they hateful for everyday shooting.

Here goes…

ane: Resolution

Sony A7 IV

(opens in new tab)

• Sony A7 IV:
33.0MP
• Sony A7 III:
24.2MP

The Sony A7 4 has a new 33-megapixel sensor that offers significantly higher resolution for stills photography and also puts information technology one footstep ahead of similarly priced rivals from Nikon and Panasonic. Yet, the higher resolution does not make any departure to the maximum video resolution, which stays at 4K.

two. Maximum ISO (expanded)

• Sony A7 IV:
204800 (still), 102400 (video)
• Sony A7 III:
204800

Sony says that the new A7 IV has better racket command at loftier ISO settings than the older A7 III. Nevertheless, the maximum (expanded) ISO setting is the same at ISO 204800 for stills. Interesting, the A7 4 offers an expanded maximum for video that’southward 1EV lower at ISO 102400, where the A7 Iii’s stills and video ranges were the same. We look frontwards to testing the new photographic camera to see if there are visible real-world differences.

three. Continuous shooting

• Sony A7 Four:
10fps, 828 raw+JPEG
• Sony A7 III:
10fps, 79 raw+JPEG

Both the Sony A7 IV and the older A7 Three can shoot continuously at 10 frames per second – just at that place is a BIG deviation in the buffer capacity, which is the number of frames they can capture before slowing down. Sony quotes 79 raw+JPEG images for the A7 3, which is very good for a camera in this class, but practically unlimited raw+JPEG capture with the A7 Four, thanks to its new BIONZ XR processor and CFexpress Type A menu slot.

4. Stabilization

• Sony A7 4:
v.5 steps, Active mode/Standard stabilization
• Sony A7 Three:
five steps, Standard stabilization

Both cameras have 5-axis in-body stabilization, simply the A7 Iv boasts a slight improvement in stabilization of five.5 stops versus 5, and it also has a new ‘Active’ stabilization style.

5. Creative styles

• Sony A7 IV:
Artistic Looks
• Sony A7 Iii:
Artistic Styles

Sony has introduced a drove of new Creative Looks with the A7 IV. These seem more useful for videographers than stills photographers (especially those who adopt to shoot raw).

half dozen. Autofocus

• Sony A7R IV:
759 AF points, Human/Animal/Bird, Real-time Tracking, AF Assist, Focus Map, Breathing compensation
• Sony A7 Iii:
693 AF points, Human/Brute

The Sony A7 III already has a terrific hybrid contrast/phase-find AF organisation, so the A7 Iv offers more of an evolutionary step rather than a behemothic leap forward. It has a total of 759 AF points, up from 693 points for the A7 III, with Homo/Animal/Bird AF, Real-time Tracking AF, AF Assistance, Focus Map, Animate compensation. The AF Assist and Focus Map features could evidence useful for videographers, while the Breathing bounty works with compatible Sony lenses to counter the visual effects of focus breathing (changes in subject magnification when the focus changes) on the fly.

7. Video

(opens in new tab)

• Sony A7 Four:
Upwardly to 4K 60p (S35), ten-chip/4:two:ii, S-Log3/S-Cinetone
• Sony A7 3:
Upward to 4K 30p, 8-flake/4:2:0, South-Log3, Standard stabilization

For full width (uncropped) 4K video, both cameras top out at 30fps. However, the A7 4 offers of import advantages elsewhere. For instance, information technology offers 4K 60p capture in its cropped Super35 mode, and steps up from the A7 III’s 8-fleck/4:2:0 video capture to x-bit/4:2:two. This promises a much higher video quality when colour grading and using the camera’s South-Log3 loftier dynamic range way. The A7 IV also adds the Southward-Cinetone profile from Sony’s cinema cameras.

8. Way dial

• Sony A7 IV:
Way dial, Nonetheless/Movie/S&Q dial
• Sony A7 Three:
Mode dial

There are some concrete differences between the A7 Iv and the A7 Three. Ane of these is a reconfigured ‘stacked’ main manner punch which has a punch for switching between the camera’south Still, Movie and S&Q modes.

9. Viewfinder

• Sony A7 IV:
3.68m dot Quad VGA upwards to 120fps
• Sony A7 III:
2.36m dot XGA up to 60fps

The Sony A7 Iv also gets a amend electronic viewfinder, going upward in resolution from 2.36m dots on the older camera to iii.68m dots – and with a faster refresh charge per unit of 120fps versus 60fps.

10. LCD display

• Sony A7 IV:
Vari-bending
• Sony A7 III:
Tilting

The biggest physical change, even so, is the rear screen. On the A7 III it has a simple tilting mechanism and can’t face up forward, but on the new A7 IV information technology’s on a vari-angle hinge and is far more flexible. It looks equally if Sony may at last be moving over to vari-angle displays, which are and so much more useful for video.

eleven. Storage

CFexpress Type A menu

(opens in new tab)

• Sony A7 IV:
1x CFexpress Type A/UHS-Ii, 1x UHS-Ii
• Sony A7 3:
2x UHS-II

Both cameras have twin UHS-Two compatible SD card slots, but the A7 IV has a crucial difference – one of these slots tin also take even faster CFexpress Type A cards. These are smaller (and ultimately slower) than the CFexpress Type B cards used by other cameras, and then far information technology’south only Sony that has used this smaller format – but this does help give the A7 4 its significant performance advantages over the A7 III.

12. Connectors

• Sony A7 IV:
10Gbps USB iii.ii Gen2, HDMI Type A, WiFi 5GHz/2.4GHz/LAN
• Sony A7 III:
5Gbps USB iii.1, HDMI Type D, Wi-Fi two.4GHz

The Sony A7 Iv boasts faster connectivity all round than the A7 3. Its USB port supports 10Gbps USB 3.2 Gen2 transfer, as opposed to the 5Gbps USB 3.one on the older A7 3. The new camera besides offers a 5GHz LAN connection rather than the 2.4GHz maximum on the A7 III, and the A7 IV has an HDMI type A connector rather than the A7 Iii’s type D.

Sony A7 4 vs A7 III: conclusions

The curious thing is that if Sony was to launch the A7 III today, at its electric current prices, we would probably be raving over what it offers for the coin. This is still a powerful, constructive, do-it-all photographic camera – its video specs are starting to look somewhat stale, just for everyday 4K capture and equally a powerful stills camera, the A7 III still has what it takes.

However, the A7 IV is clearly superior in a number of respects – some subtle but important, others obvious and highly desirable. Sony has created a successor to the A7 III that is superior in practically every mode – but it’south likewise a lot more expensive to simply at today’due south prices.

And so perhaps it comes down to this: how much of the A7 4’s actress capabilities do you demand, and is information technology worth the big leap in cost to become them?

How we test cameras

We test mirrorless and DSLR cameras both in real-world shooting scenarios and in carefully controlled lab weather condition. Our lab tests measure resolution, dynamic range and indicate to noise ratio. Resolution is measured using ISO resolution charts, dynamic range is measured using DxO Analyzer test equipment and DxO Analyzer is besides used for noise analysis across the camera’southward ISO range. We use these real-earth testing and lab results to inform our comments in buying guides. For compact cameras and phones, we judge on real world handling and photographic results alone.
