Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII

Sony RX100 III vs RX100 VI vs RX100 V vs RX100 VI vs RX100 VII

The original Sony Cyber-Shot RX100 was a landmark release, with excellent image quality and high-speed performance, all packed into a metal body around the size of a pack of playing cards. We’re now on the seventh iteration of the RX100, and bizarrely many of these models, are still available as new today – and some of these offer great camera deals.

Although the heart of the RX100 range has remained the same, Sony has added various features and made changes to the handling of each successive release. In this article, we compare what the last five models in the line offer. As you are likely to find the RX100 Mark III, Mark IV, Mark V, Mark VI, and flagship Sony RX100 VII all on sale - this guide will help you choose which one of this family of premium compact cameras is the one for you.

These aren’t the cheapest cameras, so by looking at where the models are the same and where they differ, you'll have better idea of which makes the most sense against your budget.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Sensor and processor

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Sony RX100 III (DSC-RX100M3): 1in BSI Exmor R CMOS sensor, 20.1MP
Sony RX100 IV (DSC-RX100M4): 1in BSI Exmor RS CMOS stacked sensor, 20.1MP
Sony RX100 V (DSC-RX100M5): 1in BSI Exmor RS CMOS stacked sensor, 20.1MP
Sony RX100 VI (DSC-RX100M6): 1in BSI Exmor RS CMOS stacked sensor, 20.1MP
Sony RX100 VII (DSC-RX100M7): 1in BSI Exmor RS CMOS stacked sensor, 20.1MP

Although the sensors inside the five models aren't quite the same as each other, each offers a 20.1MP pixel count and works in concert with a BIONZ X processing engine

Although all the models in the RX100 line so far have offered 20.1MP 1in-type sensors, they have not been the same sensors.

While the RX100 III maintains the back-illuminated sensor of the Mark II, the RX100 IV features a sensor with a stacked architecture. This was done to improve light-gathering efficiency, helping to deliver images with lower noise.

That sensor also includes a separate DRAM chip, something that was maintained for the Sony RX100 V, RX100 VI and RX100 VII. Even so, Sony did not simply use the same sensor one for the last three models; instead, it incorporated phase-detect AF pixels into the sensors inside the RX100 V and onwards – more on this later.

Four sensors offer a native sensitivity range of ISO 125-12,800, and extensions on either side of this, but the native ISO range of the RX100 VII goes a little lower to ISO 100.

All five models also make use of a BIONZ X processor, although Sony has made a habit of improving processing for each model. These improvements are typically centered around better noise reduction and faster autofocus although those wanting to use these cameras for action will also no doubt be interested in burst shooting differences, which we’ll come on to later.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Lens

Sony RX100 III: 24-70mm (equiv.) f/1.8-2.8; ND filter
Sony RX100 IV: 24-70mm (equiv.) f/1.8-2.8; ND filter
Sony RX100 V: 24-70mm (equiv.) f/1.8-2.8; ND filter
Sony RX100 VI: 24-200mm (equiv.) f/2.8-4.5; ND filter
Sony RX100 VII: 24-200mm (equiv.) f/2.8-4.5; ND filter

All five models have a Control Ring around the lens, which can be used to change different settings such as aperture and ISO

Since the RX100 III, things were relatively consistent with regards to optics. The 24-70mm f/1.8-2.8 ZEISS Vario-Sonnar T* lens remained the same, offering a good balance of zoom range, portability and maximum aperture.

That all changed with the RX100 Mark VI, with its far longer 24-200mm (equiv.) f/2.8-4.5 ZEISS Vario-Sonnar T* optic, although Sony had somehow managed to incorporate the lens into a body that was almost the same size as before. True, the maximum aperture isn’t quite as impressive as before, but still respectable for this focal range and still an achievement. What’s more, it suddenly made the range a viable choice for travels and holidays, where one may have otherwise opted for a Panasonic TZ model or an interchangeable-lens camera.

All five models have also been designed with a Control Ring around their respective optics, and these can be used for a range of purposes – not least zooming. Each also has a built-in ND filter to help out when capturing long exposures and for video shooting.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Video

Sony RX100 III: 1080p up to 60fps, 120fps slow motion
Sony RX100 IV: 4K up to 30fps, 960fps slow motion
Sony RX100 V: 4K up to 30fps, 960fps slow motion
Sony RX100 VI: 4K up to 30fps, 960fps slow motion
Sony RX100 VI: 4K up to 30fps, 960fps slow motion

All five models boast strong video specs, but this is one area where they differ. Pictured above is the RX100 IV

Sony has been at the cutting edge of developing video technology in cameras primarily designed for photography, so it's no surprise that many differences can be found between these three models here.

The RX100 IV, RX100 V, RX100 VI and RX100 VII can shoot 4K video at 30fps, while the RX100 III is restricted to Full HD (1080p) shooting at frame rates up to 60fps. Sony has also added an S-Log2 video profile in both the RX100 IV and RX100 V, which makes these feel all the more video-centric, and pushed this further on the RX100 VI and RX100 VII with an S-Log3 option and and Hybrid Log Gamma profile for HDR displays.

Although the RX100 IV, RX100 V, RX100 VI and RX100 VII are all capable of 4K video recording, the way this is captured is not the same. The RX100 V and later oversample footage at a 5K resolution, before this is downsampled to 4K, a process that should make for slightly crisper results. All three, however, have an anti-distortion shutter for reducing rolling shutter effects, something that wasn't included on the RX100 III.

The Sony RX100 VII does have 4K Active SteadyShot that Sony says is 8x more effective than 4K Standard SteadyShot, an external microphone socket and support for shooting video in the vertical format.

The top plates of the RX100 IV, RX100 V (pictured) and RX100 VI make the presence of 4K video clear. The RX100 III, meanwhile, has a Full HD recording option instead

One of the headline features of the RX100 IV and later is what Sony calls High Frame Rate (HFR) videos. Users can shoot at up to a staggering 960fps for slow-motion output, although this comes at a reduced resolution. Essentially, the faster you go in frame rate the lower the output resolution.

You can also shoot slow-motion footage with the RX100 III, but only to a frame rate of 120fps, which is output at 720p. There's also a 1.69x crop factor to take into consideration here.

Unsurprisingly for such small cameras, you won't find ports for headphones on any of these models, though the addition of a mic socket on the RX100 VII will make this camera much more appealing to vloggers.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: AF system

Sony RX100 III: 25-point contrast-detect AF system
Sony RX100 IV: 25-point contrast-detect AF system
Sony RX100 V: 315-point phase-detect AF and 25-point contrast-detect AF system
Sony RX100 VI: 315-point phase-detect AF and 25-point contrast-detect AF system
Sony RX100 VII: 357-point phase-detect AF and 425-point contrast-detect AF system

The RX100 V and RX100 VI's AF system is a considerable step-up from those in its predecessors, with 315 phase-detect AF points working with 25 contrast-detect AF points. The RX100 VII goes further still.

The RX100 V was the first camera in the range to feature on-sensor phase-detect AF, and this continued on to the RX100 Mark VI. This is a 315-point array with wide coverage across 65% of the frame, and this works with the same 25-point contrast-detect AF system that features in the previous two models.

The RX100 VII takes a further step forward, though with a new 357-point phase-detect AF and 425-point contrast-detect AF system which Sony says is its fastest yet, offering a 0.02-sec 'acquisition time' and a newly-optimised lens control.

The new AF system uses technology taken from Sony's flagship A9 pro sports camera and is one of the single biggest distinguishing features between the RX100 VII and its predecessor the RX100 VI. It brings Sony's Real-time Tracking and Real-time Eye AF capabilities, previously seen only on the company's mirrorless models, via new AI tracking technologies.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Burst shooting (fps)

Sony RX100 III: 10fps (burst depth unknown)
Sony RX100 IV: 16fps (burst depth unknown)
Sony RX100 V: 24fps with AF and AE for up to 150 JPEGs
Sony RX100 VI: 24fps with AF and AE for up to 233 JPEGs
Sony RX100 VII: 20fps (burst depth unknown), 90fps in Single Burst mode

The RX100 V and VI's 24fps burst mode makes these the clear favourites for action shooters, but the RX100 VII goes faster still (much faster) in its new Single Burst mode.

All five cameras are capable of capturing fast-moving action, although the difference in burst rates is significant.

The RX100 VI offers a staggering 24fps burst shooting at full resolution, with full-time phase-detect AF and AE, for up to 223 JPEGs. The RX10 V manages much the same, but only to 150 frames.

Interestingly, this drops to 20fps in the RX100 VII, though this model does now boast blackout-free viewing. Crucially, it also has an ultra fast Single Burst mode with a maximum speed of 90fps, so if high-speed motion capture is your thing, then this is another advantage of the RX100 VII over its predecessors.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Viewfinder and LCD

RX100 III: 3in tilting LCD, 1.229m dots; EVF with 0.59x mag. and 1.44m dots
RX100 IV: 3in tilting LCD, 1.229m dots; EVF with 0.59x mag. and 2.36m dots
RX100 V: 3in tilting LCD, 1.229m dots; EVF with 0.59x mag. and 2.36m dots
RX100 VI: 3in tilting touchscreen, 921k dots; EVF with 0.59x mag. and 2.36m dots
RX100 VII: 3in tilting touchscreen, 921k dots; EVF with 0.59x mag. and 2.36m dots

All five models feature built-in electronic viewfinders that offer 100% coverage of the scene. The only main difference here is that the RX100 III's viewfinder has a resolution of 1.44million dots, whereas the three newer cameras have improved 2.359 million-dot panels.

The RX100 IV, RX100 V (pictured), RX100 VI and RX100 VII have 2.36million-dot viewfinder panels, whereas the RX100 III has a 1.44million-dot panel

One smaller change is that, from the RX100 VI on, there's no need to pull the viewfinder out towards you once you pop it up before you start using it, as it all conveniently happens in one action.

The RX100 Mark VI's viewfinder doesn't require you to pull it back once you pop it up, as is the case on the other models. It all happens at once

All five models also have a similar LCD screen that tilts 180° upwards – i.e. all the way around to face the front – although the RX100 VI and RX100 VII are the only models to offer a touchscreen, which is largely used for selecting the focus point rather than navigating the menus.

Furthermore, while the screens on the other three cameras tilt 45° downwards, the display on the RX100 VI and later can be adjusted 90° downwards. The resolution, however, is a little lower, which appears to be down to the fact that they use a standard RGB panel rather than the Sony WhiteMagic RGBW-type panel used on the others.

The RX100 III, RX100 IV and RX100 V LCDs all have a similar tilting mechanism, although the RX100 Mark VI's and VII's (above) is a little more flexible – and it's a touchscreen

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Build and design

RX100 III: 290g (inc. battery and card); 102 x 58 x 41mm
RX100 IV: 298g (inc. battery and card); 102 x 58 x 41mm
RX100 V: 299g (inc. battery and card); 102 x 58 x 41mm
RX100 VI: 301g (inc. battery and card); 102 x 58 x 43 mm
RX100 VII: 302g (inc. battery and card); 102 x 58 x 43 mm

The four models share the same dimensions, and almost match each other for weight too. Pictured here is the RX100 IV

There's very little to split these five cameras in terms of build and design.

The tough, aluminium bodies have an identical control layout, with no discernible difference in size nor weight between them. The fact that all four lack a grip of any sort doesn't sit well with everyone, but optional grips do exist for the benefit of those who fall into this camp.

Given that the only real difference between these is the Roman numerals after the RX100 symbol, this is clearly a design Sony believes in.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Other features

Wi-Fi and NFC is built into all five models. Pictured above is the RX100 V

Once again, we're looking more at similarities than differences when it comes to features.

All four have Wi-Fi and NFC connectivity, and all three lack Bluetooth and GPS. Time-lapse shooting isn't possible on any of the three straight out of the box, although a paid-for app that enables this is available through Sony's PlayMemories store.

If your camera doesn't have the feature you want, you may be able to download it from the PlayMemories store

The RX100 III is the only one of the five that does not have an option to set the minimum shutter speed when using Auto ISO, a useful feature that's included in the others.

The fastest shutter speeds vary between the cameras too. You’re limited to a maximum 1/2000sec with the RX100 III, but the later models each offer a maximum shutter speed of 1/32,000sec.

HDMI and USB ports feature on all four later models. Pictured above is the RX100 VII (Image credit: Sony)

All feature a built-in flash, HDMI and USB ports, and a single card slot that accepts SD, SDHC and SDXC memory cards (and Sony's own MemoryStick format). There's no hotshoe on any of these three – a feature dropped after the RX100 II – so it's not possible to physically mount any accessories on top of any of these cameras.

Sony RX100 III vs RX100 IV vs RX100 V vs RX100 VI vs RX100 VII: Battery life

RX100 III: NP-BX1 battery, 320 shots (LCD)
RX100 IV: NP-BX1 battery, 280 shots (LCD); 230 shots (Viewfinder)
RX100 V: NP-BX1 battery, 220 shots (LCD); 210 shots (Viewfinder)
RX100 VI: NP-BX1 battery, 240 shots (LCD); 220 shots (Viewfinder)
RX100 VII: NP-BX1 battery, 260 shots (LCD); 240 shots (Viewfinder)

All the cameras use the same NP-BX1 battery, but battery life varies nonetheless

It seems as though one downside of certain new features introduced with successive models is their hunger for power.

All three use the same NP-BX1 battery unit, but the older RX100 III has the best battery life of the three, with 320 shots per charge (when using the LCD). This is fairly respectable for such a small camera, and the 280-shot battery life of the RX100 IV isn't too far behind, although this figure drops to just 220 frames on the RX100 V. Sony did, however, manage to boost this back to 240 frames on the RX100 VI and 260 frames on the RX100 VII.

If you think this might be an issue, you may wish to either invest in another battery or carry a powerbank with you so you can recharge the battery, inside the camera, while on the move.

Verdict

Sony clearly found a formula that worked with the original Cyber-Shot RX100, and the following iterations adhere to a very similar core feature set.

Each version has been tweaked, with new features added (and, on occasion, removed) that continually make the cameras in the RX100 series among the most compelling on the market.

In these latest five versions, the changes have mainly reflected Sony’s innovations in video, sensor design, autofocus and processing power.

The RX100 VI is the first RX100 model to offer the new, extended 8x zoom range, not to mention high-speed 24fps continuous shooting. The RX100 VII takes the autofocus and burst modes to new levels, but with a substantial increase in price for features many of us might not be looking for in a camera of this type.

If stills photography is your thing, and you don't imagine shooting too much action, there's little reason to buy the later models, save for the bigger zoom range on the RX100 VI and later. Videographers may be more interested in the RX100 VII, which is the first of these cameras to include a microphone socket – a feature many video shooters might consider long overdue.

All five are very capable for cameras of their kind, and well worthy of the enthusiast's attention.
