Sony Cyber-shot DSC-RX100 IV with high-speed video and 4K video function

Sony adds a fourth model to its RX100 series with the Cyber-shot DSC-RX100 IV. The IV is the trump card because it films in 4K resolution. The new, fast sensor also enables high-speed videos in full HD at 1,000 fps or 16 continuous shots per second in full sensor resolution of 20 megapixels. The RX100 IV adopts the F1.8 to F2.8 fast 24-70mm lens and the fold-out electronic viewfinder from the RX100 III.

Short evaluation

  • Compact, high-quality housing
  • Fast autofocus
  • Very good image quality up to ISO 1.600
  • Impressive Full HD high-speed video function
  • Very good, albeit time-limited, 4K video function

Cons

  • Quite high price
  • Few display options
  • Somewhat cumbersome WLAN connection

However, the resolution of the OLED viewfinder increases from 1.44 to 2.36 million pixels. The rear 7.5cm screen can still be folded down and up, the latter even so far that the monitor is suitable for Selfies. Thanks to WLAN and NFC, recordings can be sent directly to a mobile device, and the RX100 IV can be remotely controlled via an app. Apps are also available directly for the camera to extend its functions. Sony offers both free and paid applications called “Camera Apps”.

But back to the heart of the matter, the 1″ BSI sensor: it still resolves 20 megapixels, but uses new technologies: The electronic circuits are no longer located at the edge of the sensor, but rather behind it over a large area, which permits more powerful circuits. In addition, these are now made of copper instead of aluminium, which allows a higher packing density and speed. Last but not least, the sensor has an integrated DRAM as buffer memory and achieves a 5 times higher data transfer rate than the old sensor. This allows an amazing 16 continuous shots per second at full resolution. Finally, the RX100 series is also capable of 4K video recording, but in contrast to the RX10 II, which is presented in parallel and equipped with the same sensor, the RX100 IV films in 4K only about five minutes at a time instead of 29 minutes. Ultimately, this is due to the heat generated during processing, which is not so easily dissipated in the small housing. However, depending on the outside temperature, several 5-minute clips can be made in direct succession.

As the first model in the RX100 series, the Sony Cyber-shot DSC-RX100 IV is capable of 4K video recording, but only for five minutes at a time. High-speed videos in full HD resolution makes them even with 1,000 fps. [Photo: Sony]

The RX100 IV even records high-speed videos with up to 1,000 frames per second, but 250 and 500 frames per second are also possible. Depending on the frame rate, two or four seconds can be recorded at different resolutions, and the recording button can be used as the start or end button. Playback takes place in 25p or 50p, i.e. with up to 40x slow motion. The new sensor also comes with an optional electronic shutter that allows shutter speeds of up to 1/32,000 second. Thanks to “Anti Distortion”, the electronic shutter should have no rolling shutter effect and is therefore also suitable for rapidly moving motifs or camera pans. The short exposure time allows the high light intensity to be used for exposure even in sunlight.

Although the Sony Cyber-shot DSC-RX100 IV has been on the market for a while, the slight differences to the RX100 III at a hefty surcharge didn’t necessarily make the test a priority for our editors. But now we got our hands on them and the new functions are quite impressive. Of course, the laboratory test is not missing either and proves once again how leading Sony is with the 1″ sensor cameras.

Ergonomics and workmanship

The Sony DSC-RX100 IV is surprisingly small for its relatively large 1″ sensor (13.2 x 8.8 millimetres), at least for a compact camera, and its fast lens. The case measures only ten times six times 2.5 centimeters; in addition, there is the lens that is 1.5 centimeters outstanding, which extends by another almost four centimeters when switched on. Interestingly, the lens becomes shorter again when zooming from 24 to 70 millimetres (35mm equivalent). The case has a modern and simple design, the black anodized metal has a high-quality touch. At almost 300 grams, the RX100 IV is certainly not a lightweight, because of its small size it looks almost heavier than it is, which underlines the high-quality impression. A full 1,150 euros (RRP) is required from Sony for the compact camera. Despite this proud price, there is no weather protection at all on the case. The high price is probably mainly due to the modern, leading technology inside, more on that later.

The 300 gram Sony DSC-RX100 IV is an extremely compact companion with a relatively large 1″ sensor (13.2 x 8.8 mm) for compact cameras.

As nice as the small housing is designed and as little space the camera takes away in the bag, so you can almost always have it with you: This minimalism is not good for ergonomics. Due to its size or “small” size alone, one hardly knows where to leave one’s fingers. The thumb finds a small rubberized surface on the back, where it finds quite safe hold. This applies less to the two or a maximum of three fingers on the front of the case, which is not only smooth, but also has no contours or handle. The left hand also desperately looks for support, as the display reaches to the right edge, the lens is too narrow to hold and the top of the camera accommodates two pop-up devices.

If you still have to compromise on ergonomics, the RX100 IV shines with its display, viewfinder and many buttons. With 7.5 centimeters, the screen not only offers a large diagonal, especially in view of the camera size, but also has a very fine resolution of 1.23 million pixels. Above all, the brightness is very good thanks to the additional “white” subpixels, even if situations can still be found in which brightness and contrast are no longer sufficient. In addition, the screen can be folded down 45 degrees and up 180 degrees. This offers a lot of flexibility, even if a small part of the screen is covered by the case of the Selfie. Unfortunately a touch screen functionality is missing.

The ingenious pop-up viewfinder is already known from the RX100 III, which Sony has further improved. Mechanically unlocked, the viewfinder rushes upwards, and the eyepiece must also be pulled out. The viewfinder offers not only diopter correction, but also an eye sensor for automatic switching. With 0.6x magnification compared to 35mm, the viewfinder is even decently large. Due to its design, however, the eyepiece does not offer any protection against light incident from the side between the eye and the viewfinder. In addition, eyeglass wearers are unable to see the viewfinder because the exit pupil is too small, and the viewfinder is clearly shaded from the side. In contrast, Sony was even able to significantly increase the resolution from 1.44 to 2.36 million pixels. An OLED is still used, which also flickers slightly in very bright image areas.

Sony had to be economical with controls because of the small case size, but the RX100 IV offers the essentials even for ambitious photographers. There is an operating ring on the lens and an additional thumbwheel so that two functions can be controlled independently of each other. Depending on the mode, the lens ring in particular can take on a wide variety of functions and can also be used, for example, as a zoom ring as an alternative to the zoom rocker, if desired in stages. In addition, there is the control pad with central confirmation key and four additional operating keys, some of which can be assigned individually. Sony remains true to its menu, so as a connoisseur of the brand, you will quickly find your way around. The menu, which is divided into tabs, does away with the annoying vertical scrolling, but due to the many functions, the clarity is still limited.

With a maximum aperture of F1.8 to F2.8, the Sony DSC-RX100 IV offers a fairly fast lens that covers an angle of view like a 24-70mm 35mm lens.

Clever: The Sony DSC-RX100 IV offers a foldable viewfinder that delivers a relatively large and, above all, finely resolved image. Only spectacle wearers have some problems with the small exit pupil.

The small housing, on the other hand, is extremely economical with interfaces. There is only one Micro-HDMI and one Micro-USB interface. The latter also serves to charge the replaceable lithium-ion battery, which provides juice for a good 300 photos. However, if you use the 4K or HFR video functions, you will notice a significant increase in battery consumption with accompanying heat development on the right side of the case, which sometimes even requires cooling breaks. In any case, the USB interface is not choosy whether the energy comes from the original power supply or from a third-party device, such as a smartphone charger. Unfortunately, the tripod thread on the underside of the case is located outside the optical axis and right next to the battery and memory card compartment. In the beginning, the RX 100 IV proved to be extremely selective with memory cards in the test. Only SDXC cards (available from 64 GB), UHS-I and UHS Speed Class 3 compliant, were sufficient for the camera to record 4K video. Even with an appropriate card, the camera sometimes refused to record video. The RX100 IV was not satisfied with a 16 GByte SDHC memory card, which also fulfils the UHS Speed Class 3. Fortunately, this changed with the firmware update 1.30 that Sony released during our test. After that, five minutes of 4K video recordings were also possible with the 16GB card. Unfortunately, the RX100 IV doesn’t film any longer in this resolution anyway.

Equipment

The Sony RX100 IV offers the necessary range of functions for all user groups. If the camera is to accept all settings automatically, it does so without complaint in auto mode. You can even choose to select normal modes only or those that reduce noise or shake by taking multiple shots, for example. In panorama mode, wide-screen shots are just as successful as in portrait mode, and the scene modes allow the user to specify the subject for the camera. Despite the automatic mode, the RX100 IV offers a number of intervention options, such as continuous shooting mode or manual focusing. In addition, a simple option selection allows, for example, the influence on background blur or colors, filter effects such as monochrome or toy camera are also available.

Ambitious users will be pleased with the classic creative programs in which they can influence the image effect by means of aperture and exposure time. The Sony even offers a swing-in neutral density filter. The darkening by a little more than two f-stops allows the use of a wide open f-stop even in brighter surroundings. In addition to the classic exposure programs P, A, S and M, three individually assignable memory locations are also available for preferred shooting settings.

As a compact camera, the Sony RX100 IV operates with a central shutter that only allows shutter speeds of up to 1/2,000 seconds. These are also available for flash sync. However, the integrated flash with a guide number of about 3.5 is quite weak even for a compact camera. Sony is fully committed to high speed and good image quality, even at higher sensitivities, which still gives you decent flash ranges. The Sony offers the necessary flash programs like a long time synchronization, the flash at the end of the exposure or a flash exposure correction, but external flashes are neither supported by flash shoe – which is missing – nor by wireless TTL. For flash enthusiasts the RX100 IV is definitely the wrong choice.

The case of the Sony DSC-RX100 IV is quite flat with 2.5 centimeters. The lens barrel applies 1.5 centimeters, when switched on it extends by a further four centimeters.

The tripod thread of the Sony DSC-RX100 IV is not only located outside the optical axis, but also directly next to the battery and memory card compartment. The Micro-USB interface, however, not only allows the memory card to be read out but also the battery to be charged.

If you find 1/2,000 seconds too long for your photos, you can use the electronic shutter, which the IV offers for the first time within the RX100 series. This enables short exposure times of up to 1/32,000 second. Instead of a quiet click, no shutter noise can be heard at all. Unlike some other cameras, the Sony also allows longer exposure times – up to 30 seconds – with electronic shutter. However, the rolling shutter effect has to be taken into account, especially for pans or fast motifs, which is less pronounced in the Sony, thanks to the new sensor, but doesn’t fail completely.

In continuous shooting mode, Sony promises up to 16 frames per second, which we couldn’t achieve by a long shot. In JPEG we measured a maximum of almost ten frames per second, in Raw it was even only 7.6. Both are not bad values, but far away from the promise. After all, the recording series last quite a long time thanks to the large buffer memory. After that you have to wait a few seconds to save the file. Unfortunately, the Sony doesn’t actively display this, but when pressing the menu button, it simply doesn’t open or when trying to display the image, there is an error message. If one opens the memory card compartment, one discovers a small red writing light. But why Sony has hidden them so well is a mystery to us, especially as the camera blocks some functions during the writing process. After all, further recordings are possible as long as there is free space in the buffer memory.

Even if the continuous shooting mode is not as fast as promised, the autofocus and shutter release delay are fast. With just 10 to 30 milliseconds (0.01 to 0.03 seconds) of shutter delay, the Sony RX 100 IV captures the image virtually immediately after the shutter button is pressed. The autofocus also works very fast with 0.15 to 0.18 seconds, but this is also due to the fact that even in AF-S mode the RX100 IV adjusts the focus on the subject before shooting and only fine-tunes it briefly when the shutter-release button is pressed.

The video capabilities of the RX100 IV are impressive – but due to the small size of the case they are sometimes very limited. The heat development during a video recording is not insignificant, even if you film “only” in Full-HD. In 4K resolution, which the RX100 IV is the first camera in this series to offer, the recording length is limited to five minutes from the outset. However, the quality of the videos, especially at the highest quality setting, knows how to impress. Autofocus and exposure are smoothly and accurately tracked by the Sony, whereby the exposure can also be controlled semi-automatically or manually if desired. The zoom works slower and almost noiselessly, the autofocus is not audible. The optical image stabilizer works the loudest, but is not annoying. If you want, you can record up to 1,000 frames per second in HFR mode and playback them up to 40 times slower. However, the recording length is limited to two to four seconds, depending on the mode. So you should adjust the shot well to the action motif. The resolution of the high-speed videos is apparently extremely good with Full-HD as the output resolution. Depending on the frame rate and recording time, however, the resolution is upscaled in some cases by significantly lower resolutions. Depending on the frame rate, the recording resolution is between 800 x 270 pixels at 1,000 frames per second and 1,824 x 1,026 pixels at 250 frames per second.

After installing firmware 1.30, the Sony DSC-RX100 IV is much less picky about the memory card.

The Sony DSC-RX100 IV offers only a micro-HDMI and a micro-USB interface.

The further range of functions is limited to standard functions such as bracketing, a multiple self-timer, HDR shots or the dynamic expansion DRO. Especially after recording, the RX100 IV offers hardly any image processing possibilities. Instead, Sony fully relies on the Camera Apps, which extend the range of functions partly free of charge and partly for a fee. What you get for free from other manufacturers, you have to pay additionally for this expensive camera. After all, there are also some apps with functions that other manufacturers do not offer. A completely new feature is even an app that circulates on the Internet and removes the annoying 30-minute limit for videos. For the RX100 IV, however, this is rather uninteresting due to the heat generation. The fact that Sony even outsources the WLAN remote control of the camera to an app is useful if there are function updates, but also cumbersome for the user. Details can be found in our photo tip in the further links.

Picture quality

The Sony RX100 once set new standards in compact camera image quality. Of course, the RX100 IV was not inferior in any way.

It’s not surprising that the F1.8-2.8 fast 24-70mm lens (all focal lengths according to 35mm) with all apertures and focal lengths on the 20 megapixel sensor offers sufficiently sharp images from the center to the edge of the picture for prints of 20 x 30 centimeters in size. The edge darkening remains always small with a maximum of 36 percent (0.6 f-stops), also the distortion plays no role. Even color fringes take place at a very low level, so that a digital correction of optical errors must be assumed that does an excellent job. The measurement of the actual resolution at 50 percent contrast (MTF50) shows the strengths and weaknesses of the lens. It resolves up to 60 line pairs per millimeter (lp/mm, 35mm equivalent), which is very good for a sensor with a physical resolution of 20 megapixels. This maximum is reached in wide angle at F4. With an open aperture, the lens has a slightly lower wide-angle resolution, but also a very good resolution of well over 50 lp/mm. Starting at F5.6, diffraction already sets in, which is especially noticeable at the smallest aperture F11 and presses the resolution to 47 lp/mm. At the edge of the image, the lens always resolves over 30 lp/mm at wide-angle, but never over 40 lp/mm, thus showing a visible edge drop in larger prints.

When zooming, the edge resolution increases, but the resolution in the image center also decreases. The more you zoom, the more even the resolution becomes. With a medium focal length, diffraction is needed to press the resolution to below 50 lp/mm at apertures smaller than F8. The maximum of 54 lp/mm is at F4. With the exception of F11, the edge resolution is always above 40 lp/mm with a maximum of 43 lp/mm at F5.6. In telescopic position, the lens must be stopped down to F5.6 to raise the resolution curve starting at 45 lp/mm above the 50 lp/mm mark. At F5.6, the maximum is reached at 52 lp/mm; diffraction sets in at further dimming. At the edge of the image, both F2.8 and F5.6 achieve 46 lp/mm each in the telescopic position, which represents the maximum edge resolution for the entire lens.

Thanks to the NFC chip, the Sony DSC-RX100 IV is relatively easy to connect to compatible devices. Thanks to WLAN, this also works without NFC.

From the top of the Sony DSC-RX100 IV not only the viewfinder can be folded out, but also a small flash. But even for a compact camera, this one is very weak-chested. Luminous intensity and high ISO compensate for this.

So the lens is quite a sight to behold. The resolution is even slightly higher than that of the RX100 III, but the IV also shows slightly stronger sharpness artifacts. Thus, the lens for a compact camera zoom sometimes delivers very good values. This can also be said of the 1″ sensor. The signal-to-noise ratio is just over 40 dB up to ISO 200 and remains within an acceptable range of over 35 dB up to ISO 1,600. Only at ISO 3.200 is it slightly lower. The noise is fine-grained and only becomes slightly visible from ISO 3.200 in the form of brightness noise, whereas color noise plays practically no role. The texture sharpness shows images rich in detail up to ISO 1,600. Even at ISO 3,200 and 6,400, the Sony still delivers enough detail, even though the images are a bit softer here.

The input dynamics even reach up to ISO 3.200 at a high level of over ten f-stops, and at ISO 125 the value of eleven f-stops is exceeded. The tonal value curve runs divided for high-contrast midtones. Up to ISO 800, the RX100 IV shows a very good output tonal range with over 192 of 256 possible brightness levels. With higher sensitivities, the value begins to decrease more strongly, from ISO 3.200 the tonal range is only sufficient with less than 128 steps. The colour accuracy is moderate, some colour tones suffer above all from a clearly turned up saturation. This does not detract from the variety of colours, up to and including ISO 1,600 Sony differentiates more than four million colour tones.

The Sony RX100 IV doesn’t show the most neutral colors, but it does inspire with beautiful JPEG images that don’t need any further post-processing. Those who like to “put their hands” on the image development themselves will anyway be better off resorting to the raw data format. In any case, there’s hardly anything left to optimize at the JPEGs and Sony gets a better image quality from the 1″ sensor than most of its competitors. Particularly at higher sensitivities such as ISO 800 and 1,600, the images appear neither soft rinsed nor noisy. Even at ISO 3,200, image quality doesn’t deteriorate too much.

Bottom line

The Sony DSC-RX100 IV is not only an extremely compact, but also a very good camera. The technology inside is the finest, while the case also has a quality of workmanship appropriate to the price. The ergonomics suffer somewhat from the compactness, but the range of functions does not. Especially the performance of the camera during autofocus, the speed of the continuous shooting and the videos is impressive. But the RX100 IV also has a few downsides, such as the camera apps that are somewhat complicated or annoying for some functions (instead of implementing the useful functions directly), the weak-chested flash without external control or the somewhat fiddly viewfinder. However, the Sony RX100 IV scores most in image quality, where it continues to raise the bar for 1″ sensor cameras. Up to ISO 1,600, it does not even need to shy away from comparison with an MFT or APS-C camera. It should also be mentioned that the same camera is available with less video functionality and a lower continuous shooting rate as well as a slightly lower viewfinder resolution at a significantly lower price. This makes the Sony DSC-RX100 III the biggest competitor for the RX100 IV.

Firmware update 2.00 for the Sony DSC-RX100 IV: For better underwater recordings

Sony has released a new firmware version 2.00 for each of the three RX100 models III, IV and V. The new firmware version will be available at the end of this year. The new features are identical: There is an “Underwater Auto” mode for white balance and the possibility to switch off the flash even when the camera is unfolded. Furthermore, the camera should function more stable overall. The updates are aimed at users of the new URX100A underwater housing, into which each of the previous five generations of the RX100 fits.

I am Peter Dench. Digital Photographer, born in London 1972, currently living in Deerfield, near Chicago. I have numerous photography expositions and also working in model photography. In this website, PhotoPoint, I usually review cameras provided by local dealers in Illinois and by the manufacturers. Sometimes I, Peter Dench, review lenses too, but only when I have a suitable camera for them. Please let me know in the comments if I can improve any of these articles.
