Sony’s RX10 collection has delivered premium picture high quality in a fixed-lens, bridge camera design since its introduction. The fourth version, the RX10 IV ($1,699.99), upgrades the picture sensor to incorporate section detection focus, so it may shoot at as much as 24fps whereas monitoring topics. That is an enormous plus for sports activities and wildlife photographers who need to pack gentle—the digital camera has 600mm attain. It delivers picture high quality that is higher than superzooms with small sensors, and in addition affords greatest at school seize velocity and autofocus. Not everybody wants this sort of energy, nonetheless, and it can save you a couple of hundred with out sacrificing picture high quality by choosing our Editors’ Selection RX10 III. However when you do not thoughts paying some more money for extra velocity, the RX10 IV is definitely worth the premium.


The RX10 IV is sort of bodily equivalent to the RX10 III. It is designed in a bridge model—the physique is comparable in measurement and form to an SLR, however the lens is integral to the design moderately than interchangeable. It measures Three.7 by 5.2 by 5.7 inches and weighs 2.Four kilos. The physique is black, with a blended polycarbonate, rubber, and steel exterior and an inside magnesium alloy chassis. It is a weather-sealed design, with sufficient safety to make use of in wet or dusty environments with out fear.

The fastened lens is identical Eight.Eight-220mm (24-600mm equal) f/2.Four-Four design utilized by the RX10 III. It is tied for the longest within the class—the RX10 III makes use of the identical one, and the Canon PowerShot G3 X sports activities a 24-600mm f/2.Eight-5.6 zoom, dimmer and slower to focus than the RX10 IV. To get an thought of the vary of the 24-600mm zoom, check out the picture under: the left half is 24mm and the fitting half is 600mm, a decent shot of the complete moon.

Different superzooms have longer designs, just like the 65x Canon PowerShot SX60 HS. However they use smaller picture sensors and narrower apertures. The RX10 IV makes use of a 1-inch sensor design with a floor space that is 4 instances that of the 1/2.Three-inch designs utilized in extra inexpensive bridge fashions.

Along with the 25x zoom ratio, the lens doubles as a succesful macro. It focuses to 1.2 inches on the extensive angle and to 2.Four ft when zoomed all the way in which in, ok for 1:2 magnification. There is a focus limiter change on the barrel; when turned on it disables macro seize, solely specializing in topics farther than 10 ft (Three meters) away. It speeds focus when photographing distant topics.

Optical stabilization is rated to Four.5 stops by CIPA and I discovered it to work somewhat bit higher than that. I used to be in a position to seize persistently crisp photographs at 1/13-second when capturing at 600mm, higher than 5 stops of compensation. The lens does not have an built-in impartial density filter (included within the shorter zooming RX10 and RX10 II). Should you’re a fan of lengthy publicity pictures, or need to hold your video shutter velocity decrease to keep up a standard shutter angle, you will need to spend money on a set of 72mm ND filters to connect to the entrance of the lens when wanted.

Along with the limiter change, the barrel has a spotlight maintain button; when held in it prevents autofocus from activating. The lens itself has a bodily aperture ring; it may be set from f/2.Four by f/16 in third-stop increments or to show freely with out detents. Knurled steel zoom and guide focus rings are additionally on the barrel. The zoom ring will be set to make minor changes or step zoom to the 24, 28, 35, 50, 70, 85, 100, 135, 200, 300, 400, 500, and 600mm positions.

The main target adjustment toggle rounds out the entrance controls. It may be set to AF-S (Single), AF-A (Auto), AF-C (Steady), or DMF (Direct Handbook Focus) modes. AF-A switches between single and steady focus based mostly on the scene, and DMF lets you override autofocus at any time utilizing the guide focus ring.

Up prime, beginning on the left, is the Mode dial. It turns freely, with none form of locking mechanism. The new shoe is centered behind the lens and pop-up flash; you will need to take away the lens hood when capturing at 35mm or wider with the flash, because the hood can create a shadow on the backside of your picture.

The mechanical flash launch is simply to the fitting, in a row of buttons that additionally contains the highest LCD backlight management, and the programmable C1 and C2 buttons. Behind the row you will discover the monochrome info LCD and a devoted EV adjustment dial with third-stop changes from -Three to +Three EV. The shutter launch (threaded so you need to use a mechanical launch cable), zoom rocker, and On/Off change are on the prime of the handgrip.

The Menu button is on the prime left nook of the rear plate, to the left of the EVF eyecup. Report and the rear management wheel are to the fitting of the EVF. The AE-L and Fn buttons are slightly below the wheel, in between the LCD and thumb relaxation, and there is a flat command dial with a middle button and 4 directional press controls under the 2 buttons. Play and Delete/C3 buttons spherical out the rear controls, under the flat dial.

All the C buttons are programmable, as are the fitting, down, and left directional presses on the flat command dial. Urgent Fn launches an on-screen overlay menu, additionally customizable, with extra management choices. Sony’s menu system is sort of intensive, and never completely organized, so it’s value it to spend a while organising the digital camera to customise its controls and Fn menu to fit your wants. There’s additionally a customizable My Menu web page, a very good place to place generally used capabilities so you do not have to scroll by dozens of menu pages to seek out the one you need to regulate.

The LCD is a Three-inch, 1,440k-dot panel with contact assist. It is vibrant and sharp, and tilts up or down, but it surely does not swing out from the physique or face all the way in which ahead. That is a disgrace when you think about how good of a video digital camera the RX10 IV is.

Contact performance can be restricted. You possibly can faucet to set a spotlight level, however you’ll be able to’t navigate menus by way of contact. Sony does embody Contact Pad focus adjustment. When the digital camera is to your eye you’ll be able to slide your finger throughout the LCD to maneuver the energetic focus level. It really works, however not in addition to a devoted focus management.

Sony Cyber-shot DSC-RX10 IV : Sample Image

The digital viewfinder is large, vibrant, and sharp. It boasts a zero.7x magnification issue, an OLED design, and a 2,359k-dot decision. There’s a watch sensor, so it activates and off routinely as you carry the digital camera to your eye, and Sony has eradicated the sensitivity problem that plagued the primary two RX10 fashions; it is troublesome to by accident set off the attention sensor together with your physique, and it does not work in any respect when the display screen is tilted out.

Connectivity and Energy

The RX10 IV contains Bluetooth, NFC, and Wi-Fi. It might probably pair with Android and iOS gadgets with a purpose to switch photographs or movies or for distant management. Picture transfers are fast—the digital camera resizes photographs to 2MP to hurry issues up—however video switch, particularly when you’re capturing at 4K, can take some time, even when utilizing a top-end smartphone.

Sony Cyber-shot DSC-RX10 IV : Sample Image

Bodily connections embody the multi-interface sizzling shoe, which might accommodate an exterior flash or Sony’s XLR audio adapter, Three.5mm headphone and microphone jacks, micro HDMI, and micro USB. The battery prices in-camera by way of USB; Sony does not embody an exterior charger with the RX10, only a cable and a USB-to-AC adapter. The included battery is sweet for about 400 photographs utilizing the rear LCD, 370 photographs with the EVF, or as much as 75 minutes of video per CIPA requirements, which ought to get you thru a full day of capturing. However if you wish to spend money on a spare battery, it is clever to purchase an exterior charger on the identical time—that approach you need to use the RX10 IV as you recharge the spare battery, or cost one in-camera and one out of digital camera on the identical time.

The reminiscence card slot is on the fitting aspect, separate from the bottom-accessible battery compartment. It is a single slot with assist for SD, SDHC, SDXC, and Reminiscence Stick Duo codecs. Its velocity ranking tops out at UHS-I, so you’ll be able to’t reap the benefits of the velocity provided by the most recent ultra-fast UHS-II SD playing cards.

Efficiency and Autofocus

Sony Cyber-shot DSC-RX10 IV : Benchmark TestsAs a result of its lens has to increase to start out capturing, the RX10 IV is somewhat sluggish to energy on, focus, and seize a picture—it takes about 2.Three seconds to take action. That is par for the course for a superzoom digital camera. However its autofocus system could be very speedy, locking on virtually immediately when capturing in vibrant gentle, and managing a zero.Four-second focus lock in very dim circumstances.

Sony Cyber-shot DSC-RX10 IV : Sample Image

And it is the autofocus system, and burst fee, that actually set the IV other than the RX10 III. When you can shoot JPGs at 14fps and Uncooked photographs at 8fps with the III, the IV ups the burst fee to a staggering 24fps, even in Uncooked format, and provides on-sensor section detection for higher topic monitoring.

Capturing fast-moving motion—a soccer match for instance—is one thing you are able to do extra successfully with the RX10 IV than with the III, even when capturing at 24fps is an overkill for a lot of topics—and might replenish your reminiscence card extra shortly. You possibly can nonetheless reap the benefits of the sooner focus system when dialing the burst fee all the way down to a extra affordable 10fps by setting it to medium as an alternative of excessive.

Sony Cyber-shot DSC-RX10 IV : Sample Image

The capturing buffer is massive sufficient to carry 105 Uncooked+JPG, 106 Uncooked, or 228 JPG photographs when capturing at 24fps. Clearing it to a reminiscence card does take a while—70, 50, and 75 seconds respectively, when paired with the quickest UHS-I card we had, rated at 95MBps. I want the slot was UHS-II, which may lower buffer clear instances by a 3rd, as you’ll be able to’t begin recording a video if there are any photographs left within the nonetheless buffer.

You will have some totally different choices when it comes to focus space. The default setting is Huge, which covers about 65 % of the sensor with section and distinction detection factors. You possibly can couple this with EyeAF (you will want to show it on within the menu; I mapped it to the rear middle button to match the operation of Sony’s a7 and a9 mirrorless digital camera household) for the perfect outcomes when photographing folks. It’ll attempt to detect and focus in your topic’s eyes, and falls again to plain face detection if it may’t determine a watch.

Sony Cyber-shot DSC-RX10 IV : Sample Image

You possibly can override the Huge space by tapping on the rear display screen; it modifications the main target mode to Versatile Spot, which solely seems for focus in a small space of the body. You may as well set the digital camera to make use of the Versatile Spot always (with Small, Medium, and Massive choices out there for the spot measurement), Heart level solely focus, or Lock On Versatile Spot. The latter is simply out there in Steady focus mode; it identifies the topic beneath the spot you choose and tracks it because it strikes by the body. In any focus mode, small inexperienced dots dance within the viewfinder to let you already know what the digital camera is specializing in.

I have a tendency to make use of the Huge focus space when capturing with the RX10 IV, together with EyeAF when photographing folks. The digital camera does a very good job selecting the main target level, however in fact there are occasions if you need to management it fully. Utilizing the Contact Pad AF operate to maneuver the main target space round works, however I do not assume it is as responsive correctly. It might probably take a couple of swipes to maneuver the purpose from the fitting to left aspect of the body. You possibly can choose to set it Absolute positioning, which signifies that tapping to the left of the contact space (configurable by way of the menu) strikes the purpose to the left instantly, however I discovered that much more irritating to make use of than the default Relative mode.

Sony Cyber-shot DSC-RX10 IV : Sample Image

I would like to see Sony add a devoted focus joystick management to the physique, because it has with its newest full-frame mirrorless cameras. It will go a protracted approach to bettering this one side of operation. Maybe we’ll see it within the inevitable RX10 V.

There’s additionally a little bit of a downside for devoted sports activities shooters, relying on which sport you cowl. Basketball photographers, for instance, will possible discover the facility zoom lens to be a little bit of a downer. Even when set to its sooner operation mode, it takes for much longer to regulate than you’d with a mechanical zoom SLR lens. Should you’re sitting beneath the web and a participant is driving towards you for a layup or dunk, it is more durable to maintain them tightly framed than it might be with an SLR lens—you are higher off capturing a bit extensive and cropping later in order for you the entire sequence. Preserve this in thoughts if you should change the focal size shortly and recurrently when capturing sports activities or related motion.

Picture High quality

The 20MP 1-inch picture sensor is about 4 instances the bodily measurement of the sensors utilized by most superzoom cameras. It measures 13.2 by Eight.8mm, for a floor space of 116mm2. To place it in additional perspective, that is a couple of third of the dimensions of the APS-C sensor you discover in shopper SLRs.

Sony Cyber-shot DSC-RX10 IV : Sample Image

I used Imatest to investigate its efficiency when capturing photographs at varied ISO settings. The RX10 IV has a local vary of ISO 100 by 12800, with low prolonged settings out there at ISO 64 and 80. ISO 25600 is supported, however solely when utilizing Multi-Body seize and mixing.

When capturing JPGs at default settings the digital camera retains noise beneath 1.5 % by ISO 3200, about what we count on from this sensor sort—the 20MP 1-inch design is utilized in many premium compact fashions, together with competing choices from Canon and Panasonic. However solely Sony has this stacked design with on-sensor section detection.

Sony Cyber-shot DSC-RX10 IV : Sample Image

There may be actually some noise discount happening to web these outcomes. To my eye, photographs shot by ISO 800 are completely crisp, with no proof of noise discount or grain. At ISO 1600 the very tiniest particulars of our take a look at picture lose some crispness, however are nonetheless distinct. There’s some seen smudging at ISO 3200, so these strains begin to run collectively a bit. The smudge impact is extra pronounced at ISO 6400, however nonetheless effective for internet decision and smaller prints. It offers approach to a extra blurred have a look at the highest customary setting, ISO 12800.

Should you choose to shoot in Uncooked format you will get squeeze extra readability out of pictures at greater ISOs. There’s extra grain in photographs captured at ISO 1600 than with a JPG, however particulars are clearer. That holds true as velocity ramps up; particulars are notably crisper within the ISO 3200 Uncooked picture. Noise cuts into picture high quality at ISO 6400, so that you get a grainier picture with somewhat bit extra element than the JPG, as is the case at ISO 12800.

The RX10 IV has a brighter lens than many different supezooms. It captures extra gentle at each equal angle of view compared with the Canon G3 X (f/2.Eight-5.6) and small sensor SX60 HS (f/Three.Four-6.5). However the lens is not simply vibrant, it is also actually sharp.

At 24mm f/2.Four it scores 2,362 strains per image top on a center-weighted sharpness take a look at. Many of the body meets or exceeds the typical rating, though edges (1,809 strains) fall behind. They nonetheless match the 1,800 strains we need to see at a minimal from a 20MP digital camera, nonetheless. Narrowing the aperture improves edge high quality—they present 1,986 strains at f/2.Eight and a pair of,345 strains at f/Four. The typical additionally improves—2,601 strains at f/2.Eight, 2,925 strains at f/Four, and a pair of,856 strains at f/5.6. After that diffraction units in and limits picture high quality; it is best to keep away from capturing at f/11 (1,852 strains) and f/16 (1,215 strains) when doable.

Sony Cyber-shot DSC-RX10 IV : Sample Image

At 50mm the utmost aperture has narrowed to f/Three.2. Sharpness is robust, 2,803 strains, with edges that are not far behind (2,559 strains). You get a bit extra decision at f/Four (2,912 strains) and f/5.6 (2,836 strains). Picture high quality drops at f/Eight (2,502 strains), f/11, (1,809 strains), and f/16 (1,206 strains).

By 100mm the lens has narrowed to f/Four, however picture high quality does not take a step again. We see 2,839 strains on common, with wonderful efficiency from middle to edge (2,632 strains). There’s not a lot change at f/5.6 (2,843 strains) or f/Eight (2,573 strains), however we see an enormous drop at f/11 (1,768 strains) and f/16 (1,203 strains).

Sony Cyber-shot DSC-RX10 IV : Sample Image

We see very related efficiency at 200mm and 300mm. At f/Four and f/5.6 the lens resolves about 2,800 strains on common with sturdy high quality from edge to edge. Narrowing to f/Eight drops the decision to about 2,500 strains, and we see simply 1,750 at f/11 and 1,200 at f/16.

There is a dip in edge efficiency at 400mm f/Four (1,618 strains), however the common stays superb (2,390 strains). Stopping all the way down to f/5.6 improves the general rating to 2,589 strains, and you continue to get good outcomes at f/Eight (2,334 strains). Skip f/11 (1,682 strains) and f/16 (1,174 strains).

Sony Cyber-shot DSC-RX10 IV : Sample Image

Outcomes aren’t that far off at 500mm. At f/Four the typical rating is 2,433 strains, with higher edge high quality (1,828 strains) than at 400mm. The story is about the identical at f/5.6. At f/Eight we get higher edges (2,037 strains) and a robust common (2,356 strains), earlier than diffraction kills readability at f/11 (1,710 strains) and f/16 (1,145 strains).

Zooming all the way in which in to 600mm does take its toll. At f/Four the lens scores 2,121 strains on common, however edges are weak (1,480 strains). Stopping all the way down to f/5.6 improves the periphery (1,861 strains) and common (2,405 strains). Edges are higher at f/Eight (1,931 strains), however there is a hit on the typical rating (2,241 strains) as middle decision drops a bit. Once more, f/11 (1,549 strains) and f/16 (1,082 strains) are greatest forgotten about.

You do not have to fret about distortion or darkened corners. The RX10 IV applies corrections to each Uncooked and JPG photographs to take away each. Most Uncooked converters will acknowledge the corrections, though it’s possible you’ll be compelled to make them your self when you stray too removed from Lightroom or Capture One.

Sony Cyber-shot DSC-RX10 IV : Sample Image

General the lens is a superb performer, higher than one with a vibrant design and 25x zoom energy has any proper to be. However that is what you count on from a digital camera that prices this a lot. You may get the Canon G3 X for lots much less cash, however its lens does not maintain up as properly when zoomed all the way in which in, nor does it seize as a lot gentle. (And the G3 X is tormented by slower autofocus, making motion photographs troublesome.)


The RX10 collection has all the time been succesful for video, even with the primary mannequin that was launched within the 1080p period. Each iteration since then has supported 4K seize. The IV captures 4K footage at 24 or 30fps, together with your selection of 60 or 100Mbps XAVC S compression. Should you’re proud of 1080p you’ll be able to seize video at 24, 30, 60, or 120fps at bit charges starting from 16Mbps (to save lots of house on the cardboard) by 100Mbps (for very best quality), additionally in XAVC S. There are additionally AVCHD choices out there, though the format is not broadly utilized in 2018.

It is not nearly decision. The RX10 IV provides SLog3 to its laundry listing of image profiles (the RX10 III helps SLog2). Capturing in a log format reduces distinction, so extra dynamic vary is preserved in your video. Nevertheless it requires you to use a coloration grade utilizing software program to make the footage look good—when you’re a professional who is aware of coloration appropriate, you are conversant in the method.

Along with pro-level video profiles, the RX10 IV helps an exterior microphone. Vloggers and journey videographers shall be proud of an on-camera shotgun microphone related by way of Three.5mm. However for extra severe work you should buy Sony’s $499 XLR add-on and join a balanced microphone.

The digital camera also can transcend 120fps when you want slower slow-motion. It has an HFR setting on the Mode dial—Excessive Body Fee. You possibly can set it to report footage at 240, 480, or 960fps and to play again at 24, 30, or 60fps, supplying you with a various vary of decelerate. I am an enormous fan of 240fps at 24fps, a 10x impact. There are a bevy of choices for HFR, together with when to start out the clip and the standard of the seize—the prime quality mode captures 4 seconds of actual life, and the decrease high quality possibility extends that to seven seconds.

All HFR is output at 1080p high quality, however not all 1080p is created equal. The 240fps seems the sharpest, and the 960fps is a bit delicate and in addition cropped. You additionally want a ton of sunshine to shoot at 960fps—the digital camera wants to make use of a minimum of a 1/960-second publicity for every body with a purpose to attain that velocity.

Sony Cyber-shot DSC-RX10 IV : Sample Image

There are a few caveats for utilizing HFR. One, the digital camera must buffer footage earlier than it may begin recording. You can begin the buffering course of properly prematurely of beginning the video, however focus and zoom are locked as soon as the buffering begins. Second, and most annoying, is the period of time that it takes to render the video. In case you are capturing at 240fps and enjoying again at 24fps, a full clip is about 45 seconds—which is how lengthy it takes to save lots of the film file to the cardboard.

The most important draw back to HFR is the period of time it takes to render out a video. After you have captured your sluggish seconds of video you should wait a full 45 seconds whereas the digital camera renders the footage. Should you’re capturing at 960fps you’ll be able to await greater than two and a half minutes for the video to be prepared when capturing in prime quality mode. When it is processing you’ll be able to’t use the digital camera for the rest, though you’ll be able to cancel at any time.

Sony Cyber-shot DSC-RX10 IV : Sample Image

However, for the fitting scene, the impact is definitely worth the wait. And you may all the time shoot at 120fps 1080p in customary mode for a extra modest slow-motion impact with out the stringent necessities of HFR seize.


The Sony Cyber-shot DSC-RX10 IV is probably the most feature-filled, and costliest, variation of the digital camera but. It retains the identical 24-600mm f/2.Four-Four lens because the RX10 III (now priced round $1,400), however provides on-sensor section detection for faster focus and a staggering 24fps burst seize fee, even in Uncooked mode. It goes past what different bridge cameras can do, delivering a zoom vary that covers all however excessive telephoto capturing, 20MP of decision, and the picture high quality of a 1-inch sensor, which is past what smaller sensor cameras can ship.

It wraps all of it up in a tricky, weather-sealed physique, with a crisp EVF and tilting contact LCD. Video options are additionally sturdy, with each crisp 4K seize and excessive slow-motion at 1080p out there. The RX10 IV is the best bridge digital camera cash should purchase.

Nevertheless it takes some huge cash to purchase it. There is not any doubt it’s extra totally featured than the RX10 III, but it surely does not change it in Sony’s lineup. We proceed to suggest the RX10 III to most photographers trying to find a high-end bridge mannequin. It’s greater than sufficient digital camera for many functions, and prices $300 much less. However when you’re not as delicate to cost, or shoot topics the place an improved burst fee and focus system will turn out to be useful—usually sports activities and wildlife—spend the additional cash on the RX10 IV.
