Aesthetically, the RX10 is similar to a digital SLR in nearly every way. There's a pronounced grip, a top-mounted monochrome LCD, a pop-up flash, a hot shoe (in this case, Sony's Multi Interface Shoe), dedicated mode and exposure-compensation dials, an XGA OLED viewfinder, a 3-inch 1.23M-dot LCD that tilts up 84 degrees and down 43 degrees and a relatively large SLR-like lens up front. Internally, however, the RX10 is akin to its smaller counterparts, the RX1 and RX100 Mark II. In fact, the 10 features the same 20.2-megapixel 1-inch BSI CMOS sensor as that latter model, which, while still quite large, is smaller than the APS-C and 35mm chips in conventional DSLRs. It also includes Sony's powerful new BIONZ X processor, which can also be found in the Alpha 7 and 7R, along with Sony's recently announced A5000.
But back to that lens. The 24-200mm Zeiss Vario-Sonnar T* optic is undoubtedly the star of the show, thanks in no small part to its constant f/2.8 aperture. Why is that significant, you ask? Most zoom lenses, especially those permanently attached to a camera, include variable aperture lenses. While some may let you shoot at f/2.8 at the widest focal length (24mm in this case), you won't find many point-and-shoots that offer that same aperture at the tele end as well. Typically, a lower-end lens supports apertures no larger than f/5.6 or f/6.3 at 200mm, and with f/2.8 available instead, you'll be able to snap much sharper images in low light, or shots with creamy bokeh (shallow depth of field) during the day. You still have f/5.6 (all the way up to f/16) at your disposal, of course, directly accessible using the dedicated ring dial around the base of the lens, should you be after different imaging effects, instead.
We'll speak more to the camera controls in the next section, but there are still plenty more hardware components to explore, too. Sony's put a lot of emphasis on connectivity with the RX10. On the audio front, you'll find headphone and mic jacks, stereo microphones up top and compatibility with Sony's advanced audio accessories using the accessory port that doubles as a hot shoe -- for mounting wireless receivers and shotgun mics. There's an HDMI port with clean, uncompressed output, a micro-USB port for data transfers and charging the camera's 1,080mAh battery pack (the same cell included with NEX cams and select recent Alphas), a dual Memory Stick/SDXC card slot and a tripod socket on the bottom. The camera is very comfortable to hold, and while it's heavier than you'd expect, it won't weigh you down as it dangles from the neck strap.
Sony hasn't changed its UI much since the NEX series' inception in 2010, but like the other RX models and recent Alphas, the RX10 features a tab-based interface that we much prefer. Settings are easy to locate and with everything presented in a linear format, it's easy to jump from category to category to make all the adjustments you require without first returning to a home screen. Shooting options like file size, ISO and SteadyShot are presented in the first tab; custom key adjustments and display options are in the next tab, followed by wireless-connectivity features, then playback; and finally general settings like volume levels and monitor brightness are in the fifth tab.
There are also plenty of dedicated controls on the camera, so you won't actually need to spend much time in the main menu at all. A function button to the right of the LCD launches a quick-adjust mode, with direct access to drive mode, flash options, ISO, white balance, metering, et cetera. A display button cycles through different display modes, including a full-screen live feed, an advanced settings panel with histogram and physical alignment indicators and an image preview screen with a comprehensive settings readout positioned at the border. There's also a dedicated video capture button, a secondary settings dial and a control ring on the rear. Up top, there's a backlight button for illuminating the monochrome LCD, a flash release button, a user-configurable button, an exposure-compensation dial and a zoom toggle around the shutter release. There's also a focus-mode selector on the front of the camera, just below the lens.
With built-in WiFi, you can also control the camera using a smartphone or tablet running Sony's PlayMemories Mobile app. After connecting to the camera's wireless hotspot, you can only shoot in auto mode through the app -- as soon as you connect, auto will override any of the current camera settings. Images are transferred to the connected device immediately after capture. While this is a decent solution for group self-portraits or other tripod shots, due to the lack of control options, we'd recommend shooting directly on the camera then transferring images to the app either from the camera's playback mode or the live gallery viewer in the app. Wireless connectivity makes sharing images online a breeze, however -- your Instagram account will benefit tremendously from the RX10's large sensor and powerful lens.
Performance and battery life
At launch, Sony's RX100 came along with an ambitious price tag -- $650 was a tremendous sum for a point-and-shoot, particularly one that didn't look much unlike a model half its price to the untrained eye. But phenomenal performance -- for any camera, really; not just a pocketable compact -- made this the must-have everyday cam of 2012. You could make the same argument here. The RX10 brings that level of performance to a significantly larger, albeit more versatile form factor. Shutter lag is more or less nonexistent and the camera's speed overall is virtually flawless. Even wireless transfers are more seamless than we've experienced with most other cameras, including past models from Sony.
The camera can power on and capture its first shot in a hair over 1.5 seconds. When moving the frame between a dark wall six feet in the distance and a computer-based stopwatch inches from the lens, the RX10 was able to expose and refocus in about 0.25 second. Meanwhile, in the speed-priority continuous mode, we were able to shoot 20 consecutive JPEGs at nine frames per second, compared to the "approximately 10 fps" that Sony quotes in its specifications. As for transferring images wirelessly, it took 17 seconds from selecting an image on the camera to receiving a 2-megapixel image on the phone, including the time required for the phone to connect to the RX10's WiFi. Transfers were much speedier when selecting images on the phone instead, as the two were already paired. A 2-megapixel image took about one second to transfer, while a full-resolution shot took just five seconds.
Battery life, as you'd expect from a camera this large, is excellent. The RX10 uses the same cell as every past NEX camera and the recent Alpha mirrorless cams, so you may already have spare NP-FW50 1,080mAh packs sitting around. Cheap knockoffs are available for less than 20 bucks, or you can pick up an OEM Sony model for roughly twice that price -- if you're planning to be away from an outlet for a few days, it wouldn't hurt to grab a spare. Still, we managed to make it through each full day of shooting with plenty of juice to spare. For the sake of completing this review, we spent two days shooting without recharging the battery. The power meter reflected a 31 percent charge remaining after capturing more than 700 images and five minutes of 720p video, along with several WiFi transfers and a few on-camera image reviews.
As if you didn't already have enough to look forward to with the RX10... Image quality, no surprise, is spectacular. Really, with a $1,300 price tag, we wouldn't settle for anything less. Regardless of whether you're shooting in bright daylight or a night street scene lit by a single dim lamp, shots are sharp and free of noise, even at ISO 6400. Video looks fantastic as well, even when captured at night. Let's take a look at some samples.
The RX10's fast power-on and focus times make it easy to get the shot. In this case, I heard the helicopter approaching just moments before, and after a quick adjustment on the mode dial, I was able to snap this frame without delay. The exposure and color balance are accurate, and details are relatively sharp (keep in mind that both the chopper and the bird were flying along very quickly).
The tilt-up display and 24-200mm lens give you a lot of flexibility. For this shot, I was able to shoot from the waist and at a distance, allowing me to avoid alerting my subjects. For street photographers, this is a must. Details are very sharp, and while the colors appear muted here, they do accurately reflect the diffused light caused by cloudy conditions in Zurich.
This shot, from a Tel Aviv park, is accurately exposed. Again, colors don't appear to be terribly vibrant, but they do accurately reflect what I saw at the scene. With the camera selecting a sensitivity of ISO 1250, the noise-reduction processing kicked in, resulting in slightly soft details around the dog's eyes and nose.
ISO 3200 enabled a sharp capture in this relatively dim alcove in Jerusalem's Old City. Colors are accurate (if you forgive the abundant fluorescent light), and details (such as the text on a cloth bag) are quite clear and noise-free, despite the high sensitivity.
The RX10's aperture ring, mounted around the lens, lets you access specific f-stops directly. I selected f/16 for this star sun effect, but the small aperture also resulted in slightly blurry details, as you can see with the electricity poles in the inset image. The frame looks great otherwise though, with excellent exposure and color balance.
The RX10 handled these snowy Zermatt conditions with ease, snapping hundreds of photos on the slopes with excellent exposure. This frame is no exception, and with the aperture set at f/8, details in both the foreground and background are quite sharp. The camera also held up very well in the cold weather conditions -- it didn't skip a beat, even in heavy snow.
Look at that detail! The RX10 is a master of focus and exposure, as evidenced by this shot through a Swiss jewelry store window. Elements throughout the foreground are incredibly sharp, despite the relatively high ISO, while the watches in the background are properly blurred, as you'd expect with an f/2.8 aperture.
Video quality is equally impressive. We shot the majority of our sample clips at 1,440 x 1,080 with MP4 encoding for easy uploads, but the RX10 is able to capture at resolutions of up to 1080/60p with AVCHD encoding. Exposures were spot-on across the board, and even video captured at high sensitivities (ISO 12,800) looked better than expected. We stuck to ISO 3200 for the sample reel, however, which you can see embedded above.
