It's one thing to be fashionably late to the party, but it's another altogether to be just plain late. The RX100 is Sony's first large-sensor compact camera, and while it definitely falls in the latter camp, it comes bearing many gifts that make up for the wait.
Design and features
Quite aptly given its raison d'être, the RX100 is small, fitting comfortably in your hand or pocket. It feels particularly well made and sturdy, thanks to its aluminium frame, though its exterior is rather slippery. This means that you will most definitely need to attach the included wrist strap to ensure that it doesn't fall out of your grip.
Buttons are on the small side, which adds a nice, refined feel to the shooting experience, but some users might find them a little too small for comfort. A mode dial at the top of the camera keeps things simple and uncluttered, housing controls for full PASM control, as well as automatic, superior automatic for low-light shots, movie and panorama modes.
The 3-inch LCD screen is quite something to behold. While it's only VGA resolution, it has a third set of white pixels that helps boost the brightness when used in sunny situations. It's able to display a lot of detail, and does hold up when used outdoors — not perfectly, but it's better than a lot of other compacts.
Most people will be interested in this camera, as it boasts one of the largest sensors in a compact model, beaten only by the Canon G1X (which is big enough to almost not be classified as a compact) and the Fuji X100. It's 1 inch, which is the same size as the one used in the Nikon 1 series of cameras, and just a bit smaller than the Micro Four Thirds sensor.

A Carl Zeiss lens that extends to 3.6x optical zoom sits at the front of the camera, and it's nice and bright, with a maximum aperture range of f/1.8-4.9. The widest aperture, f/1.8, is only available at the extreme 28mm end, and stops down to f/2.8 when zoomed in to 1.2x optical zoom.
The control ring around the front of the lens is an excellent way to offer a refined shooting feel, allowing you to adjust parameters such as aperture, ISO, white balance, the dynamic range optimiser and creative filters.
An incredibly stylish camera to look at, this is the RX100 front on.
The RX100 has truly been designed with a serious photographer in mind. If you are a fan of using manual focus, the RX100's implementation is seamless. The control ring around the lens moves freely, with the camera automatically entering in to expanded focus. One of the other excellent surprises that awaits you within the menu system is peaking, which assists with focusing and is a feature traditionally found on video cameras. You can select the colour, as well as the intensity. The pop-up flash can be tilted back to act as a bounce off the ceiling, too, though it is positioned in such a way that it can obstruct how you hold the camera.
Some photographers will be perturbed at the lack of a hotshoe for mounting an external flash, or some sort of accessory port for an electronic viewfinder (EVF). They're not serious omissions, but they would have helped it stand up just a little taller against competing cameras, such as the Olympus XZ-1.
The RX100 charges its battery in the camera, with an included USB and adapter in the box.

Sony rates the battery at 330 shots. The above continuous shooting speed measurement was taken in speed-priority mode, though the RX100 also has a regular continuous mode, which captures at 2.5 frames per second, allowing for continuous AF and exposure. In speed-priority mode, the RX100 slows to process images after taking 12 frames, and has fixed focus from the first frame.
The RX100 produces excellent images in a range of shooting situations. Whether it's in one of the automatic modes or full manual, more often than not you'll end up with a keeper shot rather than a dud.
Colour rendition is excellent, with good levels of saturation to the JPEG images delivered by the camera. Lens sharpness is also very good, though there's a slight amount of softening as you reach the sides of the frame. It's still a pretty impressive performance for a camera of this class.
At the time of writing, no third-party programs such as Lightroom or Adobe Camera Raw are able to read the RAW files from the RX100, so we've had to perform our conversions using the Sony software. It's not provided with the camera, so you have to download it separately (download it for Windows or Mac).
The options presented for conversion in the Sony software is, shall we say, somewhat limited. Even so, the RAW files from the RX100 deliver a very good amount of detail, but we can't help thinking that we could have got even more from these files with a third-party converter.
This is a comparison of the RX100's rendering of RAW and JPEG images. The same shot was taken at ISO 800, with 100 per cent crops inset. As you can see from the crops, the camera's RAW files have quite a bit more usable detail, though colour rendition is very similar. Noise is also kept well under control in the camera's JPEG processing.
High ISO performance is impressive, but not quite at the level as another camera of this type, the Canon G1 X. At ISO 3200 and above, there is quite a bit of noise present on images. Where the RX100 excels is in its superior auto mode — also found on other Sony cameras. It's an (almost) foolproof way to take clear shots in low lighting, made even better than before, thanks to the relatively large sensor and lens that can gather more light at f/1.8 than other models.
The RX100 can almost see in the dark. This shot was taken late at night, with just the illumination from a sole street light. At 1/6, f/2 and ISO 3200 using superior auto mode, it can still take a very usable shot, particularly when resized for web. See the full-sized version below.
When shooting at f/1.8, the RX100 is able to deliver some incredibly pleasing bokeh. It's not going to be the same as that produced by an SLR, but it's smooth and mostly rounded nonetheless.
Like to shoot at f/1.8? So do we.
One issue when shooting a lot in high-contrast situations is the screen, which has a tendency to make bright areas look overexposed even when they're not. This is easily compensated for by using the histogram and checking the exposure. The lens also shows plenty of barrel distortion at 28mm, though since it's fairly even, it will not be too much of a problem to correct in post-processing.
Video quality from the RX100 is very good for a compact of this class. The audio quality in particular delivered from the stereo microphone is excellent, picking up on lots of detail and providing great separation. The zoom is not particularly smooth when filming, though the continuous autofocus works very well in adjusting to moving objects in the frame.

Offering snappy performance, excellent image quality and a sleek design, the RX100 proves that good things come in small packages. Sony's first large-sensor compact took its time to arrive on the scene, but it's just the camera that the advanced compact category needs. An advanced camera with more than enough controls to satisfy seasoned photographers, and plenty of automatic modes to welcome beginners, the RX100 is bound to find a place in many people's hearts.
