In the United States, high-quality, expensive compact cameras, which offer better image quality and a near-SLR-equipped equipment compared to their fellow-consumers, are gaining increasing market shares. Pioneer was Canon with the G, now there are similar models also from Nikon, Fujifilm, Olympus, Ricoh and Panasonic, all based on a 1 / 1.7-inch sensor instead of the smaller 1 / 2.3- Set the sensor

Sony is now a step further and integrated into the Cyber-shot RX100 a 1-inch sensor as well as a 3.6-fold zoom with 10.4 to 37.1 mm focal length (28 to 100 mm KB equivalent). This corresponds to the sensor area of the Nikon-1 system with 13.2 x 8.8 mm and thus the three-dimensional area of a 1 / 1.7-inch sensor. However, the solid aluminum case measures only 10 x 5,9 x 3,6 cm and weighs 239 g.
Features
The Sony Cybershot RX100 uses 20 million 2.4 μm tiny pixels, leads to a low-level f3.9 aperture. As a rule, diffraction losses are visible from one diaphragm, which makes shade appearing in the telephoto not advisable. For the telephoto leaves the properly processed Zeiss lens only aperture apertures from f4,9.
Autofocus and video
After all, the zoom at focal lengths is f1.8 quite bright and allows at least wide-angle fading without quality loss. The initial price of the RX100 is 650 euros on the level of the Nikon 1 V1 and about 170 euros on the Canon G12.
Handling
While Canon strives towards the SLR with the equipment of the G12, the RX100 remains closer to the compact camera in two details: The G12 has a viewfinder and accessory shoe, the RX100 does not. Therefore, the user must always take advantage of the built-in flash and the monitor. The flash is so weak that it can be used to lighten up on short recording media (guide number 1)
The RX100's 3-inch monitor, on the other hand, deserves praise. In addition to the RGB, the RX100 also has white subpixels, dissolves very high and provides a clear, sharp, coherent and low-noise preview. In bright daylight, the display remains relatively high contrast, but the surface could be slightly better than the other.
The RX100's range of functions, which are common to compact cameras, is expanded by numerous manual adjustment options, as well as useful features such as an electronic water scale. In addition, there are numerous direct accesses - without the Canon G12 level.
For beginners, among other things, the portrait assistant on board, which aligns the photographed person according to the golden cut in the picture. Intermediate users can select aperture and exposure time in the (partial) manual modes. Very comfortable is also the manual focusing with lens ring and usable magnifying glass (8.6x).
The 25-point autofocus operates reliably and quickly with contrast measurement on the sensor: in good light conditions, the RX100 needs 0.25 in the wide range, 0.34 in standard focal length and 0.54 seconds in the telephoto for focus and release. In series mode, the Sony creates 2.2 B / s and up to 100 images per series.
The full-HD video function convinces with a good picture quality and an autofocus, which pulls the sharpness during the filming unerringly and unobtrusively. Thanks to the video button, the recording can be started directly from the photo mode. To select aperture, exposure time, and other parameters, you need to switch to the dedicated video mode.
No easy task to package the many settings in a simple intuitive operating concept. But Sony mastered them well. Not only because the lens ring can be used universally and is extremely comfortable to handle. The FN key, which allows direct access to five self-defined parameters, is a valuable aid.
The menu is extensive, logically structured in the style of the Sony Alpha SLRs and opens optionally with the first page or last used entry. With the somewhat unclear pressure point of the shutter, however, it is somewhat harder to press the button halfway through half the button and not trigger it at the same time.
Since the RX100 is a camera that is positioned between the compact and SLR class, it has passed through both test procedures. In the case of the compact camera, we measure with maximum wide angle and telescope, and with the SLR test with a 50 mm KB equivalent, where obviously the maximum performance of the lens lies.
Image quality
The RX100 achieves very good DL values up to 1164 LP / BH and combines them with a proper dynamic as well as a fairly balanced relationship between texture loss and noise. The resolution is also excellent with up to 1546 LP / BH for a camera of this size.
In the telephoto, the power falls to the edge less strongly than in the wide angle. This is due, on the one hand, to the edge drop which is typically stronger in wide-angle lenses, and on the other hand, signal processing also plays a part here, which frequently raises contrast in the corners more than in the center >
Conclusion
Image errors of the lens such as distortion and chromatic aberration remain within the frame. All in all, the RX100 has a sensationally good result - the 1 / 1.7-inch compacts have no chance, and even Nikon's 1 J1 and 1 V1 remain significantly lower
Sony lands with its first precious compacts of the new RX line a hit. No other similarly small and light camera currently provides comparable image quality. On SLR and system cameras with larger sensors the RX100 does not approach, but can compete well to the medium sensitivities well - Kauftipp picture quality. A limiting factor is the built-in zoom and the small pixel pitch, which leads to diffraction and loss of resolution for smaller apertures.
According to the excellent results in the above test according to system camera standards, ColorFoto has also tested the image quality of the Sony RX100 after compact camera test procedures. As the RX100 has cut off, you will find in our second test report ("Verified: Sony RX100 in the compact camera test procedure")
