The Sigma DP1s is a compact digital camera is different from the mainstream in this genre. It is described by the manufacturer as a compact "with the soul of a DSLR". So it should be a compact camera make their functioning and image quality comparable to those of an SLR. To achieve this has built a large, fancy CMOS sensor and built an excellent optics with fixed focal length Sigma. In addition, the settings can be adjusted manually, including Focus, the camera also provides images in the RAW-format. Today's compact cameras have an increasingly higher number of pixels as most clients afterwards directed mainly in their purchasing decision. However, the sensor has a small area in these cameras, because large sensors and associated optics are more expensive to manufacture. For physical reasons, a smaller sensor but higher noise to know (low image quality) and the built-in optics usually have numerous aberrations on. The sensor in the Sigma DP1s but has an area such as the sensors in a normal APS-C DSLR. The built in her lens has a good resolution, low vignetting and distortion is annäherend despite its 16.6mm focal length. According to the Sigma DP1s can keep up with a DSLR. Well, can not keep up the DP1s in the following aspects: 1. It has no viewfinder which is problematic in low light conditions. While there is an attachable viewfinder as an accessory but it is very expensive. Even so, the Schärefentiefe unverifiable. 2. Also in terms of speed can not keep up with a DSLR the DP1s. For me, this is not a disadvantage, but it should be noted that the camera to extend the lens, for reading the images from the chip as well as their storage needs on the sdcard long. However, the camera is not intended that they are considered to be mindlessly subject, and then pulls the trigger just once. There should be a full-fledged replacement for a possible reflex, if the photographer is time traveling by bicycle and etc. will cause no bulky equipment with them. Definitely a par is the compact Sigma with a DSLR when it comes to image quality. I can confirm here that Sigma DP1s delivers very good images. Little noise, little vignetting, high sharpness up to the edge and a high dynamic range make the DP1s an excellent camera. They trumped most DSLRs, where hangs a standard lens (such as the Pentax K10D with 18-250mm zoom). Also noteworthy is that the sensitivity can be set to ISO50. I also want to emphasize that a prime lens is the zoom verzuziehen because the photographer then has to deal more with the image composition and will continue to evolve so here. In terms of image quality can therefore easily keep up with a DSLR compact DP1s. Since these were the requirements for my purchase decision, I am very satisfied with the Sigma DP1s. The workmanship and the materials used are top and have a 08/15 compact camera look like a toy. Swabs (the missing fifth star) I'm determined to little things: The Objektivdekel is simply clamped onto the lens and I am wondering if the flap does not wear on the cover over time. Since it is a compact camera on which the lens can not be replaced, it would be practical if the cover would be attached to the camera body via a Schnürrchen. In addition, the white balance is unreliable and often have to be corrected at the PC. In summary, a very good camera, placed in a Marktniesche and definitely an alternative to overpriced Leica X1. At least apart from the aspect of the aperture of the lens. Unless of course, you want a camera to specify. Then you come anyway not past a thick DSLR or M8.
