The Sigma DP1. Unique. Groundbreaking. A compact digital camera with all the power of a digital SLR. For the ďŹ rst time. Ever.
Finally. A compact digital camera with principles.
No compromises: thatâ€™s the key. It means doing it your way, all the way. Being true to your unique talent. True to your own vision. True to yourself. The DP1 makes no compromises. This is a camera for the photographer with a unique, highly individual agenda. This is how cameras ought to be. Itâ€™s just that nobody managed to make them this way. Until now.
This photograph shows the approximate dimensions of the Sigma DP1.
Sigma has developed an integral-lens compact camera with the spec of a digital SLR. In other words, the DP1 has all the functions of a full-spec digital SLR, packed into a compact camera with a built-in lens. This is indescribably hard to do. That’s why nobody has ever done it before. Here at Sigma, we focused all our resources on achieving the nearly-impossible. That’s because for Sigma the standards for good photos and good cameras are constant. Sigma is not about creating run-of-the-mill photographs, or pursuing image quality deﬁned by numbers. Our basic principle is to capture the truth. We’re on a quest for the essence of photographic reproduction, which is to record things exactly as they are. And now this uncompromising conviction has opened up a whole new horizon in all-in-one digital cameras. The sensor is key here. If the camera is an eye, the sensor is its retina. The DP1's sensor is just as big as the one in a digital SLR. So, in its unparalleled capacity to capture light(*1), the DP1 leaves conventional compact cameras far, far behind. And that's not all. The DP1's sensor(*2) is also unique and ground-breaking because it captures all the light, using three layers of color-sensing pixels. None of the light data gets lost or distorted. This sensor guarantees pure, unadulterated image quality, because it reproduces colors and textures as they really are. Then there's the brand-new "TRUE®"(*3) imageprocessing engine. Even when you're shooting at full resolution in RAW mode, the data is recorded so swiftly that the DP1 won’t ever feel slow. It’s just like using a DSLR. And let's not forget the lens. Using our many years of expertise with optical lenses, we've developed a lens(*4) specially for the DP1. Powerful enough to capture the tiniest nuance, it exploits the full power of that sensor. We give you the world's ﬁrst full-spec compact digital camera. A compact with the potential to capture exactly what you see and what you feel, with no compromises. Now you can capture images you might not even have seen before. DP1 The all-in-one camera that will open your eyes.
Full-scale, SLR-sized image sensor 1: The DP1's sensor boasts about ten times the area* of a conventional compactcamera sensor. The biggest advantage of a large sensor is that the sensor pixels themselves, embedded in silicon, are also large. A conventional compact digital camera is made up of miniaturized sensor pixels on a small silicon motherboard: the more advanced the model, the smaller the pixels, and the higher the pixel count. Pixel miniaturization, however, can only go so far. The smaller the pixel, the poorer the quality of the light data captured. That's why we took a different approach, increasing the size of the sensor itself, so that rich image data can be captured faithfully, and so that the color signal is superb right from the start. * The DP1's integral sensor is about 12 times the size of the 1- to 2.5-inch sensor, and about 7 times the size of a 1- to 1.8-inch sensor, used in a conventional compact camera.
Foveon X3® Direct Image Sensor 2: The image sensor in a conventional digital camera has a fundamental ﬂaw: each sensor pixel only captures a third of the light, so complex computations have to be performed in order to complete the picture. A color ﬁlter is used, and the gaps in the light data are ﬁlled in by interpolation. So, no matter how many extra pixels it has, a conventional sensor can only offer socalled "high image quality" by artiﬁcially generating colors that were never captured in the ﬁrst place. The DP1, however, uses the Foveon X3® direct image sensor, which relies on a full-color capture system taking in the full complement of color data. This radically-innovative process delivers genuinely uncompromising image quality.
Brand-new "TRUE®" image-processing engine 3: Thanks to its unrivaled expertise, Sigma has succeeded in developing the world's only digital SLR camera with an integral direct-image sensor. Conventional digital cameras use image-processing based on the Bayer sensor, but Sigma has developed a proprietary image-processing algorithm of its own, which uses the highgrade optical signal captured by the largesize direct-image sensor, and generates a high-quality image. In short, Sigma has created a new digital signal processing engine. We call it the TRUE : Three-layer Responsive Ultimate Engine, or "TRUE" for short. Without making any compromises in image quality, the TRUE® engine performs sophisticated image-processing computations so swiftly that processing times are slashed by an amazing 75%, according to Sigma's own reckoning. Thanks to the TRUE® image-processing engine, the DP1 never feels slow, even when you’re shooting in RAW data mode.
Integral lens does justice to the large sensor 4: A photo is only as good as the lens it was taken with. This is Sigma’s ﬁrm belief, and having spent years developing optical lenses, we should know. The DP1 is the culmination of years of lens-related R&D. And because the DP1 has a large, full-color sensor, we had to develop a special lens to do justice to this extra power. This is the integral 16.6mm F4 lens (28mm equivalent), designed to give the photographer full scope for artistic expression.
