DC SLR from fear! .Appreciation of samples to get started early DP1.

<P> Primer: <EM> there a camera can also have "excellent image quality and compact portable body?" From Japan SIGMA (Sigma) Company said: Yes, that is, we produce the DP- .1. .Now the bounce up to 1 year old little guy finally came before us. .</ EM> </ P> <P> If, after people complained about the small DC is the largest the size of the sensor is too small: whether it is Sony's 1/1.7 inch CCD class or Fuji 2 / 3 inch Super .CCD, the present volume consumer camera to use the maximum size of the sensor, compared to SLR camera at least 4 / 3 inch image sensor size is still negligible. .</ P> <P align=center> <center> </ center> </ P> <P> DC, but the consumer and small compared to SLR biggest weakness is difficult to use in some special circumstances: for example, .limited volume of film equipment, the noise is limited to the film equipment, shooting the environment is limited and so on. .In short, the film 135 times, people welcomed the small portable camera, the image sensor size of the digital age limit, no longer qualified for tasks that require high-quality photography! .</ P> <P align=center> Ricoh GRD Series is uniquely positioned at the end of the previous DC products </ P> <P align=center> the W200, F50fd DC such as low consumer prices have 1/1.72 .inch size CCD, the basic image quality, the advertised high-end GRD, G7 and other products not foothold </ P> <P> particularly in the EPSON R-1D series and the Leica M8 has put into production after it was discovered hopes .on the idea of professional digital rangefinder is also difficult to achieve - because they cost too high, and the efficiency of RF camera manual focus and accuracy are becoming increasingly difficult to meet the current needs of professional applications. .</ P> <P align=center> DP-1 final volume is still small, the only problem is the lens size is slightly larger </ P> <P align=center> DP-1 in ad pages display in front of .small box is the size of 1/2.5 inches to let people know Sigma DP-1 frame in the image on the great advantage </ P> <P> Sigma previously rumored Japanese companies are the way to OEM production for the Leica M series .lens to reduce the operating costs of the latter. .However, before these have not yet been confirmed, Sigma they have a big step forward: DP-1 camera is a rather innovative move, it is not in size, a large number of Bini Kang consumer flagship P5100 camera, equipped with a .APS-C frame of the Foveon X3 sensor. .This makes it have to become a professional compact camera requirements for the major potential. .And compared to existing GRD series of digital comparison, DP-1's greatest strength is its APS-C imaging sensor frame is much larger than the former level 1/1.7 inch CCD! .</ P> <P align=center> Sigma DP-1 mounted on the Foveon X3, for the existing technology for the consumer compared with the previous DC, DP-1 does promise made in the final image quality .Breakthrough </ P> <P align=center> </ P> <P> However, in addition the majority of DP-1 and DC are not very different: for example, use the contrast detection type AF system, all using the LCD viewfinder ( .there is no reliable way of the optical viewfinder). .So I also hope that people will pay attention to Sigma DP-1 excellent image quality - they believe that with Foveon X3 Full Scale sensor itself technology, and APS-C frame contrast 1/1.7 inch huge advantage, able to convince those concerned with image quality .people to accept the production of digital cameras Sigma - SD14 SLR camera previously apparently did not get enough of the market, Sigma hopes to fill with the DP-1 between the SLR and the small DC permanent existence of this huge blank! .</ P> <P align=center> attention to white font: contrast detection type AF, DP-1's focusing performance, can be a huge breakthrough in doubt </ P> <P> frame changes, but because of its sensor .very large, in order to maintain the appropriate maximum aperture, the absolute aperture would have to significantly enlarge - volume control for the Sigma lens is a difficult and ultimately zoom lens does not appear in DP-1, hoping to stabilize the position of the DP .-1 is still equipped with a 16.6mm (focal length conversion factor as close to 1.5 ×, DP-1's 35mm equivalent focal length of 28mm, with the same imaginary opponents view GRD). .The maximum aperture is reduced to F4 (after Russia had its mouth KMZ factory L39 Lo camera in the 50's produced 28mm/F6 the lens, the SLR and rangefinder camera 28mm interchangeable lens seems to be so rare .small aperture of the product), and its sole purpose is to ensure that APS-C size CMOS sensor the edge of the image quality - the size of a small DC is nothing short of the monster! .</ P> <P align=center> </ P> <P align=center> </ P> <P align=left> maximum aperture of only F4, fixed focus 28mm equivalent focal length head shot if there are limitations for the Humanities APS .-C frame sensor, meaning and appearance of the SLR camera lens similar size, Sigma must be as much as possible without affecting the resolution and maximum aperture of the lens under the premise of reducing the volume. .</ P> <P align=left>.
