The two seem completely at odds with each other?? Image quality and size. This is a basic rule, have been since the invention of photography, that a larger camera with the inclusion of a larger area (it’s silver, or silicon) a ?? â ceteris paribus?? produce excellent image quality. And so photographers schlep around cameras and lenses, they charge, all in one searching for the optimal image.

On the other hand, we would all like without stress. To walk in a foreign city (or dangerous), would be without the weight and sometimes draw attention to a digital SLR Nice. To walk in the forest with the couple to photograph the mist of early morning or a chance encounter with a deer, no baggage (both literally and metaphorically) that includes a camera is a bit like many of us.

The digital revolution has given us no end of cute, small, inexpensive and well featured camera bag seems, would do. For some users do. For photos of family events or photos, at the end that the smaller prints from Wal-Mart, they are often very good. But for the most serious photographers and more demanding, regardless of the appeal of these cameras could be in terms of functionality, they are generally disappointing in terms of image quality (Kodak).

The reason is simple: sensors of small size. For example, the Ricoh GR 2, a popular Pocket Digicam more serious photographers, has a sensor that measures 7. 6 x 9 5mm. Take a ruler to see how small it is a?? About the size of the smallest fingernail. And as we know, the small sensors, particularly those with a high number of pixels (which we all want, in particular) have very small photo-sites. Net A results?? noisy images, even with low ISO settings, or if the manufacturer has used aggressive noise reduction on chip at lower resolutions.

A sensor APS-C

This brings us to the Sigma DP-1, the subject of this report. For the first time we have a T-shirt-pocket digital camera with an APS-C approximately. That’s about the size of the NPC as the popular Canon 40D and Nikon D300 used, and a little larger than size 3.4 by Olympus and others used in their DSLRs.

The comparison is a bit easier to observe if we compare the diagonals of these formats. The Ricoh GR 2 and Canon G9 (and similar devices) have sensors about a diagonal of 10 mm. On the other hand, a 3,4-format digital SLRs like the Olympus has a 5mm diagonal 22nd. A standard Nikon or Canon or Pentax digital SLR with an APS-C has about a diagonal of about 28mm. Godzilla was really a?? Size is important.
