Best Image Digital Camera with Resolution Atleast 18 Megapixel

The bottom line:
Canon's EOS 1D Mark III offers a luxurious cocktail of high-resolution, extremely low noise, blazingly fast burst shooting, abundant customization, and a build quality and ergonomic design among the best you'll find in today's camera market.

The 1Ds Mark III marks another high-end success for Canon, though you'll need a lot of spare cash if you want to own this ground-breaking camera.

At ISO 100, the Mark III was able to hold detail over an 11 EV dynamic range, and more than nine EVs at ISO 1600 -- quite impressive. *

The Canon EOS-1Ds Mark III offers you every possibility to capture the ultimate picture. *

All a900 accessories are compatible with the a850 camera,
in November for about $800. EV bracketing with a 2EV range makes
it easy to create high dynamic range composite images. *

Built-in image sensor-shift stabilization. Noise at ISO 1250 and higher. *

The bold black/white elements are good for seeing the colored fringes caused by CA in the corners of the frame. *

Some settings like ISO and EV are easily readable via the top Status LCD, but items like Drive and WB can be cryptic, so it's better to use the rear Status display. Most astonishing was to take a 24mm wide-angle photo of the World of Coke in Atlanta from across a large field and be able to almost recognize faces standing near the building. *

Colors were extremely rich and saturated, but not too much (we shot in the standard mode). *

Colors are vibrant despite the overcast skies. The details of the leaves in the foreground are very sharp in the image below, and there is no trace of purple fringing at the area where leaf meets bright sky. *

The Canon 7D's hue accuracy is quite good, just a hair less accurate than the 50D. Most of the other colors are very close to technically accurate saturation levels. Flesh tones shot with the Canon 7D appeared quite natural, with appropriate saturation levels and accurate color. The Manual and 2,600 Kelvin white balance options were very similar, both producing fairly neutral images. Color and saturation are very good, though a tendency towards slightly high contrast under harsh lighting. The Canon 7D's default contrast is a little high, producing some washed-out highlights and dark shadows under the deliberately harsh lighting of our "Sunlit" portrait test shown above, though the camera's contrast and highlight tone priority settings do help tame the highlights quite a bit. ISO 1,600 is very usable for average print sizes. The Canon 7D's images are very clean at ISOs 100 and 200. The grain is slightly more evident at ISO 800, but detail remains very strong. Color balance was pretty neutral with Canon 7D's Auto white balance setting, even at high ISOs and lower light levels. ISO 1,600 ones looked pretty good, albeit with some visible noise in areas of flat midtone tint. ISO 12,800 shots were acceptable to good at 4 x 6. Detail at high ISOs was very good, with the Canon 7D doing an excellent job of holding onto detail while also reducing noise. *

It's interesting that Canon has essentially had no camera in this category until now. The Canon 7D's autofocus system has quite a few new features worth mentioning, and some of them are related to the Metering system, which we'll get to in a moment. *

You'll be very happy with prints from the camera at up to 24x36 inches. The color balance is very cold on this image, but that was accurate for the light, so it's hard to fault the camera. The Canon 5D Mark II's image quality is remarkable. It's important to note that this is still a tool for photographers, though, and doesn't yet replace the ease of the most basic camcorder, because it lacks autofocus; and significant exposure changes can result in momentary gaps in the video. *

The long-awaited successor to the 5D has arrived in the guise of the 5D Mark II. With its competent HD video functionality and excellent image quality, this camera doesn't disappoint.

Lens-based Image Stabilisation was enabled for all handheld shots and disabled for tripod-based tests. *

The quality was really poor, and it picked up the internal mechanical sounds of the camera. It's pretty evident we liked this camera. *

Canon's EOS 1Ds Mark II offers a wealth of features and the highest resolution of any small-format digital SLR, with a price to match.

This is undoubtedly Nikon's best digital camera yet, though for most of the functionality you can easily get away with the D700 for a lot less, and still have around 95 per cent of the tools and features. But as usual, it's that extra je ne sais quoi that makes this camera so special.
