The Nikon d90 arrives fashionably, just as its predecessor did in late 2006. The d90 comes sauntering in with most of the current hot features, plus a new twist that will bowl them all over with its relevance and utility. With a 12.3-megapixel sensor, the d90 rises to the resolution of the more professional Sony Alpha DSLR-A550. It also shares the same sensitivity as the Sony Alpha DSLR-A550, ranging from ISO 200 to 3,200, plus L1 (100) and H1 (6,400). Another essential upgrade on the d90 is the move to a high resolution 3-inch LCD screen.

You may choose Sony Alpha DSLR-A550 with its new 14.2 megapixel Sony Exmor CMOS sensor in the APS-C size format to make detailed and extensively large photos. It actually produces a 1.5X crop factor (35mm film equivalent). Sony Alpha DSLR-A550′s  large, APS-C format means high sensitivity, powerful depth-of-focus control. This Sony Alpha DSLR-A550 DSLR camera’s Quick Auto Focus Live View helps you solve your problems regarding slow focusing or the blacking out on the LCD before focus. You can also achieve finer and detailed photos through the Manual Focus Check Live View.  The temporary 7x and 14x zoom views allow you to focus on very fine detail. On the other hand, the 1x view shows 100 percent framing in the LCD. Sony Alpha DSLR-A550 also features the face detection technology for you to get the appropriate focus, exposure, and white balance. This technology automatically finds the focus on the subject’s face in order to get the center. Sony Alpha DSLR-A550 also ensures that you can capture pictures with all smiles because it has a smile shutter technology that automatically fires the shutter as your subject smiles. Sony Alpha DSLR-A550 has an articulating 3.0 inch LCD monitor with 921k dot composition that helps you capture photos at any angle whether high or low-angle shots. The LCD can be tilted by 90 degrees up or down and features Sony’s Clear Photo LCD display technology. This Sony Alpha DSLR-A550 camera can also be used for capturing in a sports event because it can continuously shoot for up to 7 frames per second in speed priority mode.

The d90 920,000-pixel display has a 170-degree viewing angle and appears to be as nice as the new screens. It makes checking focus and using Live view mode that much more pleasant. New to the intermediate range for Nikon, the Live View feature offers some new tricks over the mode found on the d90 high-end predecessors, particularly including Face Detection. Surprisingly, there is no phase-detect autofocus available on the d90 when in Live view mode, only three contrast-detect modes: Face Priority, Wide Area, and Normal Area. Just as we’ve seen on consumer cameras, in Face Detection mode, a box surrounds detected faces and follows them around the screen. The d90 can track up to five faces. Live view is activated with a dedicated button just right of the LCD. Click here to more of d90 best features.

Here is a summary of d90 review from a satisfied customer:

Designed for serious shooting, but fun to use! Lots of customizations.

ERGONOMICS – The D90 is solid, tight, and well-balanced with the 18-105 VR lens. It’s always ready and it shoots very fast. I love all the direct access buttons; they’re easy to press, with good tactile feedback. And since you’re not going into the menus as much, you can work faster. It’s heavier than the D60, but that’s OK. It’s still very manageable to carry around and it fits my average-sized hand better too. The shutter sounds different than the D60 (if that matters to you). It sounds more like a professional camera; more like a fast “whoosh” than a “click-click”. And there are so many internal customizations that you can set it up exactly as you want.

Though Face Detection is helpful in Live view mode, its utility goes further, as it’s now an integral part of Nikon’s Scene Recognition System (SRS). Thanks to the Nikon d90 420-pixel matrix metering sensor, the SRS can combine color metering with autofocus sensor data and tune white balance and exposure with a particular bias toward getting faces exposed properly. In theory, this should also include making sure the Nikon d90 focuses on an eye rather than a nose or forehead. If true in practice, this is quite an advance. Face detection even comes into play in i-TTL Flash control.
