Nikon D90 review
One of the main attractions of this month had to be the Nikon D90, which is also the most expensive camera we've tested so far. Nikon introduced the D90 to replace D80 trust. The D80 is one of the best entry level mid-range cameras from Nikon.
The D90 has so much to prove before it can earn its place. Passing through the key features D90, certainly looks impressive. The D90 uses a CMOS sensor, 12.3 MP sensor rise from the 10.2 MP CCD sensor of the D80. The sensor size remains unchanged. Most entry level cameras are supplied with a 18-55 mm lens that can be very limiting for the type of pictures you can take. We received the camera with a DX-Nikkor 18-105 mm VR zoom lens.
This makes a good all-purpose computer wide angle and telescopic shot. The shape and size of the D90 is slightly bigger than the D60 we saw a few months ago. It's a little heavier than the D60 and D80 itself. The body is plasticy, but it feels very sturdy and the buttons are large as expected in any Nikon D-SLR.
The D90 now comes with a 3 inch screen that is incredibly vibrant and crisp. The other thing that makes the digital camera interesting is the inclusion of Live View that allows you to use the LCD to focus.
This is a feature rarely found on D-SLR. The D90 is without doubt one of the easiest operate the cameras, if you have a basic knowledge of using a decent camera point and shoot. All camera functions such as ISO, white balance, exposure metering and focus modes, can be accessed by clicking the appropriate button and rotating the dial. The shutter speed and aperture size have dedicated brand.
It is very difficult to criticize the D90 in the quality as well. The 12.3 MP CMOS sensor does its job well. Photos are sharp throughout the aperture range complete. The aim is not made for macro photography, so have difficulty with close shots. Yes, great close-ups can be triggered backing , and zooming into the target. Good depth of field can also be easily accomplished. The flash is powerful and good enough for indoor photography from time to time.
Auto mode works well with the autofocus. The approach is instant and no delay. There are a few hiccups autofocus time to time, but nothing that can not be fixed using the other autofocus modes support. As expected of any digital SLR camera, the manual mode gives total control of the camera. You will not be disappointed with the D90, if you like to select a default scenario, either - a dial to be present.
Another new feature is almost never seen in the D-SLR is the video recording. The D90 can capture up to 1280x720 resolution videos at 24 frames per second. What makes it even more special is that you can zoom and focus manually while recording video. Video quality is great and the frame rate fairly stable, but that you need to buy a fast SD / SDHC for it.
We would be lying if we say that we were not impressed with the D90. It's full of surprises. The camera is incredibly easy to use, has the performance, features, and is certainly light years ahead of the D80 in all aspects. Nikon has another winner on its hands and recommend this option if you have a serious interest in photography and also the money.
The Nikon D90 with the lens is priced at a whopping Rs. 89 890. The body itself can be bought for Rs. 69 950. This makes the D90 almost as expensive as the D300. It has more meaning if you spend more and go for the D300 instead.
Nikon lenses are known to be cheaper than some other brands, so you buy only one body and then a good lens can also be a good move. If you do not need the live view or video recording and even small changes Nikon has done, and then the older D80 is a better buy, especially with its price more favorable to the portfolio.

astronomy binoculars.?
hello all, I just found a wicked prog called "Stellarium" and has re-sparked my interest astronomy. i cannot afford a telescope yet, because I am a student with no money, but I own a pair of binoculars - 12x50 praktica great sport angle of 6 degrees. Am I able to detect planets like Saturn and Venus with this? (Its a cloudy night atm so i cannot test) and how it would look Orion nebula? How much I have to spend on a reasonably decent telescope? beginner astronomer! thanks for the answers tom
Saturn and Venus are visible to the naked eye, so are easily visible in 12x50 binoculars. With the binoculars will soon be able to see the phase of Venus (at the moment is approaching) and brightest of Saturn, Titan. You will not be able to see Saturn's rings, requiring about 25x when well placed, and are not well placed at this time. Remember that telescopes Galileo were not much more powerful than binoculars. There was a little increase (about 20x), but less open and the large amount of chromatic aberration more. The Orion Nebula will look great in binoculars, especially in a dark sky. Here are some websites with good information about telescopes Beginners: http://www.scopereviews.com/begin.html http://www.gaherty.ca/tme/TME0702_Buying_a_Telescope.pdf http: / / observers.org / beginner / For jrfbeginner.html more advanced information, read Phil Harrington's Star Ware, 4th edition (Wiley). You get the most value for your money with a Newtonian reflector on a Dobsonian mount, such as: ~ = ~ = category_id http://www.telescope.com/control/category/ dobsonians pcategory / telescopes / ~ VIEW_INDEX = 0 / ~ VIEW_SIZE = 1000000 http://www.skywatchertelescope.net/swtinc/product . php? class1 = 1 & class2 = 106 buy in a store that specializes in telescopes and astronomy, either locally or online, do not buy in department stores, discount stores or eBay as everything they sell is junk.
