Nikon D90 SLR

Nikon D90 is a great prosumer DSLR in this price range. As someone else pointed out - anything lower than a D90 is not worth being called a DSLR.

Customizability: You can shoot in multiple resolutions, multiple sizes and in JPEG/NEF formats. It has the standard nikon variety of white balances and picture tones, but setting anything is extremely simple once you get a hold of your camera.

Ergonomics: It fits your hand nicely, unlike the D5100 and D3100. Really rock solid, and you immediately get the feel that you're ready for the shoot. The two dials (one for aperture and another for shutter) is much MUCH better than having just one dial as D5100, or any Canon in this range.

Low light performance: Pretty decent. I usually go up to ISO 1600 when I'm in low light, and the pics that come out are usually good enough, with very less graininess.

Battery: Extremely reliable and long lasting. Doesn't take a long time to recharge, and takes about 1000 shots (if you don't use flash).

Autofocus: YES! Which is another big differentiator in the low end cameras like D5100 and D90. The camera itself has an autofocus motor, and it's compatible with all lenses. On a D90. you don't need to buy expensive lenses with AF motor, just because your camera body sucks.

Included Software: Horrible :) Just use Adobe lightroom or Aperture, and you'll be good.

Included Kit lens: 18-105 is a very versatile lens and extremely reliable too. It covers most of the range that you're likely to encounter. Also, the autofocus on this is very silent.

Video: Pretty basic. No autofocus makes it useless for me, really. Even the most basic camcorder is better than a D90 when it comes to video.

Overall - 4/5, mostly because of useless video functionality and due to the fact that D7000 tops D90 in all departments.

The reason is simple.....it has a more professional body....and gives a feel of actual higher end pro bodies.....lots of switches on the body for tweaking all imp settings u need to change to get that perfect shot....once accustomed.....u hardly have to delve into menus.....just like riding a bike....controlling everything without looking at your gear.....

Whereas in lower end (till d5100) models....u would actually delve into that "nice" menu to change aperture, iso, WB etc......instead of capturing those split second moments u bought your dslr for !!

Nikon D90 a great camera, with all the features that needed for excellent photography.
If we can understand the manual and try all the modes... you become an expert of photography...
real good camera...
I'd say this is the best when compared with D5100 and D7000 with in the budget

I watched many people using entry level DSLRs, but the fact is, the photo
quality of those DSLRs are never the same, which is the main criteria for
buying a DSLR. Pictures look blotchy and not sharp, specially at night
photography on those cameras.
I bought D90 even though some newer models were available at that point of
time. The reason behind that was its great handling. If you want to take
photography seriously and upgrade your camera later on, D90 provides you
the same features that other pro cameras offer, including buttons and
others features which are essentially same. 12 megapixels are good enough
for me, and in daylight the camera is a marvel (I compared my prints with
my friends who owns a 5DMII and daylight pics are at par). But the camera
pic suffers at night, due to low ISO tolerance. Obviously adding a big
aperture lens improves the quality drastically (I use one f-1.4 50 mm
prime for night), and adding an external flash can really help you out.
Focus speed is not the fastest, but does not matter as long as you do not
shoot sports. Weight and ergonomics of the camera is just awesome (an
essential for a DSLR, as users know it, a bad ergonomically designed
camera weighing more than 1 kg can really hurt your hands for sure). ISO
range till 1000 is ok, after that noise is very obvious. Camera features
some basic post-processing features, but nobody uses it. 12 bit compressed
RAW is a impressive feature and every serious photographers should learn
how to use RAW photographs. In built flash is just not good, you need to
buy an external flash. VR lenses work fine with this camera (some camera
in Nikon lineup has this problem). Best photos can be taken (according to
me) in landscape photography and in abstract photography.

Excellent camera, Beast thing is it has a AF Motor, you can buy D type lenses and save lot of money, It is the best semi professional camera and the price is also good.
In flipkart its slightly higher price. I was available for 55,000 in the month of April.
I will recommend this camera to anyone. Do not waste money on any other camera which does not have a AF motor, you might think you saved money but you will end up paying double the amount for lenses with motor.
If you are not sure were to buy then go ahead and buy from Flipkart.
