Here is what you get if you buy/upgrade to the Nikon D5200:
- You get a 24 MP sensor, where it is only is 12 MP in the Nikon D90. The new sensor has been measured yet at Dxomark, but expect the performance to be a little bit better than the Nikon D3200, so you will get a nice performance upgrade with better high ISO, more dynamic range. This means that you get better image quality
- You get a better metering engine in the Nikon D5200. This means that there is a better chance of you getting a picture with right exposure (not to light or not to dark) as it has more information to decide the exposure
- You get better better high ISO performance where you now can push the ISO to 25600 vs 6400 in the Nikon D90. That is two stops better. So with this you can take pictures in more dark situations without using flash
- You get a better autofocus engine. The Nikon D90 uses the intro autofocus engine from Nikon, where the autofocus is a middle model in the Nikon D5200. This will mean you have a better chance of getting a sharp image.
- You get a lot more in video options. The Nikon D90 was the one that introduced the video to the DSLR market for Nikon, but a lot has happened since and with the D5200 you get possibility to use autofocus in video mode and to shoot in Full HD. If you use the DSLR camera to shoot a lot of video this alone is reason enough to upgrade
- You get a swipe LCD screen which is primary known from the point-and-shoot cameras.
- If you have older non AF-S lenses. You might want to consider the D7000 or wait for an upgrade to this camera. The Nikon D5200 wouldn't autofocus with these lenses
- The viewfinder in the Nikon D90 is closer to real life with a magnification factor of 0.94x vs a magnification factor of 0.78x in the Nikon D5200. Not that important as you quickly will get use to the new viewfinder.
