The 3.5-5.6 kit lens has a great minimal focal distance, but it's on the slower side. You'll also find it soft wide open and want to stop it down to get it sharp. Upping the ISO past 1600 on the D5200 will generate a lot of color noise so if you use auto ISO set it to 1600. White balance won't be an issue if you shoot in A,S, or M mode and export RAW. If you plan on using auto mode and exporting jpgs you're really not going to see a big difference in pictures. If you're going to spend the money on a DSLR, learn how to use it because a D5200 is a VERY capable camera, especially if you get some nice glass.
