I got an used D3200 and I've been using it a prime 50mm 1.8D with no issue whatsoever. Yesterday I got my 18-55mm f/3.5-5.6G which I also bought 2nd handed on ebay and I simply cant focus anything. I've changed various settings regarding AF but nothing works. Is something wrong with my camera / lens or I am just missing the obvious?
It appears you have purchased the AF-P model of that lens. These lenses use a stepper motor, and for whatever reason are only compatible with the D3300 and newer — not your D3200. (Presumably, the new motors need a more complex interaction that the older models just aren't prepared for.) You'll need to look for an AF-S model — there are four of them:
- AF-S DX Nikkor 18-55mm f/3.5-5.6G ED (2005)
- AF-S DX Nikkor 18-55mm f/3.5-5.6G ED II (2006)
- AF-S DX Nikkor 18-55mm f/3.5-5.6G VR (2007)
- AF-S DX Nikkor 18-55mm f/3.5-5.6G VR II (2014)
The latter two add VR, and you can read more about the differences at What is the difference between these two 18-55mm kit lens options for the Nikon D3100?
But, unless someone is basically giving one away, I'm not sure I'd recommend it. Personally, I'd first look at the AF-S DX Nikkor 35mm f/1.8G to complement your 50mm prime, but if you're really feeling you need a wide-normal zoom, I'd instead look at saving up a bit more for something like the Sigma 17-50mm F2.8 EX DC — this will cover about the same range, but let in more light and give moderately better technical image quality.
