I have Nikon D3200 and I use it for landscape photography and I can get great shot comparable with today 10, 000 Dollar expensive cameras.
if you want just more megapixel and don’t shoot action / birds D3200 is best you can get. if you wanna action too than maybe D5300 also can almost give what you want.
I still love to shooting with my D40 and my D50 and my D200 in my free times. and I use my D810 only when I want to print my pic’s. this is one of shots with my Nikon D50.
