Im pretty set on the D5300. I like the idea of a "superzoom" but I am also familiar with the trade offs with this setup as opposed to multiple lenses. My idea is to purchase a FX lens, specifically the 28-300 f3.5-5.6, the point being i thought many of the errors that you would normally get with a super zoom (barrel distortion, vignetting, etc.) MIGHT be reduced if your using an FX lens on the DX body, effectively using just the center of the glass. Is there any merit to this idea? Thanks guys!
