So I've been shooting with my old D750 for years now but I've mostly stuck to the 24-120mm kit lens and honestly it just isn't cutting it for the more professional portrait look I want to get for my cousins wedding next month. I've spent hours looking at reviews and everyone seems to point toward the 85mm f/1.8G because it's affordable and has that classic focal length but then I saw some people swearing by the 105mm f/2.8 Micro lens for headshots.

My main worry is the 105mm being a bit too honest with skin textures since its a macro lens and maybe the f/2.8 isnt gonna give me that super creamy background blur I'm after compared to an f/1.8 or even an f/1.4 if I can find a deal. I've got about $650 to spend maybe $700 if I stretch it but I'm looking at the used market mostly since I'm trying to save up for some lights too. Is the 85mm really the best all-rounder or am I gonna regret not going for something longer or faster for those outdoor shots where I have more room to back up? Its just hard to decide when one group says sharpness is everything and the other says character is more important for faces...
