I just upgraded to a D850 for a wedding I have in literally two weeks and Im freaking out a bit because my old zooms just arent cutting it on this sensor. Everything looks soft when I zoom in to 100 percent. I spent hours reading reviews and everyone keeps mentioning the Sigma 35mm Art or the Nikon 50mm 1.8G but the opinions are all over the place. My logic was that the 50mm would be a cheap safe bet but then I read a bunch of threads saying the D850 sensor is so demanding that older or cheaper glass just looks like trash on it.

So then I looked at the Nikon 35mm 1.4G but that price tag is really steep for something that people say has slower autofocus compared to the newer stuff. I need something sharp enough to handle the 45.7 megapixels because Im shooting this ceremony in Seattle and the lighting is probably gonna be dark and moody. I have about 1200 dollars left in my budget for one really solid prime lens. Should I go for the Sigma Art line or stick with Nikon Gold Ring glass? Some people say the Sigma has major focus hunt issues on Nikon bodies but the sharpness is supposedly way better for high res sensors. Im just stuck between wanting that crazy detail and needing something that actually hits focus every time...
