Ive been going down a total rabbit hole for weeks now and honestly my head is spinning trying to pick a prime lens for my D850. I keep seeing people rave about the Sigma 35mm f1.4 Art saying its the sharpest thing since sliced bread but then I go on other forums and everyone is complaining about autofocus issues and saying the Nikon 35mm 1.4G is better for color even if its technically softer. I just want something that is tack sharp from edge to edge because I have a gallery show in Seattle coming up next month and Im printing big, like 24x36 big, so I cant have any mushy corners or chromatic aberration ruin everything.

Everything I read contradicts the last thing I read and its driving me crazy. I need to make a decision like yesterday so I can actually get out and shoot the landscapes I need.

• Budget is around 1000 dollars maybe up to 1200 if its a game changer
• Must be a prime lens, looking at 35mm or maybe a 50mm
• Needs to actually handle the 45 megapixels without looking blurry
• Good build quality since I hike a lot in the PNW

Is the Sigma actually the king of sharpness or am I gonna regret not sticking with name brand Nikon glass for the reliability? Or is there some Zeiss or Tamron option I totally missed while staring at charts all night...
