Which prime lens is best for portrait photography on Nikon D850?

The Nikon AF-S NIKKOR 85mm f/1.4G is unfortunately a letdown on the D850. It shows way too much purple fringing and the AF is pretty sluggish for moving targets. While the Sigma 105mm f/1.4 DG HSM Art is sharp, it's a literal brick for a full wedding day.

• Nikon has dated AF motors
• Sigma causes massive wrist fatigue
• D850 sensor is too demanding for older optics I'd honestly recommend the Sigma 85mm f/1.4 DG HSM Art instead. It's the best balance for that budget.

Quickly jumping in here since I went through the exact same headache with my D850 a while back. I spent big on the Nikon AF-S NIKKOR 85mm f/1.4G expecting perfection, but unfortunately, it just didnt hold up. The micro-contrast was pretty weak compared to what that 45MP sensor can actually pull. It is a bummer when you spend that much and the glass feels dated... the resolution just isnt there for modern bodies. Honestly, Id skip those and look for a used Tamron SP 85mm f/1.8 Di VC USD Nikon F. I know its only f/1.8, but it has built-in stabilization which is a lifesaver when youre exhausted at the end of a long day. Plus, you can find them for around 450 bucks used. If you really need that f/1.4 speed, the Sigma 85mm f/1.4 DG HSM Art Nikon F is way more manageable than that 105mm brick and fits your budget. Dont overspend just to be disappointed by soft corners.

• Honestly, if weight is a worry for a long wedding, Ive been super happy with the Tamron SP 85mm f/1.8 Di VC USD. Having stabilization is a total lifesaver when youre tired. Another great practical choice is the Nikon AF-S NIKKOR 85mm f/1.8G. Its way lighter than those heavy 1.4 beasts and still plenty sharp for the D850 sensor. Save your back and some cash!
