So I finally pulled the trigger on a used D850 after shooting with a D7200 for forever and honestly the difference is insane but now my old lenses just aren't cutting it. I’ve got a couple of graduation shoots coming up at the local park in about three weeks and I really want that creamy bokeh look for the seniors but I am totally stuck on which prime to go for.
I've been looking at the Nikon 85mm f/1.4G and the Sigma 85mm Art. I found a deal on the Nikon for like $900 used but everyone says the Sigma is way sharper even if it is a literal brick to carry around all day. Then there is the 105mm f/1.4E which people rave about but it might be way over my budget of $1300 unless I find a crazy deal. I’m mostly worried about the autofocus speed because the seniors move around a lot more than you'd think lol.
Is the Sigma Art worth the extra weight on an already heavy D850 or should I just stick with the native Nikon glass? Or is the 105mm just so much better that I should sell a kidney to get it...
TL;DR: Grab the Sigma 85mm f/1.4 DG HSM Art for Nikon F. Its a beast to carry but that D850 sensor really needs the sharpness it brings. In my experience, the older Nikon AF-S NIKKOR 85mm f/1.4G has beautiful character but the autofocus feels a bit sluggish for active seniors. The Sigma is way more reliable for those candid walk-and-talk shots and fits your budget perfectly.
