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.
@Reply #1 - good point! Are you doing mostly full body shots or tight headshots? I totally love the:
- Tamron SP 85mm f/1.8 Di VC USD The stabilization is amazing tho!
Stick with the native Nikon glass, you wont regret it. Honestly though, carrying heavy gear always reminds me of this hiking trip where I brought way too much stuff. I hiked three miles up a ridge just to realize I left my memory cards in the truck. I just sat there eating trail mix and watching the sunset instead. Anyway lol, sorry kinda went off topic there.
Been thinking about your setup since I saw this earlier. Honestly, skip the 105mm for graduation work. It is gorgeous, but that focal length can feel a bit restrictive when you are trying to frame seniors in a park setting.
- The Sigma 85mm f/1.4 DG HSM Art is the winner here. I have put thousands of frames through it on my D850 and the micro-contrast is just superior to the older Nikon 85mm f/1.4G. You get that clinical sharpness that the D850 resolution demands.
- Don't worry about the weight. The balance of that lens on a D850 body is actually great, it helps with stabilization for those handheld shots.
- Focus speed matters for seniors. The Sigma is snappy and predictable. Once you calibrate it with the USB dock if needed, you will have very few missed shots compared to the slower Nikon G-series glass. Native lenses are great, but for the look you want at this price point, the Sigma Art is honestly hard to beat. Just make sure you have a decent strap because it is a long day.
Over the years I have tried many different setups and eventually realized that lab benchmarks dont tell the whole story.
- Spend some time on sites like DXOMark or look at the lens ranking charts. They have side-by-side comparisons that show how much light these things actually let in.
- There was this one series of senior portraits where I used a lens everyone called a masterpiece. On paper it was perfect but in the field the autofocus was just too twitchy. Worrying about the gear took away from the time spent talking to the kids. Moving to a more basic version that just worked every single time was a lifesaver.
- Consistency is everything when you have a client standing there waiting. The hard way was learning that a slightly softer image that is actually in focus is way better than a sharp image that missed the eye. Checking used listings on places like KEH or MPB helps you see how well certain models hold their value which is a good hint at their long-term reliability. Doing this with a Nikon D850 means you have a lot of weight to balance already so definitely keep that in mind!
