In my experience with the D850, it really demands glass that can resolve tiny details, especially for fashion work where skin texture is everything. Before I dive into specific gear, how much floor space are you actually working with in that NYC studio? If you're cramped, that 105mm is gonna be a nightmare for full-body shots. Honestly, over the years I've found that the 1.4G is starting to show its age on these newer high-res sensors. If you want something that balances weight and sharpness without the Sigma bulk, check these:

• Tamron SP 85mm f/1.8 Di VC USD
• Seriously underrated. The vibration compensation is a lifesaver for handheld fashion shoots.
• Nikon AF-S NIKKOR 105mm f/1.4E ED
• You can find these used for under $1500 now. It's the gold standard for compression. The Tamron is a total steal and leaves you budget for a backup lens or a rental if you need it. Just make sure to use the D850 auto AF fine-tune feature... it makes a massive difference for hitting focus wide open.

> Is the 85mm 1.4G still the king for this body or is there something I'm missing that works better with the autofocus system on the 850? Saw this earlier but just now getting a chance to reply. Honestly, i hate to be the one to say it, but the Nikon AF-S NIKKOR 85mm f/1.4G really isnt the king anymore, especially on a beast like the D850. I had some major issues with mine... the purple fringing is just nasty when you're shooting high-contrast fashion stuff, and the autofocus feels kinda sluggish compared to modern glass. It is disappointing because it was so expensive back then, but it just doesnt resolve well enough for 45 megapixels wide open. The Nikon AF-S NIKKOR 105mm f/1.4E ED is fantastic but yeah, finding one under $1500 that isnt beat to hell is tough right now. Plus it is a specialized beast and if you are in a tight NYC studio, you might find yourself hitting the wall trying to fit a full-body shot in. Since you're worried about weight and budget, you might actually wanna look at the Tamron SP 85mm f/1.8 Di VC USD. It is way better than i expected. It is sharp as a tack and having vibration compensation for handheld shots is honestly a huge deal when you are doing long fashion sets and getting tired. If you want to stay native, the Nikon AF-S NIKKOR 85mm f/1.8G is actually sharper than the 1.4 version on these high-res sensors, which is crazy to think about. It is super light too. Tbh, check out the LensRentals blog or look at some real-world MTF charts on DXOMARK. They have a specific breakdown for the D850 sensor that might save you a lot of headache before you drop the cash. Dont let the gear panic get to you tho, you got this!

tl;dr: The Sigma Art is the sharpest for that sensor but weighs a ton, while the 105mm is incredible if you actually have the room to move back. I've been shooting with the D850 since it launched and yeah, it definitely exposes every weakness in your glass. Going from the Nikon AF-S NIKKOR 24-70mm f/2.8G ED to a prime is a huge jump in quality but also a bit of a shock to the system. I've used the Nikon AF-S NIKKOR 85mm f/1.4G for years and while it has a certain magic to the rendering, it can struggle a bit with the sheer resolution of the 850 if you're looking for clinical perfection at the edges. The Sigma 85mm f/1.4 DG HSM Art for Nikon F is a different beast entirely. It's pin-sharp, but honestly, it feels like carrying a literal brick around. If you're doing a full day of fashion, your wrists are gonna hate you. The Nikon AF-S NIKKOR 105mm f/1.4E ED is basically the gold standard for that body, but the focal length is really specialized. Before you pull the trigger, how much space do you actually have in the studio for this NYC shoot? If you're doing full-body shots, that 105mm might have you literally pinned against the back wall. Also, what kind of lighting setup are you planning? Are you gonna be shooting wide open at f/1.4 most of the time or stopping down? Knowing that would definitely change which way I'd lean for a high-res body like yours.

Would love to know this too

Yep, this is the way

@Reply #7 - good point! This thread has really covered the main trade-offs. To summarize what we have so far: the older 85mm 1.4G suffers from chromatic aberration on the D850, the Sigma Art is excellent but incredibly heavy, and the 105mm 1.4E requires a lot of working distance. If you want a safe, reliable option that fits your budget, I highly recommend looking at the Nikon AF-S NIKKOR 85mm f/1.8G. I have used this lens on my D850 for editorial work and have no complaints. It is surprisingly sharp wide open, autofocuses quickly, and avoids the calibration headaches of third-party lenses. At around $479 retail, it leaves you plenty of budget for other gear while delivering the professional results you need for the NYC shoot.

Re: "@Reply #7 - good point! This thread has..." - honestly, I have to jump in here because I think you are all sleeping on the Tamron SP 85mm f/1.8 Di VC USD. I used to be obsessed with the Nikon 1.4 glass, but after dealing with constant focus micro-adjustments on the D850 with the 85mm 1.4G, I had issues with sharpness consistency that drove me insane. It just wasn't as good as expected for such an expensive piece of kit. Here is why you should save your money:

• The Tamron is significantly cheaper than the Nikon 1.4E or Sigma Art, leaving you room for better lighting gear.
• The Vibration Compensation (VC) is a life saver if you are shooting handheld for long NYC fashion shifts.
• Optically, it resolves the 45MP sensor way better than the older 1.4G without that purple fringing. Don't get me wrong, the 105mm is a dream lens, but for studio space constraints, the 85mm focal length is just more practical. Unfortunately, chasing that f/1.4 aperture often leads to more focus errors than it's worth. Trust me, the f/1.8 gives you way more keepers.

Like someone mentioned, the 105mm is incredible glass but yeah, it can be a tight squeeze in some of those smaller NYC studios. Ive been using the Tamron SP 85mm f/1.8 Di VC USD for a while now and honestly im so satisfied with how it handles the high res sensor. Its one of the sharpest lenses ive ever owned and resolves detail way better than the old Nikon 1.4G without that nasty purple fringing. The best part is the built-in VC. It really helps when you start getting tired during a long session and your hands start shaking a bit. I actually saved a ton of money buying it used and then grabbed the Tamron Tap-in Console for Nikon to fine-tune the focus myself at home. It takes a little patience to get the calibration right but once its dialed in, the autofocus on the D850 is basically perfect. Youll definitely stay way under your 1500 budget too. If you go this route and need help with the software, let me know!

Late to the party but this whole thread is 💯. Glad I found it.
