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...
Had a moment to think about this more and I totally get the anxiety. I went through the same thing with my D850 when I started doing larger gallery prints for a local show. You really have to be careful because that sensor shows every single flaw in the glass, especially when you're blowing things up to 24x36. I ended up going a slightly different route because I was worried about the Sigma's autofocus issues too. For hiking in the PNW, you need something that wont fail when it gets a bit damp or dusty.
- Tamron SP 35mm f1.4 Di USD: This is the one I finally settled on and I am super happy with it. It was built for their anniversary and it is honestly sharper than the Sigma Art in the corners. Plus, the weather sealing is legit for our weather out here.
- Sigma 35mm f1.4 DG HSM Art: Like you heard, it is a sharpness king in the center, but the consistency just wasnt there for me. If you are on a tripod using manual focus for landscapes its great, but for anything else it can be a headache.
- Nikon AF-S NIKKOR 35mm f1.4G: Great colors, but yeah, it shows its age on a 45MP sensor. I found it a bit soft for those big prints compared to the modern third-party options. Tbh the Tamron is the safest bet if you want that edge-to-edge clarity without the gamble. It handled my last big project perfectly and I havent had any complaints about the build quality after a year of heavy use... it just works well every time.
Just caught this thread and figured id chime in with some actual specs for that D850 sensor. If you really want edge-to-edge resolution for 36-inch prints, you might want to look past the older Sigma 35. The Tamron SP 35mm f/1.4 Di USD actually out-resolves almost everything in its class and it has way better weather sealing for your PNW hikes. Heres why it wins on a 45mp body:
- Better chromatic aberration control than the Nikon 1.4G
- Higher contrast at the corners compared to the Sigma Art
- Fluorine coating makes cleaning mist and dust off the front element way easier when you are out in the field Another sleeper hit is the Sigma 40mm f/1.4 DG HSM Art. Its basically a cinema lens in a stills body. It is heavy as a brick, but honestly, it is the sharpest prime I have ever tested on a high-res Nikon body. It usually floats around 800 or 900 dollars now so its well under your budget limit. Good luck with the Seattle show, hope it goes well.
Works great for me
Honestly I spent ages obsessing over MTF data and lp/mm resolution before my last big gallery show...
- Just go with Sigma tho
- Their prime glass is incredibly sharp
