Seeking recommendations for a good wide angle zoom for Nikon cameras (Z9 and D850). I don’t anticipate a ton of low light situations with outdoor landscapes but I would like to have the option of doing street photography in the evenings or early mornings as well as some situations where there is a play of shadows. Something that won’t break the bank but is a reasonable balance of price and quality.
i understand You want Wide a zoom, for Shadows early morning etc street photography, you will with the experience want low light performance that i bet you haven't discovered the need for just yet, using a good wide lens really inspires and makes you explore creativeness, with F2.8 in a Zoom you will need far less ISO. Its not about shooting at F2.8 that matters so much its just that the glass gather tonnes more light = less iso=sharper cleaner images at lower shutter speeds...ticks a lot of boxes......... yes.
Remember your using a D850 and a Z9 so you need something that really can deliver.
F2.8 FX glass is so cheap and you want it fit both cameras, Z versions are chronically over priced, for the little extra you may get out of them, you can pick up a 24-70 2.8 G and 14-24 2.8 G for under $1000 each used, KEH has heaps as does B and H, they both take filters easily the 14-24 you will need a holder if in fact you want filters, a wide zoom is addictive so be careful.
They are both PROFESSIONAL killer lenses, however if your going to go for a 24-70 you at some time will want to go wider, i do like the Tamron 24-70 2.8
current model, it also has VR if that's what you need, also used it will be cheap, its sharp and will do the job nicely the VR is better than most things Nikon has to offer.
Remember you mentioning you want a Zoom.
"Something that won’t break the bank but is a reasonable balance of price and quality" short list 14-24 2.8, 16-35 F4 with caveats, 24-70 2.8 in Nikon or Tamron with VR.
For the price of a new 2.8 Z version you can buy a 14-24 and 24-70 or 16-35 with money to burn..........if you want small and light then down comes the price yes and you get into the F4 f5.6, you will spend time and money to only end up back to 2.8 glass.
Also things depend on you doing documentary shots or you get addicted to doing creative perspective shots that wow hence 14mm that really goes deep and far for landscape or city scape.
16-35 F4 is excellent, cheap as, its an all round travel landscape zoom 77mm filters like the 24-70, ts super sharp in the middle around 20% more than the 14-24 but softer in the corners, and not quite the ticket for astro or super low light, it also vignettes and with filters may need to go to 19mm to clear vignetting.
If you want lower light indoor performance the any F2.8 carry's the goods.
I use my 14-24 or 16mm 180 degree fish eye, or the 24-70 or the 50mm Ziess.
The 14-24 i get in close fast dynamically wide perspective full of wow or i use it for seascape landscape on a tripod.
Hope it all helps.
