Choose the Tamron 70-300mm f/4.5-6.3 Di III RXD (Nikon Z) if…

  • You need more reach — it goes to 300mm vs 35mm for distant subjects, wildlife and sport.
  • You want one-lens flexibility — a 70-300mm zoom covers what the fixed 35mm can't reframe.
  • You like close-focus work — 0.32x magnification vs 0.15x.

Choose the Viltrox AF 35mm f/1.8 II EVO (Nikon Z) if…

  • You want more light and background blur — f/1.8 is faster than f/4.5, better for low light and subject separation.
  • You shoot wide — it starts at 35mm vs 70mm for landscapes, interiors and architecture.
  • You prefer a fast, compact single focal length — a 35mm prime over a zoom.
  • You value portability — at 375g (13.2 oz) it's lighter than the 545g (1.20 lb) alternative for travel and all-day carry.
