Tamron 17-28mm F/2.8 Di III RXD vs Voigtlander APO-LANTHAR 35mm f/2 Aspherical

The bottom line

These cover different focal lengths — the Tamron 17-28mm F/2.8 Di III RXD is 17-28mm, the Voigtlander APO-LANTHAR 35mm f/2 Aspherical is 35mm — so they're not really substitutes. Pick by the field of view you actually need: the Tamron 17-28mm F/2.8 Di III RXD for wide-angle zoom, the Voigtlander APO-LANTHAR 35mm f/2 Aspherical for wide-angle.

Choose the Tamron 17-28mm F/2.8 Di III RXD if…

  • You shoot wide — it starts at 17mm vs 35mm for landscapes, interiors and architecture.
  • You want one-lens flexibility — a 17-28mm zoom covers what the fixed 35mm can't reframe.
  • You work outdoors — it's weather-sealed against dust and moisture; the other isn't.

Choose the Voigtlander APO-LANTHAR 35mm f/2 Aspherical if…

  • You want more light and background blur — f/2 is faster than f/2.8, better for low light and subject separation.
  • You prefer a fast, compact single focal length — a 35mm prime over a zoom.
  • You value portability — at 185g (6.5 oz) it's lighter than the 420g (14.8 oz) alternative for travel and all-day carry.
