Choose the OM System M.Zuiko Digital ED 75-300mm f/4.8-6.7 II if…

  • You need more reach — it goes to 300mm vs 42mm for distant subjects, wildlife and sport.
  • You want one-lens flexibility — a 75-300mm zoom covers what the fixed 42mm can't reframe.
  • You like close-focus work — 0.23x magnification vs 0.1x.

Choose the Panasonic LEICA DG NOCTICRON 42.5mm f/1.2 if…

  • You want more light and background blur — f/1.2 is faster than f/4.8, better for low light and subject separation.
  • You shoot wide — it starts at 42mm vs 75mm for landscapes, interiors and architecture.
  • You prefer a fast, compact single focal length — a 42mm prime over a zoom.
  • You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
