Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO vs Sony E 10-18mm f/4 OSS

The bottom line

These cover different focal lengths — the Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO is 45mm, the Sony E 10-18mm f/4 OSS is 10-18mm — so they're not really substitutes. Pick by the field of view you actually need: the Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO for short-telephoto / portrait, the Sony E 10-18mm f/4 OSS for wide-angle.

Choose the Laowa Aksen 45mm f/2.8 1-5x Ultra Macro APO if…

  • You want more light and background blur — f/2.8 is faster than f/4, better for low light and subject separation.
  • You need more reach — it goes to 45mm vs 18mm for distant subjects, wildlife and sport.
  • You shoot close-ups — 5x magnification gets you true macro the other can't.
  • You prefer a fast, compact single focal length — a 45mm prime over a zoom.

Choose the Sony E 10-18mm f/4 OSS if…

  • You shoot wide — it starts at 10mm vs 45mm for landscapes, interiors and architecture.
  • You want one-lens flexibility — a 10-18mm zoom covers what the fixed 45mm can't reframe.
  • You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
  • You value portability — at 225g (7.9 oz) it's lighter than the 599g (1.32 lb) alternative for travel and all-day carry.
