Laowa 4mm f/2.8 Fisheye MFT vs Panasonic LUMIX G VARIO 12-32mm F3.5-5.6

The bottom line

These cover different focal lengths — the Laowa 4mm f/2.8 Fisheye MFT is 4mm, the Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 is 12-32mm — so they're not really substitutes. Pick by the field of view you actually need: the Laowa 4mm f/2.8 Fisheye MFT for wide-angle, the Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 for wide-angle.

Choose the Laowa 4mm f/2.8 Fisheye MFT if…

  • You want more light and background blur — f/2.8 is faster than f/3.5, better for low light and subject separation.
  • You shoot wide — it starts at 4mm vs 12mm for landscapes, interiors and architecture.
  • You prefer a fast, compact single focal length — a 4mm prime over a zoom.

Choose the Panasonic LUMIX G VARIO 12-32mm F3.5-5.6 if…

  • You need more reach — it goes to 32mm vs 4mm for distant subjects, wildlife and sport.
  • You want one-lens flexibility — a 12-32mm zoom covers what the fixed 4mm can't reframe.
  • You shoot handheld or on an unstabilised body — it has optical stabilisation, the other doesn't.
  • You use filters or shoot video — internal zoom keeps length and balance constant.
