First NiSi 15mm f/4 Review

Phillipreeve posted the first review of the Nisi 15mm f/4, which you can read here. Below is a brief summary of his findings:

“I found the NiSi 15mm 4.0 to be a useful lens that did not disappoint in the field. I especially like that it was fully usable at f/4.0 (very little field curvature) and that vignetting at this aperture is comparably moderate.”

good
  • across frame sharpness and contrast
  • coma correction
  • vignetting (f/4.0)
  • sunstars
  • handling/build quality
  • minimum focus distance
average
  • vignetting (stopped down)
  • CA correction
  • distortion
  • size/weight
not good
  • flare resistance
  • no exif data
  • slight color cast in the corners
