First NiSi 15mm f/4 Review

By Louis Ferreira | Published: January 15, 2021

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
