It’s softer from spherical aberration wide-open, and built like a tank for a lifetime of great pictures.




f/1.4: Spherical aberration lowers contrast. A lot of coma in the corners making them quite soft. Falloff.


f/2: Much better. Falloff much less.


f/2.8: Quite good, falloff and coma gone. Sharp all over.




It has the typical mild to moderate barrel distortion of all of Nikon’s 50mm f/1.4 manual-focus lenses.


Plug these figures into Photoshop’s lens distortion filter to correct the distortion. These aren’t facts or specifications, they are the results of my research that requires a lot of data collection and computation.
