p.1 #1 · p.1 #1 · Hi : ) !!! - Fuji lens - Outer edges of lens, show 1,900 lines - What?? | |
Hi,
Fuji manufactures a lens, the XC 16-50 mm, it is not an XF lens!
In this article the reviewer talks very well about it! He says:
I used Imatest to see how sharp the 16-50mm is when paired with the 16-megapixel X-A2. At 16mm f/3.5 it scores 2,051 lines per picture height on a center-weighted sharpness test, better than the 1,800 lines we look for in a photo. Performance is consistent across the frame, with even the outer edges showing 1,900 lines. Stopping down doesn't do much to improve image quality—even at f/8, the lens shows 2,090 lines. There's a bit of barrel distortion here, but it's just barely noticeable to the eye and can be corrected in software with ease if desired.with even the outer edges showing 1,900 lines

When he mentions 'the outer edges', does he refer to the image's corners, or to the outer edges
of the center-weighted measuring he took?
How sharp is it to have 1900 lines at the image's corners, how can I better understand this 'lines concept' that is used to define sharpness?
How much better with regard to sharpness is the Fujinon 16-55 mm. f/2.8 ??
Thank you, kind regards,
