do this:
get a tripod
set your camera apereture priority f22 (or as small as your lens will go)
set your camera on timer delay so theres no vibration from shutter press
set your camera on mirror up so theres no
mirror vibration
set iso to 100 or 200
use manually focus to
now take a picture of a row of beer bottles or something you can stand in a long line. shoot down the line and manually focus in the middle
now do the same for all apertures back to f1.4 in 1 ev stops
check your photos. youll now see quite clearly how sharp the lens can be at what apereture
youll have no
vibrations to interfere
btw i do this whenever i get a new lens to play with
