Sharpness at 9mm

Our sharpness tests were conducted using a Fujifilm X-T3 camera mounted on a tripod. The camera’s shutter release was also set on a timer-delay to avoid any possible camera shake. The test subject was shot using ambient lighting, hence some colour and contrast variation is to be expected between apertures.

Both centre and corner sharpness are impressively high wide-open at f/2.8 and outstanding between f/4-f/8. At f/11 sharpness starts to fall off a litte, becoming progressively worse at f/16-f/22.
