Sharpness at 30mm

For this test, the Fujifilm XF 30mm F2.8 R LM WR Macro lens was attached to a Fujifilm X-T5 body, which was in turn mounted to a sturdy tripod. Exposure delay mode was activated. Tonal and colour variance across the crops are due to change in natural light during the session.

The full frame at 30mm

Centre sharpness is very good wide-open at f/2.8 and outstanding all the way through to f/16, with f/22 being affected by diffraction.

The edges are just as sharp as the centre, with the best results again obtained from f/4 through to f/16.
