Sony FE 90mm f/2.8 Macro G OSS review – Image quality: Resolution

Looking at the chart, there are two things that stand out. The first is that there is only a small difference in centre sharpness when shooting at f/2.8 and at f/8. Second, at f/8 the resolution at the centre and edge is virtually identical, as can be seen in the image on page 52. This is an impressive performance, and means that at its best the 90mm macro is one of the sharpest lenses we have tested.
