FE 70-300mm F4.5-5.6 G OSS
84 x 84 x 144 mm.
- DxO Mark
It achieved an overall DxOMark lens score of 26 points. That’s an excellent score for a lens like this. It has high sharpness throughout the zoom range, although like most zooms, it’s a better performer at the shorter end. Nevertheless, it is very usable at 300mm even wide-open — but stopping down slightly will reward you.[...] Vignetting, distortion, and lateral chromatic aberration are all relatively low.

You are buying such lenses primarily for its potential at the very long end of the range which is where the performance may not be bad but it certainly doesn't reflect the promises of a G-class lens nor its high price tag. Now that being said - the center quality is still very good at 300mm. Lateral CAs are low. The distortion figures are well controlled for such a lens even without distortion correction. The quality of the bokeh is a bit of a mixed bag.
