In the beginning, I bought this zoom lens with various hesitations. After using it for more than half a year, I love this lens too much. The picture quality is better than other 24-105 lenses and even clearer than the fixed focus of Sony Zeiss 35 1.4.
Aperture F4 also has a certain degree of blur. The image quality at 105 focal lengths is not dim at all. The blur is also comfortable and subverts my perception of it.
It’s suitable for taking all types of photos, the only drawback is that it is difficult to focus at night, the camera is Sony A7R4.
