Review on Sigma 24 70Mm 2 8 Lens Nikon by Hideo Masuda ᠌

Focusing on all points is excellent except for the top left (flies by). When turned on stabilizer there is twitching of the image in the viewfinder, but this is only when I release the focus button and continue to observe what is happening in the viewfinder. It is noticeable that the stub seems to stop working too abruptly and inside there is a "shift" of the lens for a fraction of a second. Because of this, the "bouncing" of the picture occurs. Tell me, do all lenses with stubs behave this way?
