Review on 📸 Sigma 105mm F2.8 DG DN Macro Art (Sony E-mount): Superior Optics for Stunning Macro Photography by Alan Massey

Received the lens about a week after it was released. Very densely built. There is nothing to complain about in terms of optical quality. The autofocus motor is pretty fast, but when you focus from infinity to the closest autofocus, you can hear the autofocus motor whine a bit. The AF is also not crucial in low light conditions, but good in normal lighting. Note: Another reviewer here said that the aperture can only be adjusted in the lens. That is not true. He forgot to turn the aperture all the way to "A" so you can adjust the aperture in the camera.
