How to Adjust the Focus of Sony a33

Sony a33 can adjust the focal length by rotating the zoom ring on the lens.

SLR/single camera focus adjustment is to rotate the zoom ring on the lens (the red ring in the above picture) and use the focus ring to focus manually (the blue line/basket in the above picture).

Sony a33 is a single camera released in the autumn of 20 10. Adopt APS-C "Exmor" high-definition CMOS sensor, effective pixel 1420, adopt live view when shooting, and use full-time phase detection autofocus system when shooting photos or videos. The main parameters of Sony a33 are:
