cameras do not have the direct manual focus function. If your camera has this
function, this restriction is explained in the section on focusing, in your camera's
instruction manual.)
This manual is for use with several different lenses.
This lens is designed for A-mount, which can be used on Sony α cameras.  The focusing ring can be rotated slightly past the infinity to provide accurate
focusing under various operating temperatures. Do not rotate the focusing ring
all the way to the end when focusing manually even at infinity. Look through
the viewfinder, etc., and set the focus precisely. (50mm F2.8 Macro,100mm F2.8
