8. Depth-of-Field Scale 9. Infinity Compensation Mark Distance scale Depth-of-field scale Distance scale Distance Infinity index compensation mark Illustration shows TS-E50mm f/2.8L MACRO. The depth of field is the distance in front of and behind the plane of focus on the subject that appears sharp. The depth of field is indicated by the area between the depth-of-field scale lines below the distance scale. The numbers on the scale are aperture settings. To compensate for shifting of the infinity focus point that results from changes in temperature, there is a margin at the infinity (∞) position. The infinity position at normal temperature is the point at which the vertical line of the distance scale L mark is aligned with the distance index. OOThe depth-of-field scale is only valid when the lens is not tilted or shifted. OO The depth-of-field scale is an approximate indicator. OO For accurate manual focusing of subjects at infinity, look through the viewfinder or look at the magnified image on the LCD screen while turning the focusing ring. ENG-28
