General Precautions Handling Precautions ●● If the lens is taken from a cold environment into a warm one, condensation may develop on the lens surface and internal parts. To prevent condensation in this case, first put the lens into an airtight plastic bag before taking it from a cold to warm environment. Then take out the lens after it has warmed gradually. Do the same when taking the lens from a warm environment into a cold one. ●● Please also read any lens related handling precautions listed in your camera's instruction manual. Shooting Precautions ●● Note that there are cases in which the white ring on the front of the lens may be reflected into photographs if the lens is held close to reflective objects (glass surface on wristwatches, for example), even if the Macro Lites are not illuminated. This can be avoided by attaching the hood when taking photographs. ENG-3
