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
To ensure that you use the lens’ functions effectively, it is recommended that you shoot in the following
conditions.
• Use an EOS camera with about 100% viewnder visibility
• Use Live View (with onscreen grid)
• Use an external monitor
• Use a tripod
• Use a matte with grid focusing screen
• Use a stand-alone exposure meter
Since only a hood is not very effective in cutting off the harmful rays entering the lens, also using a piece of
cardboard is recommended.
If using Digital Photo Professional to perform lens correction (lens aberration correction, Digital Lens
Optimizer, etc.)*, shooting with rotation or TS rotation locked or at a click position is recommended.
* Supported cameras: EOS 6D Mark II (As of August 2017)
