Thank you for purchasing this Canon IS USM lens.
Canon's EF300mm f/2.8L IS USM, EF400mm f/2.8L
IS USM, EF500mm f/4L IS USM and EF600mm
f/4L IS USM are high-performance super-telephoto
lenses, for use with EOS cameras. They are
equipped with an image stabilizer effective for
hand-held shooting at slow shutter speeds.
"IS" stands for Image Stabilizer.
"USM" stands for Ultrasonic Motor.
a Handling Cautions
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.
Features
1. Use of fluorite and UD lens elements giving
highly superior definition.
2. Dual mode image stabilizer with up to two-stop
shutter speed conversion.
3. USM for fast, quiet focusing.
4. Manual focusing available in autofocusing mode.
5. Can be used with EF1.4× II or EF2× II extenders.
6. An AF stop button to pause AF functions
whenever desired.
7. A focus preset function for advance storage of
focusing positions in memory to allow
instantaneous focusing.
8. Tight seal structure ensures excellent dust-proof
and drip-proof performance.
9. Lightweight design using magnesium alloy for the
main casing components.
