Overview

A worthy successor to the popular Canon EF 300mm f/2.8 IS, the all-new Canon EF 300mm f/2.8 IS II USM super telephoto lens is lightweight, weighing approximately 13% less than its predecessor, yet offers faster operation, improved image stabilization and superior optics. Incorporating Fluorite elements for improved image quality and reduced chromatic aberration plus a number of advanced coatings to minimize ghosting, flaring, and with a newly developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, the EF 300mm f/2.8 IS II USM is ready to deliver spectacular images in an instant. With a third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed, and giving the equivalent effect of a shutter speed four stops faster, the EF 300mm f/2.8 IS II USM allows for easy panning and is ideally positioned for professional action photography. The EF 300mm f/2.8 IS II USM also features a new security slot for wire-type security locks.

Setting the Lens

• Mounting and Detaching the Lens
• Attaching the Strap -  Thread the end of the strap through the strap mount on the lens and then back through the clasp on the strap. Pull the strap tight and check that there is no slack in the clasp

• Setting the Focus Mode - To shoot in autofocus (AF) mode, set the focus mode switch to AF. To use manual focusing (MF), set the focus mode switch to MF and focus by turning the focusing ring.The focusing ring always works, regardless of the focus mode. To shoot in power focus (PF) mode, set the focus mode switch to PF when the focus preset switch is at OFF. Operating the playback ring enables focus change at a set speed.This is a useful feature for changing focus when shooting movies.
• Switching the Focusing Distance Range - You can set the focusing distance range to 1.9 m/6.2 ft to infinity or 3.5m/11.5 ft to infinity. By setting the suitable focusing distance range, the actual autofocusing time can be shorter

• AF Stop Button - During autofocus operation, you can press the AF stop button to temporarily pause autofocus. If the shutter button is still pressed halfway when the AF stop button is released , autofocusing will continue as before

Focus Preset - By pressing any focusing distance, you can instantly focus at that point even while you are shooting a different in both the AF and MF modes

How to Set:

• Set the focus preset switch to On
• Press the shutter button halfway to focus the distance you want to preset
• Press the focus preset button

Power Focus (PF) Mode - Using the playback ring enables smooth focus change. This is a useful feature for changing focus when shooting movies

• With the focus preset switch set to OFF, set the focus mode switch to PF.
• Rotate the playback ring to change the focus

Image Stabilizer Settings - You can use the image stabilizer in AF and MF mode

• Set the STABILIZER switch to ON - If you are not going to use the image stabilizer function, set the switch to OFF.
• Select the stabilizer mode - MODE 1 : Corrects vibrations in all directions. It is mainly effective for shooting still subjects . MODE 2 : It compensates for vertical camera shake during following shots in a horizontal direction and compensates for horizontal camera shake during following shots in a vertical direction.
• When you press the shutter button halfway, the image stabilizer will start operating - Make sure the image in the viewfinder is stable, then press the shutter button the rest of the way down to take the picture

Tips on Using the Image Stabilizer - The image stabilizer in this lens is effective for hand-held shots under the following conditions

• In Semi-darkened areas such as indoors or outdoors at night
• In locations where flash photography is prohibited such as art museums and theater stages
• In situations where your footing is uncertain
• In situations where fast shutter settings cannot be used
• When panning subjects in motion

• Infinity Compensation Mark - To compensate for shifting of the infinity focus point that results fro changes in temperature. 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
• Hood - The special hoods that come with all these lenses cut out unwanted light and protect the front of the lens from rain,snow and dust

Fitting the Lens Cap

• Reverse the lens hood, slip it over the lens, and tighten the lock knob to fix it in place
• Lift the hook and loop fastener and fit the cap so that the lock knob rides up the slot in the cap
• With the lock knob at the opening in the cap, close the fastener to fix the cap in place as shown
