Overview
Featuring Fluorite optics that deliver sharper images with less chromatic aberration, the new large-diameter EF 600mm f/4L IS II USM super telephoto lens also takes advantage of magnesium and titanium construction for a lighter weight and a Fluorine coating that keeps soiling, smears and fingerprints to a minimum. Because image stabilization technology in super telephoto lenses may inadvertently over-compensate and interfere with composing and framing distant or moving subjects, the EF 600mm f/4L IS II USM includes an advanced third Image Stabilization mode (Mode 3) that activates IS only when the shutter button is fully pressed. This allows users to pan fast-moving subjects and then activate IS only when it is precisely required. Because all three IS modes give the equivalent effect of up to four extra stops of performance, and because plus the Power Focus mode enables smooth focus change when shooting video, the EF 600mm f/4L IS II USM is ideal for capturing rapid-fire action. Other improvements such as better dust- and waterproofing make the Canon EF 600mm f/4L IS II USM super telephoto lens an ultra high-performance Digital Age tool combining Canon hallmarks of superb ease-of-use with excellent durability.
Features:
- The image stabilizer gives the equivalent effect of a shutter speed four stops faster. Also, a third image stabilizer mode effective for shooting irregularly moving subjects
- Use of fluorite lens elements giving superior definition
- SWC (Subwavelength Structure Coating)
- Using a fluorite coating on the foremost and rearmost lens surfaces allows adhered dirt to be removed more easily than before
- Ultrasonic motor (USM ) for fast , quiet autofocus
- Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT AF)
- An AF stop button to pause autofocus whenever desired
- A power focus mode enables smooth focus change
- A focus preset function for advance storage of focusing positions in memory to allow instantaneous focusing
- Circular aperture for producing beautiful soffocus images
- Can be used with EF1.4x II / EF2X III extenders
- Attachment slot provided for wire-type security lock,located under the cover for the orientation locking knob
- Tight seal structure ensures excellent dustproof and drip-proof performance
- Designed for lighter weight with parts made of magnesium alloy

Image Stabilizer Settings
- Set the STABILIZER switch to ON
- 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 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
- n 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
Power Focus Mode (PF)
1.) With the focus preset switch set to OFF, set the focus mode switch to PF
2.) Rotate the playback ring to change the focus. When the playback ring is rotated in a certain direction, focus changes in the same direction as when the focusing ring is rotated. You can make a 2-step change in focus shift speed depending on the angle that the playback ring is rotated to.
