Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras

IS dramatically reduces image blur caused by camera shake. The EF 70-300mm f4-5.6 IS USM features Canon's latest 3-stop IS, a one-stop improvement over its predecessor.

This allows shutter speeds up to three stops slower than would otherwise be possible, with no perceptible increase in image blur.

Photographers normally shooting a 300mm frame handheld at 1/500 second can obtain the equivalent result with a shutter speed of just 1/60 second, vastly extending options in low-light conditions.

Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis.

This alters the light path, returning the image to its correct position on the sensor or film plane.

The EF 70-300mm f4-5.6 IS USM provides 2-mode IS for shooting immobile subjects. Mode 1 stabilizes the image along both the horizontal and vertical axes.

For shooting while panning to follow a moving subject, Mode 2 turns off correction in the panned direction and prevents the effect of dragging the subject back through the frame.

IS switches off automatically when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations.

The best asset that digital lenses bring with them is the clarity and quality of images produced.

Since natural photography mostly involves talking pictures at all times of the day, digital lenses prove very effective during odd timings.

Some digital lenses like the Canon Wide Angle Lens ensure that the photographer gets a wide shot and does so even standing at a considerable distance.

The shot is made to look very natural and no sign of blur can be spotted on the final layout.

Zoom lenses can give you flexibility and versatility all in one lenses.

When buying a zoom lens try and get one that is made of glass and is the fastest you can afford, you will not regret it.

Prime Lens should possess a longer type of zoom lens or a lone focal length between 35mm up to 85mm.

I bought this lens as a replacement for the earlier 75-300mm IS lens. I was generally happy with that lens, but it had definite limitations - I needed to shoot at f8 or f11 and bump up the ISO to get a decent shutter speed.
This new version seems sharp at full zoom even wide open, allowing me to use a lower ISO setting. Size is similar to older version, but the IS seems more effective - looking through the lens when it kicks in you can actually see the image become more stable and less shaky. I got this over the Canon 70-200 f4 L because of the extra reach, smaller size (slightly) and the images I've seen from both are very similar.
UPDATE: There have been reports of soft images when using this lens in a verticle orientation - however I have not experienced this on my copy. I'm happy to say that after months of using this lens, I still consider it great.

This lens is a great all around lens. It takes excellent still photos and it does a great job on action shots like at my kids softball games. We went from a 18-55mm zoom lens and could not believe the difference. We looked into some of the cheaper lenses like Tamaron and some of the others but heard some things about them that changed our thoughts and made us go with the Canon brand. I dont regret it for a minute. I only wish that Canon would offer this lens STANDARD with the lens hood.

The micro USM motor found in the EF 70-300mm f4-5.6 IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivaled speed and near-silent operation.

Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. A high-speed CPU and optimized AF algorithm result in a significant increase of AF speed compared to that of its predecessor.

A zoom ring locking mechanism is provided that locks the zoom at the wide-angle setting.

This ensures that the lens is carried or stored in its most compact position, preventing possible damage caused by the lens extending and hitting obstacles when being carried mounted on a camera with a strap.
