Canon EF 600mm f/4 L IS III telephoto lens

Canon EF 600mm f/4 L IS III professional telephoto lens

A super-telephoto lens for professional sports and wildlife photography. This completely redesigned Canon EF 600mm F4L IS III USM is the world's lightest 600/4 lens.

• Over 20% lighter (3050g vs 3920g)
• Better usability and focus further back
• More powerful 5-stop IS image stabilization (previously 3.5)
• New coatings , new Super UD lens element
• Closest focusing distance 4.2m (previously 4.5m)
• Electronic manual focus and two focus memory slots

The biggest change in the lens is the weight reduction of almost a kilo. There is one large lens element at the front of the lens, but most of the lenses and the focus motor have been moved to the back of the lens. Due to the rearranged lens elements, the center of gravity of the lens is closer to the camera. Due to its lightness and the location of the center of gravity, the lens is uniquely easy to handle as a super telephoto. The center of gravity is especially helpful when using a monopod, as most of the weight is right at the tripod mount.

We have tried the new lens and the difference is really noticeable compared to the old one. The lightness and the change in the center of gravity make shooting faster and it is easier to react quickly to the movement of the subjects as the lens does not generate torque in the same way as before.

The lens' focusing elements are also located further back, and Canon has switched to electronic manual focus. Since the focus is not mechanical, the lens offers three focus ring speeds. Unlike previous Canon super-telephoto lenses , the Focus Preset function ring can be turned in both directions and now two different focus distances can be stored in memory . The electronic focus ring works very similarly to the previous ones, meaning the feel is good and the ring is suitably damped.

The optical construction consists of 17 elements in 13 groups, with two fluorite lenses and one super UD lens element for distortion correction. The lens elements have been upgraded with ASC (Air Sphere Coating). This multi-layer coating technology reduces flare and ghosting more effectively than traditional techniques. The difference between the coatings is especially noticeable when shooting against backlight and if there are bright point-like light sources in the image area.

The Canon EF 600mm III is weather and dust-resistant to the same standard as professional L-series lenses. It also features a new fluorine coating on the front and rear lens elements that repels dirt and makes cleaning easier . The lens also has a new heat-reflecting surface treatment, the difference to the old one is immediately noticeable in the whiter color tone upon first use.

Canon recommends using the new III series teleconverters with this lens.
