◆ Significantly lighter weight While maintaining the same high image quality, durability, and robustness as the well-established previous model, it is significantly lighter than the previous model. Achieved weight reduction. The mass of the EF600mm F4L IS III USM is approximately 3050g, which is approximately 870g (more than 20%) lighter than the previous model's approximately 3920g. The optical system has been completely renewed. By utilizing special optical materials, we have adopted a newly designed lens configuration in which the optical system from the second lens onwards is concentrated at the rear. The mechanical structure has been completely redesigned by optimizing the mechanism due to the electronic focus ring. Carbon-reinforced magnesium alloy is used for lens barrel components. Newly designed lightweight "IS unit".

◆ High image quality and high reliability suitable for the "L Lens" series Adopts a new optical design with 17 elements in 13 groups, including special optical materials such as 2 fluorite lenses and 1 super UD lens. Achieves high image quality equivalent to conventional models while being lightweight. In addition to optimizing lens placement and coating, we have adopted a special coating called ``ASC (Air Sphere Coating)'' that has a significant anti-reflection effect against light that enters the lens at an angle close to perpendicular to it. This suppresses flare and ghosting, which cause image quality deterioration. We have adopted a heat-shielding paint that increases the reflectance of infrared rays contained in sunlight, and a lens barrel design that suppresses heat conduction. This suppresses the temperature rise of the lens, even when shooting for long periods under the scorching sun, such as during outdoor sports. The mount, switch panel, and focus ring are dust-proof and drip-proof*. Fluorine coating is used on the front and rear surfaces of the lens to prevent oil and water droplets from adhering to it. Oil and other substances adhering to the lens can be easily removed with a dry cloth without using solvents. *Although the structure is designed to be dust-proof and drip-proof, it cannot completely prevent the intrusion of dust, water droplets, etc.

◆ Improved convenience for comfortable shooting Improved processing speed with the latest microprocessor, adoption of a high-performance vibration gyro, and construction of an optimal algorithm, the shutter speed is equivalent to 5 steps faster. Achieves blur correction effect. Significantly improved from the 3.5 steps of the previous model. The focus ring has been changed from the mechanical linkage type of previous models to an electronic type. As a result, a new feature, the "Manual Focus Speed ​​Switch", has been added that allows you to select the manual focus speed from three levels. Equipped with a "focus preset" that allows you to quickly focus on up to two preset points. The number of points that can be selected from the previous one has been increased to improve convenience. Equipped with three types of "IS modes" that can suppress camera shake depending on the shooting situation. "IS mode 1" is suitable for shooting still subjects, "IS mode 2" is suitable for panning shots essential for motor sports and railway photography, and "IS mode 3" is suitable for shooting rapidly moving subjects such as sports. Can be used differently. Equipped with an AF stop button, power focus function, and security slot, while inheriting the operability of the previous model, the exterior design has been changed, including the color of the white paint.
