Features
1. The Image Stabilizer gives the equivalent effect of a shutter speed four stops faster*.
This function provides optimal image stabilization depending on shooting conditions (such as shooting still subjects and following shots).
2. UD lens elements for excellent imaging performance.
3. Great close-ups at 1.1 m/3.6 ft at all focal lengths.
4. A truly round aperture hole results in a nicer background blur.
* Based on [1/(focal length x 1.6)] second. Generally, it requires a shutter speed [1/focal length] second or faster to prevent camera shake (in 35mm format. With an EF-S lens, it would be [1/(focal length x Conventions used in this instruction 1.6)] second).
Exterior design improvements on the Series II Model includes a high-grade platinum ring mounted in front of the zoom ring for easier operation, and a leather tone texture coating on the body for a luxurious feel. Also environmentally-friendly, lead-free glass is used in the construction of the EF-S 55-250mm f/4-5.6 IS II.
