Unique among other 24-70mm f/2.8s, this lens features an internal zoom design, along with an internal focusing design, that maintains the overall length during use. This reliable and comfortable design has several benefits for photographers:
- Internal design contributes to a 16% (4.5 oz) savings in weight and is also about 0.5" shorter compared to the previous generation lens when fully extended.
- The streamlined design also contributes to improved dust and moisture resistance; with fewer moving pieces on the exterior of the lens, it offers more reliable performance in tough conditions.
- Internal design contributes to a 16% (4.5 oz) savings in weight and is also about 0.5" shorter compared to the previous generation lens when fully extended.
- The streamlined design also contributes to improved dust and moisture resistance; with fewer moving pieces on the exterior of the lens, it offers more reliable performance in tough conditions
In addition to streamlining the zoom design, version II of this lens also has an improved optical formula that sheds three elements while still improving resolution and image quality. - Revised optical design features two extra-low dispersion and three aspherical elements; these specialized elements limit various aberrations and color fringing for high sharpness and color accuracy.
- Improved optical design is also inherently more flare-resistant for stronger contrast when working in bright lighting conditions.
- Special attention has also been given to bokeh rendering, with an emphasis on producing smooth and natural transitions between in- and out-of-focus regions for a more three-dimensional look. Aspherical element manufacturing has been improved for a smoother look, and the lens also now has 11 rounded diaphragm blades for a more rounded bokeh appearance.
- Minimum focusing distance has also been significantly shortened compared to the previous generation—9.4" at the 24mm position and 1.1' at the 70mm position, with a 0.32x maximum magnification at the minimum focusing distance from the 70mm position.
Built for professional use in virtually any situation, the 24-70mm f/2.8 S II is especially durable and reliable even with its emphasis on a smaller, lighter weight design that makes it easier to use over the course of an entire day. - Lighter design weighs 1.5 lb compared to the previous generation, which weighed 1.8 lb.
- Internal zoom design maintains a consistent overall length of 5.9" — this is 0.5" shorter than the previous generation when fully extended but also is nearly 1" longer compared to the retracted size.
- Updated design also now uses smaller 77mm-diameter screw-in filters.
- Complementing the internal zoom design, advanced weather sealing also helps prevent dust and moisture ingress.
- Dedicated focus and zoom rings for direct control pair with a customizable Control Ring, which can be assigned to adjust other shooting settings, including aperture, exposure compensation, and ISO.
- Control Ring now features a configurable click; an on/off switch changes the tactile feel of the ring depending on shooting style, with the option to have a prominent click when changing settings or smooth, silent rotation to limit unwanted noise and vibration.
- Two L-Fn buttons are featured on the lens barrel—one on top, one on the left side—and can be set to configure subject tracking, AF lock, image playback, or other modes.
- Focus limiter switch can constrain the focus range to 1.1'-infinity or to the full 9.4"-infinity ranges.
- Included HB-117 Lens Hood incorporates a filter adjustment window, which enables easy adjustment of rotating filter types, such as variable ND and polarizing filters.
