After plenty of leaks, the Canon EF 16-35mm f/4L IS USM and EF-S 10-18mm f/4.5-5.6 IS STM lenses have been officially announced. As expected, the 16-35mm f/4L IS USM lens comes in at a significantly higher price point ($1199) than the non-stabilized EF 17-40mm f/4L USM lens.
However, a nice surprise for Canon APS-C shooters is that the EF-S 10-18mm lens comes in at a very affordable $299. The 10-18mm zoom range (16-28.8mm full frame equivalent) mates nicely with Canon’s current affordable EF-S 18-55mm and 55-250mm lenses, both of which also feature the new STM focus motor.
More details below.
Canon EF 16-35mm f/4L IS USM
From Canon: The EF 16-35mm f/4L IS USM ultra wide-angle zoom lens features newly developed, high quality Canon optics that incorporate three GMo (Glass-Molded) aspheric lens elements, including a large-diameter aspheric lens, which help improve image quality by correcting aberrations. Two additional UD lens elements help reduce chromatic aberration from edge to edge throughout the entire zoom range for excellent image quality with high resolution and contrast. The lens also features enhanced fluorine lens coatings on the front and rear lens surfaces to repel dust particles and help ensure superb color balance while minimizing ghosting. The inner focusing and ring USM offer silent, fast and accurate autofocusing. Full-time manual focus adjustment is available in autofocus (AF) mode. A nine-blade circular aperture creates beautiful, soft backgrounds. A new compact four-group zoom system provides a minimum focusing distance of 0.28m/11 inches throughout the zoom range and a maximum magnification of 0.23x at the telephoto end for outstanding performance.
Canon EF-S 10-18mm f/4.5-5.6 IS STM
From Canon: The EF-S 10-18mm f/4.5-5.6 IS STM ultra wide-angle zoom lens features a compact and lightweight design with an Optical Image Stabilizer for shake correction up to four shutter speed stepsiii, enabling handheld shooting in low light. The lens’ stepping motor and newly designed focus mechanism are ideal for Canon EOS Movie Servo AF (available on EOS 70D, EOS Rebel T5i and EOS Rebel SL1 cameras) to provide smooth, quiet and continuous autofocusing during video shooting, as well as when taking photos.
The EF-S 10-18mm f/4.5-5.6 IS STM ultra-wide zoom lens features one UD lens element to help reduce chromatic aberration throughout the zoom range for excellent image quality with high resolution and contrast. It also features enhanced multi-layer lens coatings to help ensure superb color balance while minimizing ghosting and flare, while a seven-blade circular aperture creates beautiful, soft backgrounds.
Compared to the EF-S 10-22mm f/3.5-4.5 USM wide-angle lens, the EF-S 10-18mm f/4.5-5.6 IS STM ultra wide-angle zoom lens is nearly 20% smaller and 38% lighter.
