Canon has expanded its family of ultra wide-angle lenses for its EOS DSLR cameras to include the new EF-S10-18mm f/4.5-5.6 IS STM and the EF16-35mm f/4L IS USM.
EF-S10-18mm f/4.5-5.6 IS STM
The compact-sized EF-S10-18mm f/4.5-5.6 IS STM aims to appeal to casual users who are keen on landscape photography. It is 20 percent smaller and 38 percent lighter than the existing EF-S10-22mm f/3.5-4.5 USM lens and even shorter in length than the EF-S18-55mm f/3.5-5.6 IS STM kit lens, according to Canon.
The EF-S10-18mm f/4.5-5.6 IS STM also features stepper motor mechanism (STM) to deliver fast, quiet and accurate focusing when taking still images, and during focus shift in video mode without addingmore noise.
EF16-35mm f/4L IS USM
The EF16-35mm f/4L IS USM (ultrasonic mechanism), on the other hand, is the latest entry into Canon's professional L series of lenses and is the first to come with an Image Stabilizer, according to the company's press release.
Equipped with IS active, the lens offers a 4-stop light advantage for shake correction, allowing it to be used when tripods are not available, in challenging lighting situations or shooting in locations where flash photography is forbidden.
Similar to other lenses from the L series, the EF16-35mm f/4L IS USM promises high durability and toughness for reliable usage. The lens mount, switch panel, zoom ring and focusing ring have all been constructed with a dust-proof and drip-proof structure, allowing it to be used in harsh conditions. The surface of the lens elements are also coated with fluorine, which easily repels water and oil so that they can be easily wiped off with a dry cloth.
