Three new lenses for Canon EOS cameras

With the EOS 7D Mark II comes three new Canon lenses:

EF 400mm f/4 DO IS II USM
EF 24-105mm f/3.5-5.6 IS STM
EF-S 24mm f/2.8 STM

With over 100 million EF lenses produced since the EOS system was introduced, Canon has added three new lenses to the already extensive line-up.

EF 400mm f/4 DO IS II USM

EF 400mm f4 DO IS II USM

Super compact and lightweight the EF 400mm f/4 DO IS II USM is roughly half the weight of the EF 400mm f/2.8L IS II USM lens, itself a game changer for lightweight 400mm lenses. A newly created dual-layered DO element is placed optimally in the optical path to reduce the flare around backlit subjects that characterised the previous EF 400mm f/4 DO IS USM lens.

Other lens technologies such as SWC (sub wavelength structure) lens coating and UD glass elements help to reduce internal flare. The nine-bladed aperture should create smooth natural looking bokeh. Similar to the other long telephoto lenses the EF 400mm f/4 DO IS II USM includes e-mode IS and power focus modes for smooth focus pulls – ideal for video.

EF 24-105mm f/3.5-5.6 IS STM

EF 24-105mm f3.5-5.6 IS STM

STM zoom lens technology comes to full-frame EOS cameras. STM motors include a lead screw-type stepping motor (STM) that provides virtually silent AF while shooting video. The 24-105mm is one of the most versatile focal range options in the EF lineup as it can be used as a wide-angle lens while out on the town as well as a portrait-length zoom when trying to get closer to your subjects. The Image Stabilizer is good for 4-stops of stabilisation and two aspheric lenses plus a UD lens contribute to the high quality results.

The lens’ lightweight inner focusing system, high-speed CPU, and improved AF algorithm enables high-speed AF. In addition, the seven bladed circular aperture combined with the optimized lens placement and coatings delivers beautiful, soft bokeh, and exceptional color balance, while helping to minimize ghosting and flare. The new EF 24-105mm f/3.5-5.6 IS STM lens provides a lighter and more affordable option with STM focus capabilities to Canon’s popular EF 24-105mm f/4L IS USM lens.

EF-S 24mm f/2.8 STM

EF-S 24mm f2.8 STM

The EF-S 24mm f/2.8 STM lens is the slimmest and lightest Canon EF-S lens ever produced. This compact, lightweight wide-angle “pancake” style lens features STM technology and was developed for photographers and videographers who are aiming to capture bright, clear images with beautiful softly blurred backgrounds at a fixed focal length. The EF-S 24mm f/2.8 STM lens features an aspheric lens element and the optimized lens arrangement and coating helps to minimize ghosting and flare while delivering excellent image quality. The seven bladed aperture delivers beautiful, soft backgrounds, while the Electro-Magnetic Drive aperture mechanism uses a micro-stepping driver control for quieter operation, especially useful when shooting video.
