Canon Announces Three New Lenses
In addition to the 7D Mark II, Canon also announced three new lenses this week at Photokina: EF 400mm f/4 DO IS II USM, EF 24105mm f/3.55.6 IS STM and EF-S 24mm f/2.8 STM. The first two are designed to work on both full-frame and APS-C cameras, while the 24mm f/2.8 is designed to be only used on cropped sensor cameras. The EF 400mm f/4 DO IS II USM is an update to the first model of the lens that was produced back in 2000, and this time Canon put a lot of new technology into the lens and has updated the lens design. The letters DO stand for Diffractive Optics, which not only reduce chromatic aberrations thanks to their different light dispersion path, but also allows for much smaller lens design. As a result, the EF 400mm f/4 is significantly smaller and lighter than the regular 400mm f/2.8L lens. In addition to the above benefits, the 400mm f/4 DO IS II USM now has better coatings to reduce ghosting and to improve color balance. Just like the professional L lenses, the lens has both dust and water-resistant construction and a 3 mode Image Stabilization system that offers up to four stops of vibration compensation. At $6,899 it is not a cheap lens by any means, but at the size a little bigger than a 70-200mm lens, it is surely an attractive choice for those that want to be able to hand-hold a 400mm lens.
