Telephoto EF 100-400mm f / 4.5-5.6L IS USM lens with a focal range of 100-400mm, a slippery f / 4.5-5.6 USM ultrasonic motor
EF 100 400mm f / 5.6L IS II USM 4.5 - Canon
Particularly suitable for sports photography and wildlife, this new model incorporates a series of innovations designed to optimize image quality and enhance the user experience. Its versatility and compactness, will make a real reference.
In order to meet user experience feedback from the previous model, the new 100-400mm has been optimized in several ways. This is particularly the case of zooming, which is now done by rotating a ring, common to all EF zoom lenses from Canon, when she was done with a pump device on the previous version.
Designed for use even in harsh conditions, this lens benefits from the robust and reliable construction unique to Canon lenses L. Series Its robust design to dust and moisture meets the demands of discerning photographers. This increased resistance also relates to the lens surface front and rear, protected by treatment with fluorine, reducing the adhesion of dust and staining.
Canon EF 100-400mm has the f / 4.5-5.6 L IS II USM, the second version of its telephoto zoom x4 dating back to 1998 and whose optical performance was almost unanimously considered inadequate today.
If she keeps 100-400mm zoom range, the slippery f / 4.5-5.6 USM ultrasonic motors and this new version has been completely revised and thus has many improvements. It benefits as well:
In a new approach based on building 21 lenses combined into 16 groups. The lens construction combines lenses fluorite and Ultra-low Dispersion glass (Super UD). Moreover, this EF 100-400 / 4.5-5.6 L IS II USM opens new anti-reflective coating: AUC (Air Sphere Coating). The application of nanoparticles to the lens surface creates an index layer of ultra-low refractive reducing the occurrence of flare and ghosting.
The diaphragm is made up of nine slices.
The distance of focus was particularly low: it is now 98cm at all focal lengths against 180 for the previous version!
On a new optical stabilization system, Canon claiming a 4-speed gain (against 1.5 for the first version of the 100-400!). Stabilization has three modes: standard, spun and during the exhibition only.
On the new zoom system. While the previous version was known for its unique system of zooming pump, this second version adopts a more conventional mechanism ring he just turn. Another adjustment ring, in front of the zoming ring to adjust the rotation of firmness (of "smooth" to "tight") and lock the zoom race over a fixed focal length when framing must remain constant.Specifications:
