Canon hat zusammen mit der 80D ein neues EF-S 18-135 vorgestellt, das mit "Nano-USM" die Vorteile von Ring-USM und STM-Technik verschmelzen soll.
Dpreview ist sehr angetan vom ersten Kontakt mit diesem Objektiv:
Alongside the EOS 80D, Canon has announced a new version of its 18-135mm F3.5-5.6 lens. The EF-S 18-135mm F3.5-5.6 IS USM makes use of a new type of focus motor that Canon is branding 'Nano USM.' The company declined to give any further detail about the technology behind the actuator but said that it's able to offer the speed of a ring-type USM motor but is as quiet and smooth as the existing STM (stepper motor) designs.
Canon says the latest version will be 2.5x faster to focus than the existing STM version at the wide-angle end of the range and 4.3x faster at the long end of the zoom. We were very impressed in our own informal tests: the lens is able to 'snap' into focus almost instantaneously, even from extreme defocus. The Nano USM design is likely to be used on other lenses in future but can only be applied on lenses with single, light focus elements.
The lens' stabilization is rated a 4 stops by CIPA standards.
