In addition to the new Canon EOS 80D DSLR camera, Canon U.S.A., Inc., is also introducing the Canon EF-S18-135mm f/3.5-5.6 IS USM Lens, a newly designed lens with a premium exterior design that will serve as the kit lens for the new Canon EOS 80D camera. This the first Canon lens equipped with Nano USM, a new type of focusing motor that combines the benefits of a ring USM (ultrasonic motor) for high-speed AF during still photo shooting and lead-screw type STM (stepping motor) for smooth and quiet movie AF, and improved AF speeds up to 4.3x (Tele) and 2.5x (Wide) faster than the previous model. The Canon EF-S18-135mm f/3.5-5.6 IS USM Lens also provides up to four stops of optical image stabilization. A new lens hood, the EW-73D, is included with the new lens.
To further enhance the ease-of-use when shootings movies with a Canon DLSR or Cinema EOS cameras, Canon is introducing the Power Zoom Adapter PZ-E1, specifically constructed to be compatible with the design of the new Canon EF-S18-135mm f/3.5-5.6 IS USM Lens. The Canon Power Zoom Adapter PZ-E1 is the world’s first detachable zoom adapter that provides silent and smooth zoom and can adjusted incrementally to 10 different levels of zoom speed3. Additionally, the PZ-E1 can be controlled remotely using the Canon Camera Connect app4.
In addition to the new lens and power zoom adapter, Canon is introducing the first Canon-branded external microphone for the EOS system, the Canon Directional Stereo Microphone DM-E1. This new accessory microphone will help improve sound quality while shooting video, allowing users to rotate the direction of the microphone up and down from 90 to 120 degrees depending on the shooting situation. The DM-E1’s durable shock mount construction helps to reduce camera operation noise and lens drive sounds and is built to withstand the rigors of a variety of shooting situations. Featuring a frequency response range of 50Hz to 16kHz, the DM-E1 comes with a wind screen to help limit peripheral sound from wind and other outside factors, allowing shooters to utilize the microphone in a broad amount of shooting situations. Featuring a built-in power supply from a single “button-type” lithium cell battery, the DM-E1 also has a power indicator lamp allowing users to easily check its battery level.
Canon’s new Nano USM technology uses a completely different form factor, but achieves focus results within the lens via the same principles of ultrasonic vibration energy, transmitted here into linear (rather than rotational) movement within the lens. This tiny new Ultrasonic motor achieves the combination of fast, near-instant response during still image shooting, with the smoothness required for good focus during video recording.

Imatest showed resolution to be even more variable than the STM lens and at no point was JPEG resolution able to meet the levels we expected from the 80D's 24-megapixel sensor. The highest overall resolution was at f/6.3 with the 24mm focal length, as shown in the graph of Imatest results.

Image quality is pretty good rather than outstanding. Centre and edge sharpness isn't great throughout the zoom range at the maximum aperture, but stopping-down by one stop sharpens things up considerably, whatever focal length you use. Chromatic aberrations aren't very well controlled, though, and there's obvious geometric distortion at the wider focal lengths and some obvious corner shading at the maximum aperture.

Power Zoom adapter review
The zoom mechanism works very well to provide a fluid and smooth movement when using it for video recording. Switching to fast is ideal if you’re using the camera remotely and want to quickly move from one zoom setting to another.
