The PZ-E1 Power Zoom Adapter is compatible with the Canon EF-S 18-135mm f/3.5-5.6 IS USM lens, only!

I don't think they are out yet anyway. It is designed for video so I have no interest in one. Maybe one of the other forum people can enlighten us more.

If you look at the picture it looks like the PZ-E1 has to make contact with the lens to communicate with it. We have no idea about Canon's plans, but I would guess that most proffessional lenses going forward that might be useful for video would be compatible.

I disagree, the device appears to be targeted at the amateur film maker, not the professional. I would not expect any lenses other than the current STM zoom lenses to be upgraded for compatibility.

I will admit it does look pretty hokey with it connecting (by friction!) to the existing zoom ring and all. But does an amateur really need a focus puller?

It is not a focus puller, all the Dual-Pixal AF cameras and STM lenses already do that.

It is an electro-mechanical Zoom Puller. And yes in my opinion it is intended for amateur videographers.

One problem with making such judgements is that these days it's about as hard to place videographers on the pro/wannabe/amateur/duffer spectrum as it is to place photographers.

I agree with Mr Martin.

"... in my opinion it is intended for amateur videographers."

That is about the focus motor in the lens not the Canon PZ-E1. The Canon PZ-E1 attaches to the lens to allow electro-mechanical zoom of the lens.

The new nano-USM focus motor appears to be a refinement of the existing STM focus motor, which itself was a refinement of the original micro-USM focus motor.

A micro USM (Ultrasonic Motor) provides fast, silent AF and full-time manual focusing.

STM lenses are named after the Stepping Motor, which lets the lenses focus smoothly and quietly when capturing video.

Canon L lenses use ring type USM focus motors which are required to move the heavier lens elements smoothly and quickly.

I know, but the article gives a list of bodies that will allow "smooth video focus" which I assume will be required for the PZ-E1.

No those bodies will give smooth video focus with either STM lenses, or the new nano-USM lens, NO PZ-E1 required. The PZ-E1 is for ZOOM not for focus.

We are talking past each other here.

The whole point of this is to turn your camera into a camcorder. Currently, when you zoom the lens it can go out of focus since the focus point might change as you zoom.

If all the PZ-E1 did was allow you to automagically twist the zoom ring, it wouldn't very useful since the camera would go out of focus, or the camera might hunt. I believe the PZ-E1 is tightly coupled to the zoom and focus so that you can zoom and keep things in focus while you are shooting a movie like a camcorder. It acts, as they call it in the movies, as a focus puller, too.

As I said, if you look at the pictures of the PZ-E1, there is an electrical connection between the lens and the unit to allow for tight coupling of zoom and focus.

No with the Dual-Pixal AF cameras no special attachement is required for it to maintain focus during zoom. And slow focus pulling from one subject to another is done automatically by the camera. With the 7D Mk II you can set the speed of the focus pull in the camera. I'm assuming that is probably true with the 80D also. The PZ-E1 is not required for this to occur.
