Q: 5. Will this work with the Canon 80D 18-135mm lens?

A: This is a beauty and lets you do things with a DSLR which were not possible in the past. I bought two from B&H!. However, be careful and be fully aware that it works with only one lens in the entire Canon lineup of lenses. That is the 18 - 135 Canon Nano USM Lens that comes bundled with the Canon 80 D and now the Canon 77 D. Please note that this lens is priced very high if you buy it as a stand alone lens, it makes sense only to be bought as a bundle. While buying the 80 D or the 77 D, please be sure that you are getting the 18 135 Nano USM Lens which works with the PZ E1! Here in India, a few smart re-seller are bundling it with cheaper and older versions of the 18 - 135.

Q: 6. Will this work with a Canon 70d?

A: I also think that is more specific to the lens type. I use it on an 80D I just bought, it is awesome but when i was shopping for it, it was clear that it is mad to work with specific lenses. In my research it didn't say anything about the type of camera, only the lens. Not a definitive answer but may offer a little clarity. B&H photo is very helpful when you call them directly. For a definitive answer, I'd call them.
