Q: 1. Just to be sure: work properly with Canon 5d Mk iv with Canon EF 70-300L IS USM? With autofocus on? IS on??

A: All electronics carry over but you will not get autofocus for most of the focal length, as you will lose 2 stops of light when using the converter. You must have an effective aperture of f/8 to get autofocus with a converter.

Q: 2. I have a D850,when using the 200-500 mm lens,will this teleconverter work?

A: Yes, it would be possible to connect the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F onto the Nikon AF-S NIKKOR 200-500mm f/5.6E ED VR Lens. However, do note that this lens/teleconverter combination would become the equivalent of a 400-1000mm f/11 lens, and would not autofocus when connected to the teleconverter.

Q: 8. Will this work with Tamron 18-400 mm lens on Canon 7D body?

Q: 9. I received this today. In the instructions, under "Important notes when using" is the statement "please turn off the IS to prevent malfunctions." What kind of malfunctions can occur? Is it really necessary to turn IS off?? If that's the case, too bad that's not clear in the information provided.

A: The instructions mention exactly, " Because IS (Image Stabilization) can be the cause of poor functionality, you should set it to OFF.". Using the IS function may cause the AF to hunt as opposed to having it turned off allowing it to lock onto a subject more easily.

Q: 10. Will this work with a Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens and Nikon D700 camera? What are the shortcomings?

A: Yes, the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F would be compatible for use with the Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens on the Nikon D700 DSLR camera. Do note that as the Nikon D700 DSLR camera requires an equivalent maximum aperture of f/5.6 or brighter to maintain autofocus, and the Nikon AF-S NIKKOR 300mm f/4E PF ED VR Lens would be the equivalent of a 600mm f/8 lens when connected to the Kenko TELEPLUS HD pro 2x DGX Teleconverter for Nikon F, you would not be able to autofocus with this setup. You would have to focus manually. That being said, automatic exposure, automatic metering, and Vibration Reduction capabilities should still be available.
