question
Is it parfocal?
I just received mine & my previous answer stands. It goes soft around 30mm if I have a tight focus at 18mm & zoom. Definitely not parfocal, but definitely a beautiful lens.

question
Will this work on a 1dx mark ii for video?
This lens is meant to cover Super35 which is a 1.6x crop of full-frame. The 1DX Mark II's 4K is a 1.4x crop. Therefore this lens cannot cover it. If you were to mount it on the camera, 35mm will probably be fine but zooming out the 18mm, you would definitely get vignetting. We suggest using full-frame lenses for the 1DX Mark II 4K recording.

Will this lens work on the gh5 and also how do I need calculate the crop factor ?
The Sigma 18-35mm T2 High-Speed Zoom Lens (Canon EF) is compatible with the Panasonic Lumix GH5 Mirrorless Camera when using an EF to Micro Four Third adapter like the Metabones T Speed Booster Ultra 0.71x Adapter for Canon Full-Frame EF-Mount Lens to Micro Four Thirds-Mount Camera. This will reduce the 2x crop factor of the Micro Four Thirds sensor to a 1.29 crop factor. See the link below:

What is the difference between this lens and the sigma 18-35 that is much cheaper?
This cinema lens is manual focus only, has gears, greater throw, accurate markings and more robust housing made with finer tolerances. This are specifications that come into play on higher level video productions particularly ones that are working day to day with a crew. For one man band personal video it could be overkill.
