Try reading again... They refers to every Cinema EOS camera made (which have built in NDs and XLRs), not the GH5 (which does not). The GH5 and BMPCC4k are very capable small senor cameras so long as you have a range of accessories that come built into cinema cameras, dont need AF, and so long as you have good light. That means they do not compete with the Cinema EOS line, FS5/7 or EVA1, and its part of why they are priced differently.
