I didn't know Why EOS R only written Manual selection AF points using cross-key on many websites,
I searched for EOS R's Automatic selection AF point and found it.
This source was found in the Official website of Canon Canada.
http://www.canon.ca/dam/Campaigns/EOS-R/pdf/canon_eos_r_sell_sheet_CAD.pdfNumber of Focusing Points:
Maximum 143 automatically selected
Maximum 5,655 manually selectable* (When selected with cross keys)
* Available AF points may decrease when shooting with AF cropping or in movie mode, or depending on camera settings or lens attached.
......Wait, What?
143 Automatic AF points?
Seriously?
