You can download the Sony a7R IV manual in PDF format here.
However, I would actually recommend that you visit the Sony a7R IV Online Help Guide instead of downloading the manual.
The online help guide covers all of the features in much more detail and is also a lot easier to navigate than the PDF instruction manual.
David Busch’s Sony a7R IV Guide
If you would prefer a nicely formatted book written by one of the most popular camera guide book authors then I’d recommend taking a look at this one from David Busch. It’s available on Amazon.
