Hi, all.  Gary Friedman here, author of the book you purchased on the A7 IV.  Guess what?  YET ANOTHER firmware update has been released for that camera (version 4.0), and as always, I'm providing a free supplement for the book covering the new features.

This is the third such supplement I've had to publish, so in case you're losing track of them all, here are the download links for ALL of the supplements:

Supplement for Firmware v1.10:

Supplement for Firmware v3.01:

Supplement for Firmware v4.0:

Hope you find these useful.  As always, if you like my policy of free updates (and also like the way I explain things), then please help spread the word about our ebooks online!  Word-of-mouth from extremely satisfied customers is our only means of advertising.

Sincerely, Gary
