Sony’s A7 IV full-frame camera just got a new firmware update, version 1.10. It has a lot of fixes and new features that are helpful, but there are a few things to keep in mind.
Like when you update your computer’s operating system, you should install a camera firmware update when it’s available. These software packages usually fix bugs, add new features, and make your device work better. Some updates, like 1.10, can cause new problems if they are not installed correctly.
Sony’s own support site says that you can avoid this problem by installing this firmware version in a certain order. These are the steps.
Basically, though, you should check your A7 IV’s firmware version before installing the update to see if it’s still stuck on a version lower than 1.01. If so, you must first get update 1.05 and install it before you can get Ver. 1.10 and install it. What’s going on? Version 1.10 builds on top of Version 1.05 instead of adding to it, so it needs Version 1.05 to work.
On the other hand, cumulative updates include all of the parts of previous updates and can be installed on their own. You should also keep this difference in mind for any future firmware updates.
It’s important to know that Sony now lets you install these updates without using OS installer software on your PC. You can transfer the files instead with an SD memory card.

In other words, if you want your Sony A7 IV device to work better and have a few more features, you should install Firmware update Ver 1.10. Just make sure you look at the link for Sony support first.
