- Bulletproof Guide to Sony Camera Firmware Updates by Brian Smith
- Warning: Brian Smith’s guide is good. But, a part of step 5 “disabling security software” is very questionable, and not recommended, especially if one is still connected to the Internet, as your computer may be vulnerable during the time the security software is disabled. Do not disable security software!

- When you shoot 4K, 24fps in full frame mode on the A7 III, your video will be stretched vertically. Your video looks squeezed when compared to the Super 35mm mode or when compared to full frame HD.
- For now, you can either ignore the issue (very minimal effect on most shots) or you can stretch the X axis by 1% in your editor.
