Sony has released crucial firmware updates for four of their most popular full-frame cameras: the A7R V, A7CR, A7C II, and ZV-E1. These updates address stability issues that many photographers have been experiencing in real-world use.
The latest firmware versions fix camera restart problems during face recognition and improve movie recording reliability – these are essential updates for anyone experiencing these issues.
Having worked with Sony Alpha cameras for over 5 years, I’ve learned that firmware updates might seem minor, but they often solve the frustrating bugs that disrupt actual photoshoots. I remember once losing a critical shot because my camera restarted unexpectedly during a portrait session – exactly the type of issue these updates address.
In this guide, I’ll walk you through exactly what each camera’s firmware fixes, how to install it safely, and share real experiences from photographers who have already updated.
What These Firmware Updates Fix?
Firmware updates are essentially software patches for your camera’s internal operating system. They fix bugs, improve stability, and sometimes add new features.
These particular updates focus on three critical issues that users have been reporting across all four camera models.
Operational Stability: This refers to the camera’s ability to function normally without unexpected restarts, freezes, or errors during operation.
The main improvements include:
– Fixes for unexpected camera restarts during face recognition
– Improved time code retention in movie recordings
– Enhanced overall operational stability
– Better exposure stability in certain conditions
After spending $2,500 on my first Sony A7R III, I learned the hard way that keeping firmware updated is non-negotiable. A single stability issue can cost you shots you can never recreate.
Camera-Specific Updates and Versions In 2025
Each camera model has its own specific firmware version and improvements. Let me break down what’s available for each model based on my research and community feedback.
Sony A7R V – Version 2.02
The flagship A7R V receives firmware version 2.02, which might seem like a minor number bump, but addresses several annoying issues users have been reporting.
Key Fixes:
- System Software Stability: Resolves random restart issues that occurred during face recognition operations
- Time Code Management: Fixes time code retention problems in movie recording mode

Sony ZV-E1 – Version 1.03
The vlogging-focused ZV-E1 receives version 1.03, focusing on stability improvements crucial for content creators.
Improvements Include:
- Recording Stability: Fixes for unexpected stops during video recording
- Bug Fixes: Various minor issues affecting user experience
- Performance Optimization: Better thermal management for extended shoots
Several ZV-E1 users on YouTube reported the update resolved an annoying issue where the camera would sometimes stop recording after 30 minutes, even when not hitting the 30-minute recording limit.
How to Update Your Camera Safely?
Updating camera firmware can be nerve-wracking – you’re essentially performing brain surgery on a $2,000+ piece of equipment. But with proper preparation, it’s a straightforward 5-minute process.
Quick Summary: Backup your settings, charge your battery to 100%, download firmware from Sony’s website, format a memory card in-camera, copy the firmware file, and update through the camera menu. The entire process takes 3-5 minutes.
Step-by-Step Installation Guide
- Backup Your Settings (Optional but Recommended):
Go to Menu → Setup → Save/Load Settings → Save. Save to your memory card. This preserves all your custom settings if something goes wrong.
- Charge Your Battery Fully:
Never attempt a firmware update with less than 80% battery. I recommend 100% to be safe. A failed update due to dead battery can brick your camera.
- Download the Correct Firmware:
Visit Sony’s official support site for your region. Search for your exact camera model + “firmware.” Double-check you’re downloading the right version – firmware is model-specific.
- Format Your Memory Card:
Use a fresh or freshly formatted SD card. Format it IN THE CAMERA (not computer) to ensure proper file structure.
- Transfer the Firmware File:
Extract the downloaded ZIP file. Copy the .bin file (DO NOT rename it) to the ROOT directory of your memory card – not inside any folder.
- Install the Update:
Insert the card, turn on the camera. Go to Menu → Setup → Setup Option → Version → Software Update → Execute. The camera will restart automatically.
- Verify Installation:
After updating, check Menu → Setup → Setup Option → Version to confirm the new firmware version is installed.
⏰ Time Saver: Windows users – right-click the downloaded firmware file and select “Properties.” If you see an “Unblock” checkbox at the bottom, check it before copying to your SD card. This prevents Windows security from blocking the update.
Real User Experiences After Updates (2025)
I spent hours reading through Reddit, photography forums, and talking to local photographers about their update experiences. Here’s what the community is saying:
Positive Experiences:
- “Updated my A7C II, took about a couple of minutes. The Dynamic Active stabilization is genuinely impressive – handheld footage looks gimbal-stabilized.”
- “A7CR firmware 2.00 fixed the face recognition restarts I was experiencing during wedding shoots. Haven’t had a single restart in 3 gigs since updating.”
- “The framing stabilizer on my A7C II is subtle but effective. Keeps horizon lines steady when walking while filming.”
Issues Encountered:
- Some Windows users needed to unblock the firmware file as mentioned above
- One user reported their A7C II got stuck during update – had to remove battery and retry
- Minor confusion about which firmware file to download (multiple versions available)
⚠️ Important: If your camera gets stuck during update, DON’T turn it off. Wait 10 minutes first. If still stuck, remove battery, wait 30 seconds, reinsert, and try again. Contact Sony Support if issues persist.
