Viltrox has released a new firmware update that restores full compatibility with the Sony A7 V for its E‑mount lenses, resolving the connection and autofocus issues reported shortly after the camera’s launch. If you experienced “lens not recognized,” unstable AF, or aperture reporting errors on the A7 V, this update is designed to bring your Viltrox lenses back to normal operation.
For context on the camera and our continuing coverage, see: Sony a7 V — Official Announcement and Sony a7 V — Hands‑On Coverage.

How to install the Viltrox firmware update
- Identify your lens and current firmware
Check your exact model (e.g., AF 24/1.8 FE, AF 35/1.8 FE) and note the current firmware via camera menu or Viltrox utility. - Download the correct files
Visit the Viltrox Download Center, select your lens, and download the latest firmware and updater (if required). - Prepare hardware
For lenses with a built‑in USB port, connect directly with a reliable cable. If your lens uses a Viltrox dock, attach the lens to the dock and connect to your computer. - Run the updater
Launch the official Viltrox updater, select the lens, and load the downloaded firmware file. - Update without interruption
Start the update and do not disconnect the lens or power until completion. Wait for the success confirmation. - Verify on the Sony A7 V
Mount the lens, power on, and test AF, aperture control, EXIF, and video. If issues persist, re‑download and repeat the process.
For Viltrox’s official instructions and troubleshooting, see the Lens Firmware Update Guide.
Should you update?
- Sony A7 V users: Yes. This update targets A7 V‑specific compatibility and AF issues and is strongly recommended.
- Other Sony bodies (A7 III/A7 IV/FX): Recommended if your lens is listed, as you may gain stability and metadata fixes.
- Professional workflows: Update, then run a quick AF/exposure test before paid shoots to confirm consistent behavior.
- If everything already works: Check your firmware version. If the changelog doesn’t apply to your lens, you can defer—but A7 V users generally benefit.
