How to update Sigma E-Mount lenses
How Do I Update My Sigma Lens Firmware?
Your Sigma lens firmware can be updated in one of two ways: using the Sigma USB Dock or the Sigma Optimization Pro software. We’ll cover both methods below.
Sigma USB Dock
The Sigma USB Dock is a convenient way to update your lens firmware without having to connect your camera to a computer. Just attach the dock to your lens and plug it into a power source, then follow the instructions on the screen. The process is simple and only takes a few minutes.
Sigma Optimization Pro Software
If you don’t have a Sigma USB Dock, you can still update your firmware using the Sigma Optimization Pro software. First, download and install the software on your computer.
Then connect your camera to the computer using a USB cable and launch the software. Follow the prompts on-screen to update your firmware.
Are Sigma Docks Necessary?
If you own a Sigma fp camera, then the short answer is yes, the Sigma dock is necessary. The dock allows you to update the firmware on your camera as well as customize various functions.
The long answer is that it depends on what you want to use your Sigma fp for.
If you plan on using it primarily as a stills camera and don’t care about video features or 4K output, then you can probably get by without the dock. However, if you want to take advantage of all the features that the Sigma fp has to offer (including 4K video), then the dock is going to be necessary.
How Do You Calibrate a Sigma Lens Without a Dock?
There are a few ways to calibrate a Sigma lens without a dock.

The second is to use the Sigma Optimization Pro software, which can be used to adjust the focus of your lens without a dock.
Finally, you can send your lens in to Sigma for calibration.
What Does the Sigma Lens Dock Do?
The Sigma lens dock is a tool that allows you to connect your Sigma lenses to your computer for firmware updates and other adjustments. By connecting your lens to the dock, you can ensure that your lens is always up-to-date with the latest firmware and software from Sigma. Additionally, the dock allows you to make fine adjustments to the focus of your lens, as well as calibrate the autofocus system.
