Camera firmware updates, what is it and why it’s Important
Inside your camera is a microprocessor (small computer), that uses software stored on non-removable flash memory inside your camera. This is called firmware and is the operating system of your camera which allows you to control the features and functions, with the camera’s menus and buttons. Firmware also controls autofocus, exposure, image processing, noise reduction and other important functions within your camera. Without firmware your camera would not be able to operate.
Why check for camera firmware updates?
Updates generally contain fixes or feature enhancements. Firmware updates aren’t always necessary – some cameras never have updates.
When a new camera is assembled the manufacturer loads the firmware that was designed at that time. After the camera has been released to the public, people may find that there are bugs or problems with the way the camera operates. The manufacturer investigates these problems and produces fixes for them in the form of firmware updates. Some of these fixes can be minor, but some of them fix more serious issues such as autofocus problems, battery-draining issues, or the camera unexpectedly locking up.
Other reasons why firmware updates are released is to include new camera features such as added languages, or to have manually adjustable settings that were once solely automatic. Some updates are to support new optional accessories for your camera (e.g. wireless functions or GPS modules, etc.). I like to think of them as free upgrades to your camera.
When to check for camera firmware updates?
I recommend checking for updates on a semi-regular basis, every few months or so, and after you purchase a new camera is also a good time to check. There will likely be fewer firmware updates for older cameras but still worthwhile checking, perhaps on an annual basis. If you have never checked your camera for a firmware update then now is a good a time to do so.
Does your camera have the latest firmware?
First check what version of firmware your camera is running. This information is found within one of your camera’s menu options. Finding it is different on every camera and not always obvious. Your instruction manual will help you find where to look in the menus.
