How to Upgrade Your DSLR’s Firmware

DSLR cameras—just like many other programmable digital devices—use firmware. It is a software program preinstalled in the device that provides it with certain control, monitoring, and data usage features. And the most exciting thing is that the firmware may be and should be updated in order to make the device function better.

Often people who have a DSLR don’t examine the menu settings carefully and the firmware update option slips from their attention. Today we decided to explain you how you can update your camera firmware in less than ten minutes and make your DSLR perform more efficiently.


The firmware version in digital cameras answers for the menu design and menu options, bug fixes, and data associated with lenses. As an example, we took a Nikon D7000 DSLR and updated its firmware. Let us expound on it a bit more.

Nikon cameras usually have two types of firmware, A and B, as well as L version that contains the lens distortion data. The two former firmware types may come in one file or separately, whilst the latter firmware should be always updated after the A/B firmware update to function properly. The L firmware is updated in the same way as the A and B firmware.

Canon firmware is most often only one file and the firmware update process is pretty much the same as that of Nikon. However, we still recommend you to double-check the firmware update instructions for your camera on your camera brands’ websites.


The first thing you will need to do is to fully charge your battery or find your AC adaptor and connect the camera to the power source. If the battery is at least half low, the chances are that the camera won’t let you perform the update for safety reasons.

  1. Find out your current firmware version by going to Menu -> Setup menu -> Firmware version on Nikons and Menu -> System settings -> Firmware version on Canons.
  2. Format your memory card in the camera and connect it to a PC or laptop through a card reader.
  3. Download the firmware from Canon or Nikon’s website and unzip it.
  4. Copy the firmware—which is usually a bin file—to the root folder of the memory card. Insert the memory card with the new firmware into your camera (use the first slot if your camera has two memory card slots) and turn the camera on.
  5. Go to the Firmware update menu and perform the update following the instructions the camera will give you.
  6. After completion of the update and when you are allowed to do so, turn the camera off and remove the memory card.
  7. Turn the camera on again and check the current firmware version. Just like you did in the second item in this how-to.
  8. If everything is right, turn the camera off and wait at least five seconds. Neither disconnect it from the AC adaptor nor take out the battery during this time unless you want to damage your camera.

And it’s done! As you can see, there is nothing difficult to it at all. Enjoy the new menus, quicker functioning, and updated lens data.
