Troubleshooting Sigma Cameras


Troubleshooting Sigma Cameras

Sigma makes a variety of cameras, including the SD15 pictured here.


You may experience problems with your Sigma camera from time to time that don't result in any error messages or other easy-to-follow clues as to the problem. Troubleshooting such problems can be a little tricky. Use these tips to give yourself a better chance to fix the problem with your Sigma camera.

  • Autofocus isn’t working. If you cannot seem to make the autofocus work properly, try moving away from the scene a little bit, as the autofocus might not work if you’re too close to the subject. It’s also possible that the camera is set to manual focus mode (M) or that the lens hasn’t been connected properly.

  • Camera doesn’t seem to power on. If the LCD screen remains blank, you may have a few different problems. First, make sure the battery is properly installed and is fully charged. Otherwise, the Sigma camera’s LCD may be in a “sleep” mode. Try pushing any button to return the camera to regular operational mode. It’s also possible the LCD has been turned off, so press the monitor button (marked with a rectangle).

  • Cannot shoot images. If your Sigma camera will not shoot new images, you can try a few different potential solutions. First, make sure the camera is done storing the image you just shot and that the flash has recharged. Depending on the type of photo you’re shooting, your Sigma camera might need a few seconds between photos. If your memory card is full, the camera will not shoot additional photos, meaning you’ll need a new memory card or you’ll need to delete some photos. If the memory card is corrupted, the camera may no longer be able to shoot additional photos. Finally, it’s possible the memory card is write-protected and locked.

  • Exposure setting icon is blinking. When this is occurring on your LCD, the exposure control setting is set outside of the allowed range. Just change the exposure value until you reach an allowable value.

  • Images won’t appear on TV. With Sigma cameras, displaying photos from the camera on your TV is an easy, automatic process. Just make sure you have the audio-video cable connected correctly; having the AV cables connected in the wrong order is the most common reason for this problem.

  • LCD is blurry. First, make sure the photos themselves are sharp by downloading them to a computer and viewing them. If the photos are sharp on the computer but blurry on the Sigma’s LCD screen, the LCD might need to be cleaned. Use a dry, soft cloth to clean the LCD. Finally, a very rare problem with Sigma cameras involves the LCD wearing out, resulting in blurry images, and it will need professional replacement.

  • Memory card isn’t working. It’s possible that the memory card is simply malfunctioning, which can be fixed by formatting the card, which erases all data from the card. It’s also possible that the SD memory card’s write protection switch is in the “lock” position, which will leave the memory card unusable.

  • Photos are blurry. The most common cause of blurry photos is from camera shake. Try using a tripod to make sure the camera remains steady as you shoot pictures.

  • Shutter is not working. Typically, this problem occurs when the camera cannot achieve an autofocus lock on the scene. You also could have an exhausted battery or an incorrectly inserted memory card if the shutter will not work.

  • Sound is unavailable in playback. This problem usually occurs when the camera’s volume is inadvertently set to zero. On most Sigma cameras, press the T button to turn up the volume or look for the volume control in the menu system.
