Data Points

Compare your Results

Since 2014, FoCal users have been uploading real-world performance data about cameras and lenses.

We carefully process this information to build detailed, real-world profiles of cameras and lenses, and then feed it back automatically through FoCal Pro and FoCal Mobile Pro so you can see how your kit really performs.

  • AF tuning adjustments required for best image quality
  • Autofocus consistency and accuracy information
  • Lens sharpness profiles
  • Sensor dust information
