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

You can quickly see in all results tables metrics that are worth investigation, or those where your gear outpeforms the norm.
Typical Comparison
