The Benefits of Autofocus Tuning

Did you know that around 80% of DSLR lenses,
and almost half of all adapted mirrorless lenses
will show a noticeable sharpness improvement after calibration with FoCal?

Sharper Shots

Sharpen your images before you take the shot: with a calibrated lens, you get the performance your gear was designed to give you, and which you paid for!

Better Performance

Tuning your lenses speeds up your autofocus as well as helping you get more in-focus shots.

How Reikan FoCal Helps

1,000's of Nikon and Canon digital SLR and Nikon Mirrorless camera users trust Reikan FoCal to test and adjust their camera and lens focusing.

Using advanced image processing FoCal provides automated focus calibration and lens testing on modern digital SLR and Nikon Z series mirrorless cameras, identifying any issues and improving lens sharpness.

Just wanted to say what an amazing piece of software FoCal has made. Most of my lenses are older Nikkor such as a 35-70 F2.8 D I was having some issues with. It turns out most of my lenses needed some calibration, FoCal has done an amazing job on them.
