Why FoCal

Sharp today. Still sharp next year.

Cameras and lenses get knocked, drift and wear, and it usually happens gradually. FoCal finds it, fixes what can be fixed, and keeps watch.

1The problem

You are the first person to put your lens on your camera.

The factory set up your camera and each of your lenses separately. Nobody has tuned them together, and small differences between the two add up: a shot that should be crisp comes back a little soft.

On a DSLR, autofocus is measured with a separate sensor, not the one that takes the picture, so this matters most. Mirrorless cameras focus with the image sensor itself, and those with an adjustment still need calibrating: on Nikon Z cameras, 1 in 6 native lenses is noticeably out, and 46% of F-mount lenses on the FTZ adapter. Any lens on an adapter, such as a Canon EF lens on a Z camera, adds another joint to the light path. Read how it goes wrong in the illustrated guides to DSLR and mirrorless autofocus.

2The fix

FoCal calibrates it for you, automatically.

Set up the target, connect the camera and press Start. FoCal takes control of the camera, takes the shots, measures each one and works out the autofocus adjustment that gives the sharpest result. You see the before and after side by side.

  • Target Setup checks position, distance, light and settings before you start
  • Fully Auto calibration on cameras with AF Microadjustment or AF Fine-Tune
  • Calibration Check for a quick look between Kit Health Checks

3Stay sharp

Calibration gets you sharp. A Kit Health Check keeps you there.

Every few months, calibrate and then run FoCal’s other tests while you’re set up. Do it monthly and FoCal can spot changes sooner. FoCal keeps every result and shows how each camera and lens is holding up.

Kit Status and Maintenance Watch show what needs attention, and the Analysis trends pick up gradual decline or sudden changes in how your kit performs.

4The proof

Built on over a million calibrations.

FoCal users have uploaded over a million calibration results to FoCal IQ. FoCal uses them to show how your camera and lens compare with other users of the same kit, so you can see whether a result is normal for that kit.

  • The Compare tab: your results against other users of the same camera and lens
  • FoCal IQ statistics for each camera
  • Used by FoCal Test Centres and calibration businesses
FoCal 6 Compare tab: a calibration result scored against other FoCal users of the same camera and lens. Maximum quality 93 and image motion 83 are better than most, but consistency of focus 36 and astigmatism 29 are not as good as most other users’.

From FoCal users

“By far the best.”

“I shoot a lot of documentary photography and focus is essential. I often need to capture a moment, a few seconds, that won’t come back. There is only one chance to get the shot. That is why I am using Reikan FoCal, to make sure that my lenses are as focused as possible. It makes me feel more comfortable and safe.”

Staffan ESweden

“I have tried all calibration techniques from all of the manufacturers I know of and by far the best is Reikan FoCal. I have been with them from the beginning and will stay with them in the foreseeable future. I cannot stress how easy and precise the adjustments are to use.”

Dave TUnited States

“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.”
