Free · In‑App Purchases
Now with support for the Nikon Z50ii and Z5ii - analyse and tune from the palm of your hand!
FoCal Mobile brings Reikan FoCal's DSLR camera calibration and analysis tools to your mobile device!
Connect your camera to your device* and FoCal takes control to analyse the performance of your autofocus system and tune it for better shots.
The free FoCal Mobile app features:
- Automatic control of all Canon and Nikon DSLRs and Mirrorless cameras which support AF tuning (AF Microadjustment/AF Fine Tune)
- Automatic verification of test setup, including camera position, lighting, camera and lens settings and more
- One-tap testing of autofocus system performance, with scores and crops to review
- Camera time synchronisation
With a FoCal Pro subscription or FoCal Pro (Desktop) license (within support), you can add:
- Calibration of your lenses, tuning your autofocus for the best performance possible. Get the very best from your camera and lenses.
- Check your autofocus with cameras that have already been calibrated.
- FoCal Comparison Database: compare the performance of your kit with 1,000s of other users to find out how it compares to *real-world* use, NOT artificial lab tests!
- Review historical data, recall tests and calibrations you've run to find out how your equipment is holding up.
- Export data to FoCal Pro Desktop for more detailed analysis, charting, reports and more.
- One-tap Time Sync - synchronise your camera time with one tap right from the first screen of FoCal.
- Calibrate and analyse lenses with focal lengths over 400mm.
* Connection is via USB or the Reikan Wireless Camera Control Module.
- For iPhone and iPad with lightning connectors, you will require a Lightning to USB Adapter in order to connect a camera - further details are provided in the app help, but a standard Lightning to USB adapter will work in most cases.
- For iPad with USB-C, you can directly connect to the camera with just an appropriate cable.
FoCal requires the use of a FoCal Target, which you can download and print using links from within the app, or purchase from the FoCal store.
You will need a FoCal account, which can be created for free from within the app. With a FoCal Pro (Desktop) license which is within the support period, you will have automatic access to all Mobile Pro features.
