Autofocus checks and tuning in your pocket, on iPhone, iPad and Android.
FoCal Mobile Pro is free with FoCal Pro (Desktop) while support is active, or as an in-app subscription.
Free to download. See the app store for the subscription price, the technical specifications for the phones and tablets it runs on, and Cameras for the cameras it works with.
These work in the free app.
Connect your phone or tablet to your camera with a USB cable, and FoCal takes control of the camera.
Lightning iPhones need an Apple Lightning to USB 3 Camera Adapter, and Micro-USB devices a USB-OTG adapter. USB-C devices connect straight to the camera.
FoCal checks the camera’s alignment, the camera and lens settings, the light level, the battery and more, and shows anything you need to change before you test.
Once you’re set up, it takes one tap, and about two minutes later you’ll know whether you’re getting the best from your camera and lens.
The results come as easy-to-read scores, and you can compare the captured images to see the improvement you could get.
Free with a FoCal Pro (desktop) licence in its support period, or an in-app purchase.
FoCal measures how your camera and lens focus, then tunes the autofocus to get the best from them.
It takes a few minutes, and the improvement can be dramatic.
Look into autofocus consistency, astigmatism from lens misalignment or aberrations, image motion from movement in the lens, and more.
FoCal Comparison Data shows how your kit compares with the real-world results FoCal users have shared over more than ten years.
Look back through your earlier results, with the full details of each test, to see how things have changed.
You can also export results to FoCal Pro on your computer for a more detailed look.
Set your camera’s clock from the front screen of FoCal Mobile with one tap. Handy before an event where you’re shooting with more than one camera, so the photos sort into the right order.
Free from the App Store and Google Play.
FoCal Mobile Pro is free when you sign in with a FoCal Pro (Desktop) licence while support is active. Or turn on the Pro features with a 12-month in-app subscription: see the app store for the current price.
