Reikan FoCal 2.6 Mac MR1 – Adds Full macOS High Sierra Support For Canon Cameras Posted on February 5, 2018 February 27, 2020 by Rich We’re delighted to announce FoCal 2.6 Maintenance Release 1 (MR1) for Mac is ready for release!

One of the main drives for the major software rewrite was to become compliant with future macOS updates for Apple computers that will require all apps to use 64-bit architecture. Not all changes were under the hood, however, and FoCal has some UI improvements to show more information about the connected camera and even support for dark and light themes.

Reikan Technology Ltd FoCal 2.5.0 Introduction 11 1 Introduction FoCal is a software utility designed to control a Canon or Nikon DSLR camera and automate the process of choosing the perfect AF Microadjustment/Fine Tune value for the attached lens. Getting Started With Reikan FoCal. Thank you for your recent purchase, we want to get you up and going as quickly as possible! This handy guide is designed to help you get started, covering important information you'll need to know.

FoCal 2.9 is also bringing 'faster, more reliable' communication for connected Canon cameras to Windows, something that Mac users received in a previous update. The calibration software is also speeding up their capture and analysis methods so that these tests will overlap. For a full list of all the changes in version 2.9, check out the news post on Reikan's website.

I first heard about FoCal about a year ago but put off buying it because of the price for the Pro version (which is needed if you have lenses over 400mm) and some of the reviews I read about the software being confusing or difficult to connect. Then earlier this year I saw someone mention it and was about to repeat some of the bad reviews I read before I caught myself and decided I needed to try it for myself before I bad mouth it without even knowing. I'm so glad I did, because none of the bad reviews I saw held up. It has a lot more features and tests beyond the basic autofocus microadjustments, sure, but it's not at all confusing. The software walks you through the entire process for autofocus calibration in baby steps if you want it to. I've used it with multiple cameras and many more lenses and I've never had issues. It beats the pants off of meticulously setting up and shooting those slope-style targets and then having to analyze the results yourself.

In all, over 40 Canon and Nikon cameras are supported in FoCal 2.9. Reikan FoCal Plus and FoCal Pro can be purchased through B&H Photo which comes with a standard hard target. Current owners who bought FoCal after October 1, 2017 can update for free by logging into their Reikan account and downloading the new release.

This page will show you what you need to do to run your first calibration. You should have the software installed and ready to go, but if you're not in that position head to the guides below to help you get set up.

• If you've just got your boxed copy of FoCal and are unsure what to do, have a look here for information.
• If you want more information about installation, head here for Windows or here for Mac install instructions.

Setting up for your calibration

You're going to need a few things to get going with the calibration:

Your camera and the lens you want to calibrate

• A USB cable to connect your camera to the computer - this is usually supplied with the camera.
• A sturdy tripod
• A FoCal target - either a FoCal Hard target like the one supplied in the box or available from the FoCal Store, or a target image printed on quality paper.

You'll need to attach the target to a flat, vertical wall and aim the camera at the target, so pick a height at which you can easily aim the tripod mounted camera.

The distance between the camera and the target is important for a good calibration. If the camera is too close to the target, the results of the calibration won't be as good for general shooting.

The Target Distance Tool will help you choose the right distance, but here are some examples for common lens focal lengths:

Your camera will also need to be close enough to your computer to be able to plug in the USB cable. If you're using a laptop this won't usually be a problem, but if you have a desktop then consider this when choosing a calibration location. You can use a USB extension cable but in our experience these can cause some problems with reliability and we wouldn't advise it unless you have no other choice.

Lighting

The purpose of the calibration is to make sure that the AF system of your camera and lens is working together perfectly. To be able to do this, we need the AF system to work to the best of its ability, and for this we need plenty of light on the target.

FoCal will check the lighting level before running a test and you can adjust if necessary, so pick a location to start with and you will check to make sure it's OK with FoCal before you calibrate (this is covered below).

The best setup is to have the target in a well lit room. If FoCal is warning you that the light level is too low, you can supplement the lighting on the target with a constant light source. It's best to avoid fluorescent or cheap LED lighting as these can flicker and cause problems with calibration.

Outdoors initially sounds like a good idea, but any wind can disturb the setup and clouds can change the light level during the test and cause calibration problems, so we wouldn't recommend this.

Camera and Lens

The camera should be on a sturdy tripod, aimed at the target at the appropriate distance away. If you usually use a battery grip, it should be removed for calibration as it can increase vibration and reduce the quality of the calibration results.

Look through the viewfinder and approximately line the centre focus point with the centre circle of the target. It doesn't have to be absolutely perfect - if you're too away from the middle then FoCal will warn you when you check the Target Setup (explained below).

The USB cable should be connected to the camera and the computer.

For the very best results, it's a good idea to cover the viewfinder of the camera. The camera is usually used with a human head stopping light from entering the viewfinder, but this isn't the case when running with FoCal and stray light can upset the metering system and cause calibration problems.

Some cameras have a built in switch to cover the eyepiece, while others may have an attachment on the strap that can cover the eyepiece. If you have neither, a piece of dark paper hung over the back of the camera will suffice.

Camera and Lens Settings

FoCal takes control of the camera and can change most settings, but there are a few final things worth checking before starting:

• Canon: Switch the camera mode dial to Av and the shooting mode to ONE SHOT.
• Nikon: Switch the camera mode dial to A and the shooting mode to AF-S.
• Ensure Image Stabilisation is disabled if the lens supports it
• Ensure the focus limiter is not enabled if your lens supports it

Recap

You should be ready to go now. Have a quick look at the checklist below just to make sure:

• Camera is on a sturdy tripod with no battery grip attached
• USB cable is connected between the camera and the computer
• The eyepiece of the camera is covered
• Target is mounted on a flat, vertical wall the correct distance from the camera.

Fire up FoCal!

We'll show this on Mac, but the process is the same on Windows. This is also with FoCal Pro, but all the options described are available in FoCal Plus as well.

With all the equipment in place, you can start the FoCal software (see the bottom of the Windows or Mac page if you're not sure how to start the application).

Make sure the camera is turned on and hit the Connect button - you should see some details about the camera displayed on the screen:

The first step is to verify that FoCal is happy with the setup for the test. To do this, you'll use the Target Setup Tool. Click the Tools option on the window, and then the Target Setup button.

This will open the Target Setup utility.

Hit the Start button to begin the check.

The Target Setup tool will take a photo and analyse to determine if the setup is suitable for calibration. The results will be shown in the panel on the right, and a live video image will be shown in the main window to help with any position adjustments that might be needed.

Any issues are highlighted with a or . Click on any entry to see more information.

Any entries marked with a are highlighting things that FoCal cannot check, so just have a quick glance and make sure the listed item is set as it should be in the details.

If there are any or entries you should adjust your set up and hit the Check button to retest.

When everything is set up correctly (there are no or entries), you can hit the Stop button and close the Target Setup window, confident that everything is set up perfectly for your first calibration.

Let's Get Calibrating!

Now we've checked everything is setup correctly, calibration is just a matter of starting the Automatic Focus Calibration.

Reikan Focal 2 For Macbook Air

From the main window, choose Calibration and hit the Automatic Focus Calibration button.

The Calibration window will open, ready to go.

As we've already checked the setup, you can ignore the Target Setup button and head straight down and hit the Start button.

If you've got a Hands Free Mode camera, you can sit back and watch the calibration happen. If your camera is a User Assisted Mode camera, you'll get occasional prompts to change the calibration value on the camera, like this one:

Change the value on the camera and hit OK on the computer to continue. (When you're more familiar with FoCal, have a look at Voice Prompts and Camera Hotkey in the manual for a quick and easy way to make these adjustments at the camera).

Autofocus. Fixed.

The test will run through to the end, and will show you before and after shots as well as graphical information about the results which you can dig into if you're interested.

The camera will now be adjusted to work as well as possible with this lens, so you can close FoCal, disconnect the camera and get out shooting sharper photos!
