Reikan FoCal: Canon EOS RP Details

FoCal Support for the Canon EOS RP

Supported Features
Automatic Focus Calibration

Focus Calibration is unavailable for this camera

This camera does not support any form of focus adjustment.


Calibration check

Calibration Check is available for this camera.

Calibration Check is a one-click tool for checking the current state of your Canon EOS RP and lens operation. In a minute or so, it will give you a result showing whether your kit is working optimally or could benefit from tuning.

Note that although you can check the autofocus operation on the Canon EOS RP, there is no facility for adjustment of the autofocus system without returning to a service centre.

Calibration Check (AF System Check) is completely free in FoCal Mobile!


MultiTest

MultiTest is available for this camera.

MultiTest gives you a two-dimensional view of your lens performance. See how your lens performs at different focus positions across the aperture range, revealing any focus shift as the aperture changes, showing the very sharpest aperture, and understanding just how much benefit calibration and manual-focusing will be for you.


Stabilisation Test

Stabilisation Test is available for this camera.

How does your stabilisation system really perform? With the Stabilisation Test in FoCal, you can investigate the benefit of your camera and/or lens stabilisation system. See the quality improvement as the shutter speed slows, and investigate whether stabilisation when tripod-mounted can actually degrade the quality.


Focus Consistency

Focus Consistency is available for this camera.

With the Focus Consistency tool, you can investigate how repeatable your Canon EOS RP autofocus system is. Choose to defocus between shots in one or both directions, and compare viewfinder (phase-detect) and Live View focusing.


Aperture Sharpness

Aperture Sharpness is available for this camera.

What happens to your image sharpness as you change aperture on your lens? With the Aperture Sharpness tool in FoCal, you can find out!


Dust Analysis

Dust Analysis is available for this camera.

Take a good look at your Canon EOS RP sensor with the Dust Analysis tool. Quantify the dust spots - see how many there are and how much of an impact they will really have on your sensor before you decide to embark on a costly and potentially risky clean.


Snapshots

The Snapshots feature is unavailable for this camera

This feature is not yet available for this camera.

Using FoCal with your Canon EOS RP

Connecting to your computer or mobile device

FoCal can take control of this camera via USB in tethered mode.

You can use the camera's built-in WiFi to connect to FoCal wirelessly.

You will require a USB cable with a USB-C connector to connect to your Canon EOS RP.
Environment Setup

Choose a location with a solid floor

Ground floor locations are less likely to vibrate when people move, trucks drive past outside the building etc. The quality of your test results will be affected if there is vibration to the camera/lens during the test.

Attach the target firmly to a vertical wall at approximately the height of the camera lens

If you print the target yourself, make sure it is flat and cannot blow around during testing. We recommend using a FoCal Hard Target (available from the Reikan FoCal Store) as these are the targets we use for all our development and testing.

Ensure the target is well lit with a stable light source

We don’t recommend the use of fluorescent or LED lighting as they can flicker – you won’t be able to see this with your eye, but the camera can be affected and the results may not be as accurate as possible. Also avoid changeable outdoor lighting - e.g. clouds moving across the sky. FoCal can compensate for small light level changes, but large changes can cause problems during testing.

Attach the camera or lens to a solid, sturdy tripod

If the option is available for your tripod, you can hang something heavy from the hook at the base of the centre column to further stabilise the camera lens during testing.

For large lenses, use the supplied tripod collar and attach the lens to the tripod (not the camera) - this will not only reduce strain on the camera mount, but also make the whole camera/lens system more stable.

Position the camera the appropriate distance from the target

The Target Distance Tool in FoCal will guide you. You can use this either with or without the camera connected to FoCal. More information is available at help.reikanfocal.com/targetdistance.

Connect the camera to the computer

You will require a USB cable with a USB-C connector to connect to your Canon EOS RP.

Use the USB cable supplied with your camera or a high-quality alternative, and avoid extension cables. Low quality USB cables can cause considerable unreliability during testing and it's usually the first thing we suggest changing if you get unreliable operation of FoCal!

Camera Setup

Check the camera battery is at least half (>50%) charged

Low batteries can cause the tests to run incorrectly or to fail. FoCal can catch and properly identify most issues, but if a battery is low or exhausted the camera may behave unexpectedly and you may see strange behavior.

Remove any battery grip from the camera

Battery grips can cause considerable extra vibration when mounted on a tripod - remove them before you calibrate.

Aim the centre focus point of the camera approximately at the centre of the FoCal Target

You don't have to be too precise - positioning will be confirmed during Target Setup.

Camera Network (WiFi/Ethernet) Setup
Further general information on Network connection - specifically related to both Hotspot ('Easy') and Infrastructure modes - is available on the Camera Network help pages.

Important: You must ensure the WiFi option for Canon is enabled in the software settings, otherwise the camera will not be detected by FoCal.

In order to enable WiFi on the Canon EOS RP:

Go to the Tools menu , page 4 and choose Communication settings.

Select Built-in wireless settings.

Ensure that Wi-Fi/NFC is set to Enable.

Choose Wi-Fi function

and from the next screen select Remote control (EOS Utility).

Easy Setup (Camera Access Point mode)

Select Easy Connection in order to configure the camera as an access point which your computer can connect to:

The camera will display connection information - the SSID (network name) and the Encryption key (password). Open your computer WiFi settings and connect to the camera network.

When the computer is connected, hit OK on the following screen.

With the following screen shown on the camera, start FoCal, go to the Camera page and you should see the camera shown. Hit Connect in FoCal, and the following screen will be shown:

You must hit OK on the camera screen for FoCal to connect.

You will see the following screen for a short time, and then the camera screen will go black as FoCal takes control.

Infrastructure Mode

Advanced: You can also configure Canon cameras to use Infrastructure mode - this is where the camera connects to your home or office WiFi.

On the Connection method page, choose Select a network, then select OK.

After a short time, the camera will show the available WiFi networks. Scroll down to choose the appropriate network, then hit OK.

You will need to enter the WiFi network password. For most home networks, you should choose Enter 8-63 ASCII characters, then OK and enter the password for your network on the camera.

After you OK the password, the camera will show Busy… please wait. while it connects to the network.

On successful connection, you will see the IP address set page. In most circumstances, you should choose Auto setting

Finally, the camera will show Start pairing devices. Click OK, and within a few seconds the caemra should be detected by FoCal.

Camera Settings

Switch to Photo mode

The Canon EOS RP can operate in both Photo and Video mode. If there is a selector switch, ensure that it is switched to Photo mode.

Disable WiFi

The WiFi feature on the Canon EOS RP can interfere with communications with FoCal over USB, so please ensure that WiFi is disabled.

Remove any mode limits

Some cameras allow you to limit available options for various settings. If this is possible on your camera, please ensure that the following are allowed options:

  • AE Mode: Aperture Priority and Manual
  • Metering Mode: Spot Metering, Matrix/Evaluative Metering
  • Aperture: All apertures
  • Shutter Speed: All shutter speeds
  • ISO: All ISO values

Switch to Aperture Priority Mode

Most tests in FoCal use Aperture Priority mode, so it's a good idea to switch to this mode when you start.

If a tool in FoCal requires a different mode, you will be asked to change.

Select non-continuous Autofocus mode

Ensure the autofocus mode of your Canon EOS RP is set to One Shot.

To check, when you half-press the shutter button, the camera should lock focus (with a beep if this is enabled), and then stop focusing.

Select single focus point mode

You should not use any automatic focus point selection modes. When you look through the viewfinder and activate autofocus (half-press the shutter button or use the AF-ON button), you should see only a single, non-moving AF point selected.

Choose the Centre focus point

Most FoCal tests require use of just the centre focus point, so set that single point (from the step above) to the centre.

Ensure Focus Limiter is disabled on lens (if applicable)

FoCal may use the whole of the lens focus range during testing. You may encounter errors if the range of focus is limited on the lens, so make sure the limiter is set to OFF or the minimum-to-maximum range (note this option is not present on all lenses - it's usually available on longer telephoto lenses or macro lenses).

Ensure any image stabilisation is disabled on lens and/or in-camera (if applicable)

You should disable any image-stabilisation option on your lens, as it can reduce the quality of the results.
