Canon EOS 80D

EF mountDSLRAPS-C

Can FoCal calibrate my EOS 80D?

Yes: FoCal calibrates the EOS 80D automatically.

Fully Auto calibration finds the best AF Microadjustment value for each lens and sets it on the camera by itself, with separate wide and telephoto values for zoom lenses.

And FoCal can check the rest of your kit.

Supported in FoCal 2.2 and later (File Mode from FoCal 2.1), over Mini-USB or Wi-Fi. Tests: Calibration Check, AF Consistency, Aperture Sharpness, MultiTest, Stabilisation Test and Dust Analysis.

78.5%

Tuning an EOS 80D would improve almost 8 out of 10 lenses.

And 52.8% would improve significantly. From calibration results FoCal users have shared with FoCal IQ.

Bought it second-hand?

You don’t know how a used EOS 80D has been treated. Cameras and lenses get knocked, drift and wear, usually gradually. FoCal shows you where yours stands.

  1. Calibrate it with your lenses

    Any AF Microadjustment values already on the camera were set by someone else, for their lenses. FoCal finds the right value for each of yours.

  2. See how it performs

    AF Consistency shows how repeatable the autofocus is, and Aperture Sharpness how sharp each lens is across its apertures.

  3. Look at the sensor

    Dust Analysis counts the dust spots and shows how much they matter, before you pay for a clean.

  4. Then keep an eye on it

    With FoCal Pro, a regular Kit Health Check tracks every result, so you’ll see if anything changes.

About the Kit Health Check

What you can do

Seven tests for the EOS 80D

Focus Calibration

Finds the best AF Microadjustment value for each lens and sets it on the EOS 80D by itself: a full calibration is one click.

Available

Calibration Check

A one-click check of your EOS 80D and lens. In a minute or so it shows whether your kit is working as it should.

Available

AF Consistency

How repeatable is the EOS 80D’s autofocus? Defocus between shots in one or both directions and see.

Available

Aperture Sharpness

What happens to sharpness as you change aperture, and which aperture is the sharpest.

Available

MultiTest

A two-dimensional view of the lens: focus position across the aperture range, showing any focus shift.

Available

Stabilisation Test

How much does stabilisation really help? See the quality change as the shutter speed slows.

Available

Dust Analysis

Count the dust spots on the sensor and see how much they matter, before you decide on a clean.

Available

How to set it up

Setting up your EOS 80D for FoCal

Connecting the cameraMini-USB or Wi-Fi
  1. Use a good Mini-USB cable

    FoCal controls the EOS 80D over USB. Use the cable that came with the camera or a good-quality one, and avoid extension cables: a poor cable is the first thing we suggest changing if FoCal is unreliable.

  2. Or connect over Wi-Fi

    FoCal can also use the EOS 80D’s Wi-Fi. Turn on the Wi-Fi option for Canon in FoCal’s settings first, then see Connecting over Wi-Fi.

Permissions on macOSfirst connection

When you first connect, allow access to the Photos Library and to Removable Media. FoCal needs both to talk to the camera.

  1. If a permission shows as Denied

    In FoCal, open Help then Settings, expand Advanced and click Reset Application Permissions. Restart FoCal and it will ask again.

Connecting over Wi-FiCanon Wi-Fi

First: turn on the Canon Wi-Fi option in FoCal (Help › Settings, General tab), or FoCal won’t find the camera.

The camera side is in Canon’s EOS 80D Wi-Fi guide (PDF).

More on hotspot (“easy”) and infrastructure connections in the camera network help.

AF Microadjustment on the EOS 80Dwhere to find it
  1. Open C.FnII-16

    Press MENU, go to the Custom Functions and choose C.FnII-16. The picture may show a different C.Fn number: on the EOS 80D it’s C.FnII-16.

    Camera menu: the Custom Functions page with AF Microadjustment selected
  2. Choose “Adjust by lens”

    FoCal sets a value for each lens, so select Adjust by lens, then press INFO.

  3. Set the value

    For a prime lens, change the value on the screen.

    The adjustment scale for a prime lens

    For a zoom lens, select W (wide) or T (telephoto), as FoCal asks, and press SET. Then change the value with the rear dial.

  4. Save it

    Press SET to save the value, then MENU to go back. The values you chose are shown.

    The Adjust by lens screen showing the saved values
Your test space5 steps
  1. Choose a solid floor

    Ground-floor rooms vibrate less when people move about or traffic passes, and vibration affects the results.

  2. Fix the target to a wall at lens height

    Keep it flat so it can’t move. A FoCal Hard Target is what we use for all our development and testing.

  3. Light it well and steadily

    Avoid fluorescent and LED lights, which can flicker in a way you can’t see but the camera can, and changeable daylight. FoCal copes with small changes in light, not big ones.

  4. Use a sturdy tripod

    If your tripod has a hook under the centre column, hang something heavy from it. With big lenses, mount the lens’s tripod collar, not the camera.

  5. Set the right distance

    The Target Distance Tool in FoCal tells you how far from the target to be, with or without the camera connected.

Target Setup, FoCal’s guided setup, checks the position, light and settings before a test. More in the FoCal help.

Camera set-up4 steps
  1. Charge the battery to at least half

    Low batteries can make tests fail or the camera behave strangely.

  2. Take off any battery grip

    Grips add vibration on a tripod.

  3. Aim the centre focus point at the target

    Roughly is fine: Target Setup confirms the position.

  4. Cover the eyepiece

    This stops stray light getting in through the viewfinder and changing the exposure.

Camera settings8 steps
  1. Photo mode

    If the EOS 80D has a photo/video switch, set it to Photo.

  2. Wi-Fi off for USB

    If you’re connecting by USB, turn the EOS 80D’s Wi-Fi off: it can interfere.

  3. Remove any mode limits

    If the camera lets you limit its options, allow Aperture Priority and Manual, Spot and Matrix/Evaluative metering, and all apertures, shutter speeds and ISO values.

  4. Aperture Priority

    Most FoCal tests use it. FoCal asks if a test needs something else.

  5. One Shot autofocus

    Set the autofocus mode to One Shot: a half-press of the shutter button locks focus and then stops.

  6. A single, centre focus point

    No automatic point selection: you should see one fixed AF point, in the centre.

  7. Focus limiter off

    FoCal may use the lens’s whole focus range, so set any focus limiter on the lens to off or the full range.

  8. Stabilisation off

    Turn off any stabilisation on the lens: it can make the results less accurate.
