Canon 80D Experience
Release Shutter Without Card
This setting prevents you from taking photos if there is no memory card in the camera,
and is typically used for camera stores to demo the camera even without a memory
card inserted.
Disable. Please! You do not want to take 800 images of your niece's wedding and
discover there was no memory card in the camera (see Figure 35 - left). Test it to make
sure you set it properly.
Figure 35 - Left: Be sure to Disable the "Release shutter without card" setting so that the
camera will not take images unless a memory card is inserted. Right: Lens Aberration
Correction menu for the camera to automatically correct for lens issues when using
Canon lenses.
Lens Aberration Correction
These menu options can be used to automatically correct images for image quality
issues introduced by the optical characteristics of some lenses. The correction
information for 30 Canon lenses is available, and you can use the included EOS Utility 3
software to enter the data of other lenses.
Peripheral Illumination Correction will correct for darkened corners of an image that
occur with certain lenses or at certain focal lengths, such as when using a very wide-
angle focal length. If you wish to use this setting, attach the lens then access this menu
to see that the correction data is available, then set for Enable (see Figure 35 - right).
Using this option may introduce digital noise to the area being corrected. This correction
can also be made with the included Digital Photo Professional (DPP) software, which
contains Canon lens profiles, as well as the latest versions of Adobe Camera Raw and
Lightroom which also include specific lens profiles. The in-camera correction amount
will be lower than what you can apply in DPP.
Chromatic Aberration Correction is color fringing caused by different colors, which travel
at different wavelengths, not focusing at exactly the same spot on the sensor. This can
cause an image to appear less sharp and to have fringes of color along light/ dark
boundaries. As with above, if you wish to use this, attach the lens before accessing this
menu to see that the correction data is available before setting for Enable.
