Canon EOS M2 Instruction Manual page 133

When shooting, note the following:
Shooting Result

If you take the picture in magnified view, the exposure may not come out as
desired. Return to the normal view before taking the picture. (During the
magnified view, the shutter speed and aperture turn red.) Even if you take the
picture in magnified view, the image will be captured in the normal view.

If [A3: Auto Lighting Optimizer] (p.153) is set to any setting other than
[Disable], the image may look bright even if a decreased exposure
compensation or decreased flash exposure compensation is set.

If you use a TS-E lens (other than the TS-E17mm f/4L or TS-E24mm f/3.5L II)
and shift or tilt the lens or use an Extension Tube, the standard exposure may
not be obtained or an irregular exposure may result.
Image on the LCD Monitor

Under low- or bright-light conditions, the image may not reflect the brightness
of the captured image.

Even if a low ISO speed is set, noise may be noticeable in the displayed
image under low light. However, when you shoot, the image recorded will
have minimal noise. (The image quality of the shooting screen is different
from that of the recorded image.)

If the light source (illumination) within the image changes, the screen may
flicker. If this happens, turn the camera off and on again, then resume
shooting under the actual light source.

If you point the camera in a different direction, the image brightness may
change greatly momentarily. Wait until the brightness level stabilizes before
shooting.

If there is a very bright light source in the picture, the bright area may appear
black on the LCD monitor. However, such bright areas will be recorded
properly as a bright area.

In low-light conditions, if you set [52: LCD brightness] to a brighter setting,
the image on the LCD monitor may develop chrominance noise. However, this
chrominance noise will not be recorded in the image.

When you magnify the image, the image sharpness may look more
pronounced than in the actual image.
Lens and Flash

The focus preset feature of some lenses cannot be used with this camera.

Firing a modeling flash is not possible with the camera.
