Canon EOS REBEL T5 Instruction Manual page 287

Horizontal stripes appear, or the exposure
or color tone look strange.
Horizontal stripes (noise) or irregular exposures can be caused by
fluorescent light, LED bulbs, or other light sources during viewfinder or
Live View shooting. Also, the exposure or color tone may not come out
properly. A slow shutter speed may solve the problem.
The standard exposure cannot be obtained or the
exposure is irregular.
During viewfinder shooting or Live View shooting, if you use a TS-E
lens (except 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 the exposure may be irregular.
The continuous shooting speed is slow.
Depending on the lens type, shutter speed, aperture, subject
conditions, brightness, etc., the continuous shooting speed may
become slower.
The maximum burst during continuous shooting is lower.
Under [53: Custom Functions (C.Fn)], set [5: High ISO speed
noise reduct'n] to [0: Standard], [1: Low], or [3: Disable]. If it is set to
[2: Strong], the maximum burst during continuous shooting will greatly
decrease (p.261).
During WB bracketing, the maximum burst for continuous shooting will
decrease (p.130).
If you shoot something that has fine detail (such as a field of grass),
the file size will be larger and the actual maximum burst may be lower
than the numbers listed on page 85.
