I have been reading the review of the Canon EOS 1300D by The Digital Picture and I came across this

As with the T5, the T6 image details in the color block comparisons are very slightly smaller than those from some of the other 18 megapixel DSLR samples. This is because the T6's Live View display does not provide quite a 100% view, causing the test target to be framed slightly wider than other models.

What exactly being "widened" mean? Why does that happen?

It isn't actually the live feed that gets widened, but the resulting photo:

It appears that the live view does not display the full frame as recorded, just as the viewfinder only provides 95% coverage. Why LV is designed like this, I cannot say.

This means that, when they shot their test chart so it filled the LV, the actual photo recorded a bit more on the sides. This is what they mean by "framed slightly wider".

As a result, the blocks of the chart are a bit smaller in the photo as with a different camera with the same MP which framed the target narrower.


The rear LCD appears to have a resolution of 1280 x 720 (921600) pixels, which is smaller than a HD video of 1920 x 1080 pixels, meaning it can't display the video at full size. The video must be reduced to be shown on the monitor. The simplest way to do this is to simply crop the video, which means information on the edges will not be seen. The recorded video will be wider than what is seen on the monitor.

    \$\begingroup\$ This answer, though accepted, is factually wrong. the Q isn't even about video. \$\endgroup\$

  • \$\begingroup\$ @ths Live View means showing a video stream from the sensor. \$\endgroup\$ Jul 25, 2019 at 13:06
  • \$\begingroup\$ Also, 1920×1080 and 1280×720 are both exactly the same aspect ratio, so this doesn't even make sense. \$\endgroup\$
