This feature is highly touted and
important to event and wedding videographers, but I do not use a camera
in low light. If we are setting up for a corporate shoot, or a commercial,
or a documentary, or even for a news event - we set up lights. Our crews
make sure there is plenty of light to insure we can chose from a variety
of shutter speed and apertures. More light not only gives you more choices
but better control. More light generally improves the quality of the picture.
In the rare cases where you do have too much light, it is easy to control
with a ND or by techniques like flagging. OK, now I am getting off my
soapbox and on with the story.
The following are pictures taken with an old model XL1 and the new model. The lighting remained the same. This test compares shots taken at various exposures with the XL1S with a "control" picture taken with the old model. Find the picture below that is the closest match to the single picture above. |

It looks to me like the new camera had to be stopped
down about two stops to match the brightness of the old camera. That means
the new cameras are two stops more sensitive. Remember, two stops is equivalent
to fours times the amount of light. So it looks to me like the new model
can shoot in ONE FOURTH the light of the old model and get the same results.
Note that the test did not include using the NEW gain settings. Kick in
the new gain settings and the new model can shoot in about one tenth the
amount of light. Here some samples of the gain.
