C100 Mark ii - Is the noise I'm experience normal?

[mmediacompany]

Dear Users, 

Please help me figure this out. For some reason, I'm getting a lot of noise when using the c100 mark ii. My settings are ideal. Please review the video below and let me know what you think. I wonder do lens add noise. Can one lens produce more noise than the other???? Please help.

Okay, I added a little more light to resolve the issue, but I thought I should be able to shoot under such condition.
