Answers.Text: I see. It's really tough to say, and while a few reviews on the internet also indicate the problem you're having, the specs do claim control over manual focus. This shouldn't matter, but have you tried the non-automatic shooting modes (aperture-priority, shutter-priority, and manual)? Perhaps the camera is taking too many liberties on its own if you're in auto or P mode.

Body: <p>I am trying to take video for a time lapse of stuff I write on white paper. Issue is that when the paper is blank, it looses its focus automatically. Unitl something or some writing/drawing/object is put on the paper the focus will wander off. </p>
  
  <p>All this happens even when my camera is in manual mode.</p>
  
  <p>Here is a sample:</p>
  
  <p><div class="youtube-embed"><div>
                  <iframe width="640px" height="395px" src="https://www.youtube.com/embed/QqyjdMVa7g4?start=0"></iframe>
              </div></div></p>
  
  <p>First I want to understand why it happens, and, how to avoid it. I own a <a href="http://www.amazon.in/Canon-Powershot-SX520-Optical-Powerbank/dp/B00M0QVTOS" rel="nofollow noreferrer">canon powershot sx 520 hs</a></p>

  It looks like by default, that camera fine-tunes the focus (even in manual focus).
  
  From the [Canon support page](http://support-asia.canon-asia.com/contents/ASIA/EN/8202125600.html): To deactivate automatic focus fine-tuning when the shutter button is pressed halfway, choose -> [ [![Camera icon](https://i.sstatic.net/wTfaW.png)](https://i.sstatic.net/wTfaW.png) ] tab -> [Safety MF] ->[Off].
