Also, I have never figured this out....What is the difference between digital and optical zoom...for example, I am looking at the specs, and it says 5x optical zoom, and 2x digital zoom...what does that mean.

Jcs .... There is a slight lag when taking pics which at first really got on my nerves, but you gotta learn to move with the aircraft
All you need to know about this "digital zoom" is don't use it ... i've fallen for it a few times and the quality is awful ......
Apart from that the F707 is a superb bit of kit, you wont regret buying ...
Also, certain cameras can come advertised with "digital" and/or "optical" zoom.
For example, I have a video camera that has 40x optical zoom and 200x digital zoom (and camera companies love to bring out the "wow!" in people).
Pressing the zoom-further button moves some mechanical "telescope-lens" to about 40 times compared to where you started. After that, a digital computer inside the camera takes over and zooms the image on-screen to about 200x the original-- analogous to as if it had Photoshop built-in it to enlarge the photos:D.
This is the reason why EGFF complains that "digital zoom" brings about poor-quality images. Digital zoom uses a computer chip (inside the camera) to zoom.
Again, the word "digital zoom" is there to bring out the "oohs" and "aahs!" in customers buying cameras -- for the manufacturers, it means more zoom.
Hope this help clear things up!
