It's more than just aperture, though. F/2 on a wide-angle lens like the iPhone won't give you the same impact as F/2 on a telephoto. Most low-cost HD video cam

Most low-cost HD video cameras have severely compromised lenses, and professional cameras tend to have extremely expensive lenses. Red solved the problem by tapping into the Canon/Nikon lens base.
- randyrand 13y agoIt's not about field of view (a f/2.0 wide angle and telephoto shot both have the same DOF in terms of actual length - telephoto just appears to have a shallower DOF since the image is cropped.) DOF is actually a physical property of sensor size and aperture size. http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm http://www.cambridgeincolour.com/tutorials/digital-camera-se...
