Basically I own a nikon d3000, and I'm planning on getting a fisheye, I was going to get the sigma option with the af motor, but a friend said that the sigma is the same lense as the samyang etc, just badged up differently (and without the motor) an you don't really need af for photos (skate related), the only thing I'm now worried about is..I'm planning on upgrading my camera itself at a later date to the d7000 so I can make edits(skate videos)
So my question is really, do I need an autofocus lense to shoot video footage!
