I wanted to know what filters can I use to protect the front of the lens. I am planning to take the cam to the beach soon.
Setting the focal length is only needed for legacy lenses with no electrical connection to the camera. With the native :43: lenses let the camera take care of this automatically.
hahaha have you tried it with video?
It doesn't work any better, it sits there bouncing the lens back and forth even when things are still in focus.
I think things will get better in the future... but I'd agree with the plethora of postings suggesting that it's best to use manual focus in video right now.
