does the z1u have delayed recording, say to capture a sunset or sunrise? What kind of filter would you use?

When you say 'delayed recording', do you mean timelapse? Best to shoot sunsets and such-like in real time, then speed up in post. That way you can smoothly vary the frame rate and not have to decide frame rates on the wind-swept mountain top.

If your camera genuinely needs protection (from dusty atmospheres, sticky-fingered children etc), then do consider fitting a UV filter. Make sure that this new front element has the very finest super multi-coating you can buy though.

For all other times don't use a filter. It's degrading, unnecessary and reduces the efficiency of your stock lens hood.
