Shutter vs. Cineframe ? at DVinfo.net

Hello :)

I've just got my Z1 yesterday and doing all kinds of tests right now. So the first thing is wonder is:

Is there a difference between cineframe and normal mode with shutter set to 25 ?

If not I would prefere 25, as it's then more light sensitive.

Thanks !

You'll find that there's more inter-frame blurring with the shutter set at 1/25th.

Isn't that good ? For a Filmlook ?

And is it then also deinterlaced ?
Should be. Or how can you get 50 frames if the shutter opens only 25 times.

No, film camera shutters are only open half the time (for 25fps, that means, for a 50th of a second).

At video slow shutter 25th/sec, there is twice the motion blur that a film camera would have.

The FX1 deinterlaces slow shutter the same way as CF25, it just drops a field, and repeats the first field in as many subsequent fields as is needed.
