Hi,

according to panasonic, the 4,2mm to 55mm equals 32,5 to 423mm - crop factor would be 32,5/4,2 = 7,73 (which is a bit weird, because the crop factor of 1/3" models should be 7,21 according to Wikipedia - http://en.wikipedia.org/wiki/Image_sensor_format

please google first if you want to know something: i googled hvx200 shutter speed and found this: http://www.dvxuser.com/V6/showthread.php?182847-HVx-200-and-Shutter-Speed-options

Killer, welcome to DVXuser.

16:9 = aspect ratio

The focal length in mm for a video cam is not the same as it is on a slr type cam due to different sensor size. As mentioned above, there are conversion tables or formulas, since the 35mm equivalent is more common.

There is no "proper shutter speed". A common shutter speed is 2x the frame rate. So shooting 24p frame rate, you might select 1/48sec for the shutter. There are many times you might deviate from this, for example fast action or if you need more light.

If you don't have it, the Barry Green book about the HPX170 will answer every basic question about this and the cam. He is a site founder and participates here all the time.
