Hi to everybody...
I'm new proud user of this cam. I really like it, from mx500 to 170 ther's a lot of difference I can see it without any difficult.
Only few questions, I don't know this cam...
When I choose zebra 100%, I see the overexposed areas...ok no problem; but I see I the one thing is overexposed and I pan the camera, when the object is near th edge of frame the zebra disappear..it is right?By doing other test I found the zebra change if you move the camera by panning ot tilting...obviuosly I put all in manual...
th end search button works only with sony pd170 record?For example yestarday I do some test with a mindv used only for 20 minute...but I start to rec before the end of tape and I finish 1 minute before the end of lat shooting. So when I press end search, pd170 found the end of its shooting, not the real end...
Dvcam I understand should be a better format, but dvcam tape are to expensive for me...could I record in dvcam mode to a minidv tape? Doing this give some benefit?
I usually use fuji minidv tape, it's a good choicein your opinion?
thanks and bye...

Zebra stripes show you how much is overexposed at your current setting. If
you set it to 100% it will show you all areas that are clipping and cannot be
recoverd.

If you pan the camera the areas that are overexposed should change, and
thus the zebra stripes will move with it as well. If you pan away from the
over exposed areas the stripes will disappear completely. If you pan to new
over exposed areas new stripes will appear.

Some goes for changing exposure (either by changing the lights [or the sun
goes behind clouds or comes back etc], changing filters, shutter speed, gain
or iris opening [f stop]) etc.

At maximum aperture and the next stop down (at whatever focal length youre shooting at) the lens vignettes the image. This is perfectly normal (all cameras do it) but the zebra stripes do indeed show it up. At f1.6 the edges of the frame are a good 1.5 stops less exposed than the centre.
If you do the same pan at f8, say, you'll see the zebras remain constant across the frame.

You can use Fuji tape or Maxell or TDK or JVC. I use Sony, but hey, whatever you do, stick to one brand, ok? There have been countless sad stories from those who constantly switch brands.
