nd-filter

i wonder about the built-in nd-filter that comes along with the xlh1 camera, if turned on, can you film briefly at the sun or do you have to put on an external filter?

I wouldn't. The 1/32 filter corresponds to a density of only 1.5. I'd want about twice that before I'd point directly at the sun.

You can also compensate for the intensity of the sun by choosing the maximum shutter speed.

I once shot a solar eclipse putting lots of layers of ND lighting gels in front of the lens, an affordable stop gap solution.

In the old days we were always advised to look at eclipses through a piece of completely exposed and fully developed black and white film which, as I recall had a density of about 3. I did it and I can still see (with trifocals) so a 1.5 with the 1.5 (1/32) on the camera should serve. I think the advice to rely on the electronic shutter is very bad advice indeed as this will not protect against heating of the CCD's. I suppose things are a little better in a 3 ccd device in that the energy gets split 3 ways rather than one CCD getting the whole brunt but remember that higher shutter speed does not reduce the amount of energy impinging on the CCD, only the number of electrons taken out (there is no mechanical shutter AFAIK).
