question is while measuring light with the lightmeter what ISO should I set the sensitivity at?
will shoot at 24p, standard shutter at 1/60 (im kind of new to the ntsc system- but i gatther this is right)
also will be using lens adapter for 35mm lenses. so am wondering how this will effect the aperture- do i loose a stop or two by applying the lens? what comensation should i make/ if any?

also wondering if i should go for progressive or interlaced for best quality picture- might be blown up to 35mm.

thanks,

Given the factory specs, it will be roughly ISO 800.

Not sure about loss due to the lenses... though its easy enough to try them on and find out. :)

From several threads I have read about measuring the ISO, at 24p and 1/48 shutter the camera is around 640 ASA.

Btw - 1/48 is the default shutter rate when set at 24p.

Yes, you will lose light using a 35mm adapter. How much depends on the adapter. I have a Redrock M2 and lose about 1 stop of light. Your 35mm lens(es) will also need to be considered.

If you plan to use a 35mm adapter then plan on using a lot more light. Also be sure you or your DP is familiar with and sets up the 35mm adapter correctly. In the case of the M2 it takes a lot of fine tuning before it's dialed in. Although once that is done it creates some great images.

also wondering if i should go for progressive or interlaced for best quality picture- might be blown up to 35mm.

Shooting 24p advanced is recommended for going to film. Here's some info:
