I'm looking at buying an HMC-150 and was curious about whether the HMC-150's lens has a constant aperture throughout the zoom or if it's like the xh-a1 where the lens closes down as you zoom through it.

If it is a constant zoom, what is the widest aperture? If it's aperture is variable, what is the aperture at the widest end of the lens to the telephoto end of the lens? Thanks much.

I don't think you're going to find a video camera anywhere this price bracket that has a constant-aperture zoom. Even ones that claim to be constant aperture (like the HD100 and the EX1) still "ramp" the iris at full telephoto. It's just something you have to get used to in this price bracket.

The HMC150 is 1.6 at the widest, 3.0 at full tele.

Tall_sided, one thing to keep in mind with the HMC150 is that if you manually choose an iris setting of 3.0 or higher, this will be maintained through the full zoom range, so you don't have to worry about exposure changes during a full zoom rack.
