I just picked up that lens. Great build quality and nice bokeh. Also note that when you have a full 35mm brevis/redrock/letus adapter on your HVX, that sucker is big! Not as easy to back up against the wall as will be the Af100.
The Voigtlander 25mm f0.95 will get you as shallow as you'd ever want to be on the AF-100. We used their 50mm f1.1 for a low-light interior scene, and it looks glorious. If you need speed, you have options on the AF-100, that's for sure.
