Excellent point. XL1 & 2, GL-2, Panny 100, etc. they're all good cams for their suited purpose, but none of these are event cams.
If I'm not mistaken, the VX-2100 has the same low Lux rating and low-light capability as the PD-170.
About the only time we had to mount our 50watt Bescor light was during an outdoor wedding, after dark, when the park lighting over the cake cutting event, burned out. If not for our light, there wouldn't have been a cake cutting.
