As for your question, I’m not familiar with the cams you mention, but I suspect they are relatively low-cost cams.

Based on my limited experience doing relatively low-budget wedding and event shooting, a cam’s low light (available light) performance is a critical consideration.

For example, Sony’s VX2100, PD170 (which have three 1/3″ CCDs) and DSR-370 (which has three 1/2″ CCDs) are able to record relatively good-quality SD video in typical, dimly-lit indoor wedding & event environments.

Cams with smaller or fewer CCD/CMOS imagers, or cams with noisy electronic gain circuits, or <$15,000 cams with relatively high-resolution imagers (HD or SD) are typically much less light sensitive and "clean-looking" compared to the VX2100, PD170 and DSR-370. However, if the events you'll be videotaping will primarily be outdoors or brightly lit, there's a wider choice of cams you might select from. Also, since a cam's built-in mic is rarely adequate in most situations, I'd also recommend selecting a cam which can easily and reliably connect to an external microphone when required, such as a wireless mic worn by a groom. High-quality sound accounts for at least 60% of the effectiveness of a video production. If at all possible, test the cam you're considering in the intended environment before making a final purchase decision. Good luck with your research! - Peter
