While up at the Panasonic HQ, I took the opportunity to test the two cameras for infrared (IR) performance. It's a well-known issue that the EX1 sees into the infrared portion of the spectrum, which has the effect of turning black objects into brown or purple. Adam Wilt did an excellent infrared comparison among various cameras to try to test the performance of infrared-cut filters like the 486 or "hot mirror" filters.
So, with IR being a "hot topic" (ooh, a minor pun there), I wanted to see how the HPX300 performs as compared to the EX1. Being Panasonic's first CMOS camcorder, I expected it might show some IR contamination.
Accordingly, I had my wife find every stitch of black fabric we could locate. I took up her dresses and my socks and a tie and some of her quilting fabrics and, basically, anything and everything black. I couldn't find anything quite as scintillating as Tim Blackmore's shirt, but I certainly found enough to test with.
Both cameras were set to the same exposure, gamma, white balance, and color. All the objects in these photos were black. Both shots were taken simultaneously, under identical lighting (tungsten light from a Lowel DP light).
Here's how the EX1 rendered them:
And, in comparison, here's how the HPX300 rendered the exact same scene:
The results show the HPX300 to be substantially superior in IR rejection and shouldn't be needing any Infrared filters to properly render black colors. The HPX300's rendition looks exactly like it did in real life; the EX1's rendition is way off.
These frames are direct from the footage, no post processing involved (other than to shrink them to 50% size). The white balance was manual; the exposure was set by a waveform monitor.
