I have few complaints about this camera. The color viewfinder makes it more difficult to see contrast. Are there any simple solutions to make the veiwfinder monochrome. I had tried gels with limited success.

Unfortunately, the GL2's viewfinder is strictly a color LCD. But here is a closely related thread (http://www.dvinfo.net/conf/showthread.php?s=&threadid=24017) in the Panasonic DVX forum that might offer you some guidance.
