... It is my understanding that the "rolling shutter" issue only occurs with CMOS sensors. The so called "global shutter" which you claim is a solution is not without it's problems.

I am not aware of any consumer or prosumer video camcorder which uses the so called "global shutter", ie; those applications where CamcorderInfo users and other Videography publications would be interested.

Can you show me any CMOS camcorder with the so called "global shutter" which costs less than $1500?

The rolling shutter issue does not appear to be Canon specific problem, so is there any reason why you continue to preach the issue in regards to the Canon HV20? And now you are bringing up the same issue as well as others by the mere announcement of the upcoming Canon HG10?

Your constant droning on many of these issues are becoming annoying.

Rich.

Yes "rolling shutter" is a feature of only cheap CMOS sensors. No I'm not aware of any camcorder which uses "global shutter" solution to the problem, but nor was I aware of any HDV CMOS consumer camcorder 3 years ago. There are plenty of industrial cameras though that have that feature (pattern recognition don't work very well if your camera distorts geometry of moving objects).

No I don't know that "global shutter" has other problems, hopefully they are not of such nature as to preclude it from being used in video camcorders. Can you elaborate, educate us?

Finally you need to push, cajole, moan, etc to get the industry to do anything, e.g. thanks to this site's constant prodding new camcorders tend to address problems users droned about ad nauseam. Read the self congratulatory section on the zoom rocker in this review for example. It didn't get there by accident. Hopefully constant harping by CamcorderInfo reviewers about poor quality of Canon's hand straps in their recent cc will get the issue resolved one of these days.

All said and done, we still need a solution to the geometry distortion problem in this and other CMOS camcorders, it's that simple. The problem is too serious imho.
