FreshDV has an interview with a developer from the Foundry, discussing a demo project they have to correct rolling shutter. It’s worth a viewing if you’re interested in the pros and cons of CMOS. I’ve had discussions with folks in the past about the sort of optical analysis necessary to correct rolling shutter in post, so it’s pretty cool to see it being done. Also interesting is his guess that within 2-3 years, rolling shutter won’t be an issue (in new cameras).
