What exactly is a rolling shutter effect, I have seen it mentioned several times but never understood what it meant.

Dude - In reality (and I shoot about 45 weddings per year and around 15 with the Z7 so far) it's not a problem. You even see it on TV as most reality show footage is shot with rolling shutter cams. I've never had a bride ring up and say "Hey, what's with the rolling shutter artifacts knobface!"

John, the demo explains whta rolling shutter effect is, but it is shonw in slo-mo, does anyone have a real time clip they can upload to demonstrate the effect.

OK, thanks Robert.

BTW, you may also want to look at the EX3 camera, this would seem to be a better buy, albeit more expensive.

I think the ex1 and ex3 are awesome cameras but am not ready to go tapeless workflow just yet. I love the feel of a miniDV tape in my pocket

I too like the MiniDV format.

That is untill you have one or two snarl up in the camera, this has happened to me twice this year. I also like the ability to quickly download clips rather than wait for the 1:1 transfer times of tape.

I guess we are all becoming spoilt, no so long ago we would have had to send film of to a lab for processing.

Thank you, John, from the bottom of my heart for a great laugh. Made my day and it's only 9:30am.

This is the best article I've read that explains the CCD vs CMOS // roller-shutter issue, with screenshots and video examples from the Z7U:

You can handle it Robert - us wedding videographers need thick skins!

Agree - and remember the EX series do not shoot SD, and you'll need an editing system that can handle the extra workload of full 1920x1080 footage. PLUS, although promising much cheaper media cards than P2, I was disappointed by the high prices of SxS media.

Robert - I'm shooting a wedding this weekend and the photographer is flash-happy. It's also in quite a dim church, formal photos will be near dusk, and reception is low-lit. I'll make a real point of looking hard at this rolling-shutter issue and post some raw footage for you.
