Just Checked out the Ex-1. Looks Good to Me.

I just spent a couple hours at Abel Cine Tech with a salesman, tossing and shaking the demo camera around like a madman, trying to recreate the rolling shutter problem. I didn't test any strobe lights, but I did run around with it in my hands, jump off some stairs, kick the tripod a bunch, whip it around in circles, and throw it through a window.

Okay.. I didn't throw it through a window, but you get the idea.

My impression is that the EX-1's rolling shutter issue probably does exist in some rare scenarios, but is mostly dramatized in the same way that the noise issue was with the HVX. When the HVX first hit the market, people were screaming left and right about all the noise, with many claiming that it was almost unusable in low light. Then people began to calm down and actually spend their energy making things with the camera.

I'm not biased towards any brand, and in my opinion the EX1 is a fantastic camera. Like Barry said, accessing the thumbnail clips took some time, but nothing too drastic. In fact, it took about the same amount of time as opening a mini DV tape and placing it in a carriage. Plus... the EX1 has an interesting feature, where you can access the last few clips in camera mode. So if you want to review your last shot, you can do so without entering VTR mode. That saves a lot of time (more than the HVX) and is a great feature for previewing shots for directors.

Now that I've played around with it,
I am going to buy this camera.

I currently own an HVX. I plan to put the EX1 on layaway,
and have fun with my HVX until the time comes to depart.

The last Sony camera I owned was a Sony CCD-V5000 Hi 8 camera.
After that came a Canon L2.
Then came the Canon XL1.
Then the DVX100a.
And finally the HVX200.

I'm looking forward to playing around with "the Sony look" for the next year or two.

And then heck... maybe Red, JVC, or ARRI next!
The more instruments a musician plays with,
the more versatile he becomes!
Bring it on Sony!

rolling shutter

I just covered a fashion show today as part of fashion week here in NYC, lots of flashes EVERYWHERE. Shot everything with 1/48 shutter, watched the footage tonight, only saw 1 or 2 times throughout the day where I got a gnarly blown half frame...overall it was not objectionable.

On a completely unrelated note, we had an an F900Rw/ a fujinon 4.5mm WA HD-zoom for our steadicam op...

On a panasonic 17" monitor we set up the F900 and the EX1 both with HD-SDI, and the EX1 was incredible in comparison. Overall image quality was VERY VERY close. I actually felt like I was happier with the EX1 because I was able to "dial it in" with ease. If I had a DIT or an engineer maybe I could've pushed the f900 harder, but why work so hard?

I'll never rent an f900 again....well maybe until Abel gets the damn zoom controllers for the ex1.
 
Shutter off makes the effect less likely, in a statistical sort of way. It lowers the probability that a given flash will partially expose. But when the effect appears, it's just as bad.

Well, sort of. if your shutter is 1/60 or less, the partial exposure will extend from the top or bottom of the frame to some point in the middle of frame. More than 1/60 and the partial exposure will be a slit somewhere mid frame.

Never use higher than 1/60, as that will cause every flash that is visible to camera (and not all will be) to be a partially exposed one. This is because there is no one moment when the entire sensor is being exposed at the same time.
 
I wish I could see some footage shot at 720, 60p (Shutter Off) to see the effect of the lower half of the frame over exposed by the flash, followed by the next frame with the top half over exposed. At 60 FPS, I'm not sure how the eye would see the 1 frame offset in the flash from the bottom to the top of the image.
