Filmed gig on EX3 and no rolling shutter problems!

Perhaps new firmware on this and the EX1 has made a difference but I am over in Siberia making a doco and oddly filmed the legend that is Deep Purple in concert and then fireworks, strobes, flashes everything and looking at the footage got no visible half frames...

Has anyone else had better results recently with flashes? Or did I just get really lucky with every shot!? I shot a wedding for a friend 2 months back on the EX1 with old firmware and had half frame flashes galore...grim.

I did shoot using the Canon 20x 1/2" HD lens but that wouldn't have made a difference...

Certainly on my recent lightning shoot with the EX3 there were very few partial frames.

Have to ask the engineers at IBC. See you there, 2pm every day on the Sony stand.

Some of that footage for our viewing would be a good thing. Sounds promising!

Would that mean that the SKEW issue is improved too?

Seems unlikely but that'd certainly be cool!

Phil,
You are the second person that mentioned this..
I read a similar response on this forum:
http://www.dvinfo.net/conf/sony-xdca...-exposure.html

Hmmm...
If it's improved, I wonder how?

So it isn't just the EX3. Weird that Sony haven't publised this as it's a MAJOR improvement. Unless of course it is a side effect of something else they have done...

Very interesting possibility, that of a firmware to improve on a considerable flaw.
One of my biggest concerns with the EX-3 is that of the rolling shutter issues.
I have problems using the EX-1 with the older firmware shooting a concert and later on a moving car (jellovision), so I'm really excited about improvements on a, otherwise, fantastic camera.

it's still there. Done flash at lens test. As bad as ever, but the gig footage coped really well. Odd.

Will post a clip to show asap

Maybe they still have some Soviet Era Speed flashes over in Siberia.

It did seem to good to be true..

Concert lighting stobe effects are usually done with mechanical shutters which are slower.
I have Martin and Elation moving head stage lighting that use mechanical shutters. The EX1 has no problems with these lights.

It figures.
Just talked to a friend today in SF and he told me of his experience operating cameras on a recent Music Festival in Golden Gate Park. The bands that use newer LED lighting technology, Radiohead for example, had really bad issues with rolling shutter cameras. The old style strobes did well. He also mentioned the comparable more intense output of the LED based fixtures which made proper exposure much harder.
I've pointed him to this forum.

This definitely sounds like the flash duration is the culprit. I might have to dig out some of my older studio strobes along with the hotshoe-mounted types and do some comparisons.

Very true...
Also, some LED technology can cause flicker with ANY camera based on how LED lighting is dimmed.
I've fought this with different cameras, not just the EX1.

LEDs use PWM (Pulse width Modulation) to reduce their stay on time. Based on their circuit design and speed can cause flicker issues. I have to leave my LED lighting at full or it will flicker. Some high end LED lighting does not have this issue.
