to make a long story short :

If u don t

shoot fast pans or movement

If u don t shoot where flashligths or strobelights may occure

If u don t shoot handheld a lot

#then the ex 1 is a real sub10 k beast

*hugs math and stevet* its okay guys ;)

Imagine how a new purchaser of the hvx will probably feel in a sony forum in the midst of the EX release! I think this forum is very fair, very welcoming etc

I just recently heard about these issues with the EX1, mostly from Barry Green's analysis thread. Too bad, the EX1 was looking to be a really good buy. The strobing issues are fine, all the new CMOS cameras have that problem, even my HV20 and even the RED camera it seems, so I'm not worried with that. What does worry me is the panning thing, if they purposely implemented that then the only question I want to ask is what were they thinking?
 
It's an amazing camera. I sold my HVX200 to buy one. It was worth it. It's a lot like the HVX, just higher resolution and a kick arse LCD screen. I have no regrets.
 
to me all those things that are pointed out that a "user cant perform with the camera" are a instant warning sign not to make that purchase. Regardless if the user is a panasonic,sony,canon etc user.
 
The panning issue is pure nonsense. I am being polite here. The camera does not lose resolution while panning.

I trust Barry's insights in most cases, but even he said that he could not confirm what was happening. He later went on to doubt his assertion further (but has not, yet, retracted it). Read his later posts in the thread. I appreciate what he has done in his review, but think his first description in a bit sensational:

"So the first thing I looked at was sharpness. And oh yeah, the EX1 delivers on that. 800 observable lines of horizontal res on a Chroma Du Monde. Fantastic. Er, just don't move the camera. Move it, and you get a noticeable resolution drop, more than can be accounted for through simple motion blur. And it's not due to the codec either, you can see the effect on the live output and you can see it on a scope. Heck, you don't even need that -- you can see it right on the (as already acknowledged, excellent) LCD! Just turn on peaking (especially in yellow -- excellent feature, that peaking-in-yellow!) and point at a high-detail scene; take it outside, put it on wide-angle and point at some trees. You should see a whole lotta yellow, because the peaking is showing all the sharp high-frequency detail, right? Now pan, and -- whoops? Where'd all the yellow go? You'll notice the peaking disappears whenever you move, and comes back when you stop. Well, so does your hyper-sharp resolution -- it all disappears whenever you move. The faster you move, the more it drops, and that may be attributable to motion blur, but even very minor moves cost you a couple hundred lines of res. So in motion, the sharpness advantage over an HVX is very little. I have theories as to why (I think it's doing some manner of aggressive noise reduction, perhaps through frame accumulation) but I don't know for sure and I couldn't find any other way to verify my suspicion."

I feel like Barry and his associates may have been expecting the look of a 180° shutter but were looking at an image with shutter off. I am sure that Barry intends to do further tests, and I think he will come to the conclusion that it isn't happening, or if it is, that it's nowhere near "a couple of hundred lines of res."

Given the weight given to Barry's (formidable) expertise on this site, he should have been more responsible with that assertion, because it is being parroted by many people who have never even seen the camera, let alone done any testing or comparison with it.

I own the camera and have seen nothing like what Barry described. I have conducted some rudimentary tests that can be seen here:

Look at the res charts up close, in Photoshop.

I dare not, then, point out all of things that you can't do on an HVX200. Not on this forum, anyway.
 
Yes, I already confirmed the panning is a non issue, well short of fast pans that cause skew due to the rolling shutter... But , heck we're living with it. It's there, for sure.
Someday, I might perform a better measurement of panning verses skew, but I'm shooting a lot of jaw dropping footage. I can live with this until something else comes along. ;)
If you tracking motion, it could at time cause issues. It really depends, as the RED users are also finding out. BTW, I'd buy the RED ONE if I had some extra cash laying around rolling shutter and all!

We've been looking at EX1 moving footage closer over the last week and it looks awesome. Nothing any softer than my other cameras, in fact it's looks sharper if anything.

Matthew, I'm with you on the EX1 panning assertion, but like you mentioned, I believe Barry has already set that straight since then.

If there was some sort of processing slowing down the image response time, your example rez image would of also went soft during the pan. It does not; therefore, it's a non issue.

In fact, even the Factory stuff posted over another forum, looks like solid 24P motion and it's associated blur. It's been recompressed, but still looks good.
Usually 24P pan moves like this are avoided, but it gives you an idea. There is a definate difference between the EX1 720 and 1080 footage. This was shot in 720P, but I sure would of liked seeing it in 1080P. The 1080 off this camera is excellent.
