Steven,

Just looking at the pictures in the body of the article, it's clear the EX is underexposing (by comparision).

And if you download the G1 and EX 1080 30P images and switch between the two, you'll see the EX is significantly darker.

That said, yes, I do absolutely agree the EX has considerably more lattitude. I just feel this comparison makes the G1 and HVX look a little worse than they actually are.

EX1 1080p30 blew away the competition! These sensors are what 1080p60 need! in 4:2:2 is even more awesomer for that. And heck, 4:4:4 in 1080p60 over Dual 3G HD-SDI would be awesomest!

Agreed. I think everyone will agree that the EX1 is certainly stronger in the area of resolution. But not that much better than the Canon. I have to give credit where it's due. Look at the BMP's and compare the area of the green bottle near the leaf and lower left FIOS label. The Canon actually does a better job there than the others. Overall, the EX1 looks excellent, but it doesn't leave the Canon in the dust. Nobody sits and looks at stills from these cameras and we've all seen great imagery from all of them. Don't get me wrong, I have an HVX and I'm on the list for my EX1 but it's not a Canon killer or HVX for that matter.

Well, it's true -, "beauty is the the eye of the beholder"
The 1080ii stuff was close with the Canon, but the EX1 latitude was better.

The EX1 1080 30P was in another level from the other cams

True, but there are a few lingering ?'s about the EX. One is the preponderance of green. I know it can be toned down in the camera, but may be a result of the ClearVid sensor, which uses more green and less red and blue pixles than other types of sensors. I'm not so sure if this doesn't have some drawbacks.

Another is the EX's slightly more "processed" look, to my eye. Totally subjective, but the shots do look a tad more "video" to me and lacking of some depth. Now that could be a result of the exposure and having fewer hot highlights, but again the ClearVid requires some extra camera processing to make it work properly. So maybe that is causing a slightly more processed (again, very subjective) look.

Steven Thomas November 27th, 2007 10:12 PM

I'm seeing absolutely none of what you mentioned.
Actually the EX1 1080 30P has the most natural look out of the frame stills.

I've seen you make this reference before.
IMO, these are not good examples for the other cameras. The EX1 1080 30P is in a COMPLETELY different league. It has FAR less noise and artifical detail and ton a lot more detail. I'm not finding this image below subjective, that's for sure.

As far as I know clearvid is not used on the EX1. Clearvid and CMOS are not the same thing. There would really be very little reason to use clearvid on this camera since the chips are native 1920x1080 to begin with. The EX1 will use a straight ratio of aligned RGB pixels from the chips so there should be no larger amount of green pixels used. Adjusting the color in the camera should fix the green tint.

Thomas,

You may well be right about ClearVid's pixel strategy not being used on the EX1. Reading up on it, it has an Exmor sensor. Which may or may not (I can't find out for certain) use the ClearVid pattern.

Tom Roper November 27th, 2007 11:53 PM

Recanting my post. I had the HVX image and the EX image mixed up. Ignore me, sorry.

Steven,

Look at the Rasta shot at 30P for the G1 and the EX. To me the G1 looks more natural and less plastic. Perhaps it's due to the highlights being hotter, which actually adds some extra depth.

Steven Thomas November 28th, 2007 08:48 AM

My bad for posting the HVX / EX1 bitmap.
You are right that the G1 and EX1 both look good.

If you think the G1 looks better, than that's great.
The G1 is a an excellent camera.
