7d dynamic range against the 5d

From the clips I've seen so far, it seems like the 7d is not handeling highlights as well as the 5d. does anyone else see this or is it to early to tell?
 
Still too early to tell. But still, it's not expected to handle highlights better than the 5D.
 
seems pretty damn good to me. A little curve adjustment in post will help.
 
having learned from HDV, anything that improves that is a blessing. And at a fraction of the price. Wooo
 
I am sure most of the sample footage from the 7D you are seeing are default picture setting that have not been flattened, 5D highlights look like that too until you tweak the in-camera settings.

there's a huge difference between say the f350 and the cheapest sony. i know what you mean but hdv holds highlights just as well as mjpeg, h.264 or any other 8 bit video codec. it's all in the sensor and to some extent the raw processing.
 
Has anyone done any Dynamic Range tests? (stops)
How does the 7D DR compare to that of Mr. 5D?
If my memory serves me correct, the 5D has something like 8-9 stops of DR, right? RED One territory, so I'll be happy if the 7D comes close.
 




5D may have a very slight edge. Regardless, it's close enough. Judge for yourself.

The specular highlights in the metal are reflecting a bright California sky.

The first video shows me pushing the image highlights VERY far. Check the falloff.

5D and 7D are near identical in image quality.
 
You can see where the highlights get clipped pretty easily, but the rolloff on her face is not unattractive or too abrupt. Can't really tell the dynamic range, but it gives us an idea of the tonality of highlights and over-exposure on a Caucasian human face.

Right right. Reem seemed more concerned about highs (which I am as well) so that's why I posted those up. More soon, though!
 
With video chips it's always the highlights that are more the problem anyways. You don't owe anybody here anything though.

Any test posted here by anybody should always be considered a gift. You don't find me running out and buying a brand spanking new camera and using up my time posting stuff ;).

Thanks for the test so far Kholi. Really appreciate the fact that you've been helpful with these samples. Not everyone has $1700 to drop right off the bat to be able to play around with a camera! =)
 
I don't either. =T Hence why I now have to learn how to operate with one arm; pulling focus for myself is a biotch!

Quoted for truth. Thanks for posting those Kholi.

While we don't want you stressing out over testing I am sure you will run a few tests for yourself. So if you end up making any split screens for yourself to be able to compare easily, then it would be appreciated if you could also throw them up on Vimeo or something. I got server space and bandwidth to share if necessary.
 
Hello, I found your post via google when I was myself searching for information about 7D dynamic range :-))

I took pictures in RAW of the same scene with the 5D mark I and the 7D and overexposed them by 1,2 and 3 Ev to blow highlights then I corrected them them back in ACR.

Color maybe not be the same between the 2 camera (ACR is still BETA for 7D I think) but this will give you an idea about what the 7D can do against a 5D (it s a mark I btw not a mark II)

It seems to me 7D is not doing a bad job against the first 5D at least on pictures :)

I know this isn't video but it may give an idea about what the 7D sensor is capable of.

 
Some stuff shot at night with neon lights in high ISO.



Tweaked the curves a bit in color to get more detail in dark areas and get a bit more detail back in the skies. All pretty quick and dirty.

In case the video doesn't show up, here is the link:
