(The reason the video is so different is because the 5Dmk2 live view was not set to movie display mode, so even despite the fact that the camera was set manually, the movie was still in auto. Thanks canon for options.So, it was user error. ) Here is another test showing the difference in ultra low light preformance between the 5dm2 and the d7k.

this is for those that may not have access to these cameras, but want to know basically how they react to these conditions, and how they may differ.

(NOTE: I would like to say that both cameras should be exposed the same, since the settings are the same. I will look into why this D7000 seems to be so dark.)

Did you do these tests?....or you just posting it here, and someone else did it? I'd like more information about the experience of the shooter. Interesting test.
 
Wouldn't a better test be to match the exposure levels by controlling the ISO and then comparing the noise levels in the images? Camera manufacturers label their ISO ratings inconsistently.

Maybe that is a good idea. I will do that, however for this test, I just wanted to see how much more light a full frame sensor would get, over a crop sensor, and didn't think about the noise quality. I think the 5D still had less noise, and was getting more light, anyway.

In another shoot I was doing, I was shooting the D7000 next to the Sony EX1 (original), and found that I had to bump the ISO on the D7000 up to 800 to get similar exposure, while the EX1 was at -3db gain. Both cameras were set the same in other settings: f8, 1/48, 24p

So, I assume the EX1 is amped up even at base levels. I have noticed noise in the EX1 at base gain, something I don't see so apparently on a dslr at < ISO200 .

(EDIT: After doing these side by sides, I am wondering if the D7000 I have is under exposing, or if there is a hidden function working against it. I'll look more into this and update)

That was my first time handling a 5D, and it took a while to get used to, but a few minutes later and I felt real comfortable. I like the grip of the 5D better. The D7000 is lighter, and i like that.

The 5D was too orange in auto white balance for my taste. That said, I would never use auto white balance, in general. So, until I get out in the day light with both cameras, I can't say much about the color rendering between the two. Perhaps, this saturday I'll have some time to finally do some proper comparisons.

Vitaly posted this over in the GH1 forums....

http://www.luminous-landscape.com/essays/an_open_letter_to_the_major_camera_manufacturers.shtml

Might explain it.
 
I just read that article and was about to post it! :thumbup:


I have noticed the D7000 being less exposed with both manual and dx auto lenses than others, so now that I am aware of the issue, I will try to do some tests to find the degree of the issue and see if others get the same results.


(further news, I had a blue pixel show up smack dab in the middle of my sensor at ISO800 last night. Any second thoughts I had about returning it are now gone.)
 
I don´t know what´s going on with that test.
With the same lens, the 5D ISOs are always 1-1/2 stop darker than Nikon´s. I´ve seen this also with the d90 and the 40 and 50D.

Sorry, but I'm not sure I understand exactly what you mean. Are you saying that your experience is the absolute opposite of what this test shows and that the Nikon cameras usually produce brighter images than the Canons at the same ISO?
 
Correct. My experience and the tests i shot last week with a D7000 vs 5D prove the opposite. Also previous test D90 vs 5D showed the same behaviour. Nikons were always "faster". Temperature? Date of manufacturing? Lenses?
 
macgregor

have you tested the HDMI out of this camera with a monitor like the SmallHD ?

decent RES ?

Do you get the horizon helper ?

have you been using with ring free modern nikkors, how annoying is that - is it true you must disengage LV to change the ap ?

I tested it with the Marshall 5" monitor yesterday. Seems to work quite well. Resolution is good enough for focusing. The only bummer is that the video image does not fill the whole monitor side-to-side. It's reduced maybe 10% to allow room for all of the data displays.

And yes it is true that in manual mode you must leave live view to change the aperture. But you can pre-set the aperture and then dial in the ISO while in manual live view mode.
 
you can focus with a 5 inch marshall (while rolling?)

have you ever tried a 7d and smallHD, more res

i just I cant focus on a 480p monitor / 5d combo

With all due respect, this is not a test of the cameras but of the user. Please find an explanation for this anamoly and report back to us.
 
Simple maths more like, when one is monitoring at 480 and recording at 1080 one only has approx 25% of the pixels that one is recording to evaluate, no user can guess information however skilled, some users however may be looking for a smaller Circle of confusion than others to be defined by them as 'acceptable focus'

The 5d is well known to be hard to get critial focus while rolliing when using a monitor due to its pisspoor HDMI feed, the 7d is significantly better, where does the nikon stand?

Of course the difference between the 5d and 7d are invisible on a 480p (http://www.lcdracks.com/monitors/V-LCD50-HDMI.html) monitor which will only show you 1/4 of a 1080 pixel capture whatever res is fed out by the HDMI of the camera

Imo such a monitor is no better than the onboard screen, for evaluating focus although it obviously has other pros like viewing distance and angle

Of course 'proper' video cameras, have a way of cicumventing a low res monitor, the ability to zoom into a portion of the shot while rolling (sony EX1)

I can confirm that the 5D does expose a tad darker at the same settings as the Nikon.

(ignore the cut off at the end of the video, the guy editing didn't set an output on the time line.)


Also, the issue with the original clip was that the 5D live mode had not been set to movie preview, and was auto exposing despite the fact that the camera was in manual mode.
 
peaking is your friend, a monitor that has it works even at very low res. i sometimes use an old b&w vhs viewfinder for that, it probably has a hundred lines or so but the peaking shows very clearly what's sharp. i would also argue that with the short dof of slr's it's easier to judge focus, there simply isn't such a thing as soft focus that looks sharp, a common problem with traditional video cameras, it's either popped into focus or a complete blur.

The 5D had not had its live view set to 'movie preview', so it was auto exposing. The 5D has a few different live view modes.

If the live view mode is set wrong, even when the camera is set to manual, the live view will override it and go automatic.

That is what happened in the video. the 5D was auto exposing. The 5D had been set first, and then matched the D7000 to those settings. So, the 5D was well exposed.

I disagree with you, and also am a fan of the camera generated peaking on the EX1, but its not a debate for this thread,

I just want to know what the D7000 is pushing out of its HDMI, each user can evaluate this information as they will :)
