Canon EOS 7D (Hand Held)
This Footage is right out of the camera.
1280 X 720p
FPS: 59.94 (60p)
Data Rate: 45.45 Mbits/s
Day Time: 3:30 PM Temp 72 Degrees.
Lens: 28mm-135mm Canon (28mm) (IS Turned On).
Shutter Speed: 1/125th
No ND Filter.
CF Card: SanDisk Extreme 60MB/s UDMA 8GB
7D Factory Settings.
So what is the problem here? (No the 7D did not get hot and or overheat).
I shot the same place and time with other lenses and CF Cards:
I got the same results from a Tamron 28mm - 75mm Aperture 7.1 (No IS).
I got the same results from a Nikon AI 28mm Aperture 7ish, (EOS-Nikon adapter).
I got the same results from a SanDisk Extreme III 30MB/s 8GB CF Card.
I got the same results from a SanDisk Extreme IV 45MB/s 8GB CF Card.
First lets rule out the slow CF card myth that I hear every day, (From Canon Reps).
I have now tested SanDisk Extreme III, and Extreme IV, and Extreme 60MB/s CF Cards.
There are no visual differences at all that I can see. The data rate on all 3 cards writes the same from the 7D.
I tested 24p, 30p and 60p on each card. No Frame drops. No buffer overflow.
If you are a Pro Sports Still Photographer and need the fastest CF card for the 7D, anything over the Extreme IV 45MB/s is a waste of money.
I think I can also rule out the lenses as all three that I tried showed the exact same aliasing and moiré artifacts.
Maybe the 7D just does not like Sunday afternoons?
This is the third 7D I have used that looks like this in 60p mode, so it is not just a bad unit. (Not every 60p shot looks like this).
The reason I made this test in the first place was to test hand held a 7D with and with out Image Stabilization turned on.
The second reason was to test these three SanDisk CF cards to see if the Extreme III 30MB/s was fast enough to shoot video on the 7D with out any problems:
Test one results: Using a zoom lens with Image Stabilization turned on is a million times more steady hand held on the 7D than with out.
This is something everyone should think about before buying a zoom lens for your 7D.
Test two results: The 7D manual says use a CF Card at least 8MB/s for video (Pages 149 and 247). Canon Reps and many others say use something like the SanDisk Extreme IV 45MB/s CF Card, so I tested the SanDisk 30MB/s, the 45MB/s and the 60MB/s CF Cards. I can not see any difference.
If you are shooting video only on the 5D MKII or 7D the 30MB/s cards work fine on my tests. If you do not agree please explain what your own tests show.
I also shot some nice 24p footage today on the 7D. I WASTED lots of time trying to avoid things that would show aliasing. I see no reason to bore everyone with my 24p 7D footage as it has no local disturbing looking people chain smoking in it. That seems to be the new litmus test for cool 7D footage.
Conclusion: I still think the $1700 body only 1.6 crop Canon 7D is a crap sandwich. If you use really fast expensive Canon glass and 0.8 - 0.9 ND filters you could get some nice 24p video shots out of the 7D as long as you keep the aperture wide open, the ISO low (As in 100 – 400 ISO) and use plenty of light.
PS. Feel free to comment on the footage and or my test results. I no longer care but others that actually like the 7D may still want to find ways to work around this 60p mess.
This page is to show some problems in the 60p footage and maybe some of you can help each other work around them.
I put my CF Card Speed tests up here because I have looked all over the Blogs and Forums for months and found nothing but bullshit information from people about CF Cards.
I hope this information helps.
Here is a link to my 7D/5DMKII/GH1 rant page on Vimeo so we don't repeat ourselves:
Somebody shoot a "Nocturne" type short with the 7D like Stu Maschwitz and Vincent Laforet did and then I will stop calling the 7D a crap sandwich.
