Last weekend, I did a few test shots on a new location I was exploring with my friend Robert and we took the time to do some 7D vs 5D tests. Most of our conclusions can be read in the previous post on the subject.

Here is the video of the moire pattern test we did. Most camera would have had some issues with all the overlapping vertical bars but the 7D handled it surprisingly well.

Note: this was our first test with the 7D on the Glidecam and, while it was balanced, it was not heavy enough. We have corrected the issue since by adding some serious weigth.

I have a 5D vs 7D clip coming soon. Both taken at the same EFL, something no one seem to have done yet!

We shot a few clips yesterday with a 16-35L mounted on a 7D to compare it with the 5DMrkII with a 24-70L. I dont have the clip in my hands yet (will get them tomorrow), but from our initial tests, it seems like the 7D low light capabilities at higher ISO is about 1 1/3-1 2/3 stop lower than the 5D. Basically, ISO 1250 on the 7D looks about the same as 3200 on the 5D.

The increase of noise is not linear. By that I mean that ISO 800 on both camera is about the same, it is only above 1250 that we can see a difference.

Scott Boune who did his own mini review of the video of the 7D does not seem to notice the difference between the two. It is probably because he did not go high enough in the ISO chart.

Is this something you should worry about? No. Unless you are shooting in very dark places (or at night @ f2.8 and smaller), ISO 640 should be enough for most shots. Also, to correct Scott, the 5DMrkII also has the auto focus feature for video and it works the same way as with the 7D: it only works in live view: while you are not recording.

Our tests also show something very interesting: the 7D seems to process moire pattern much better than the 5D and the jelly effect is much less noticeable. This is probably thanks to the 7D smaller sensor, being smaller, it takes less time to fully scan it. What ever the reason, it makes the 7D much more desirable for fast moving subjects.

As I said above, I will get the footage from this weekend tomorrow and should be able to put it online soon.

We also did some steadicam shots at 60p, I am very curious to see how these will turn out, especially since I am the model walking around like an idiot…

I will have access to a 7D this weekend. I already planned a few tests to compare it to the 5DMrkII. Anyone has an idea of a specific test you want me to perform?

Just saw this 7D Field Review on CanonRumors.

While the guy is a photographer and approach the product from this perspective, it is interesting to see how well the camera was performing. He even goes as far as saying that it could replace his 1DMrkIII!

Lots of screenshots, go take a look.
