Not the most technically accurate but I did a rough side by side last night using various lenses and frame rates.

Thx - a good side by side test. It deserves the name. At first glance - the 7D wins... ;-)

Capice, i was going to say the same thing but I held my tounge (typing fingers). Maybe there were just some soft focus shots with the 5Dll.

... Maybe there were just some soft focus shots with the 5Dll.

Right, but to my eyes the aliasing is more obvious in the 5DII footage. At the moment im unfortunately a bit fixated on it...

Ha ha...me too. But I think i know why....take notice of the 5Dll's frame... The camera is moving which I think further exagerates the aliasing effect. The 7D looks still in most shots. But regardless it does appear to be slightly more of an issue in the 5D.

I shot charts that demonstrated both cameras being identical. Were the picture styles for the 5d and 7d the same?

PS - I want the answer to be yes so that my tests are proven wrong.

And once again, true :-).

This video is worthless to judge aliasing. It's quite obvious the both images were downscaled in an NLE using a "fast" filter.

Otherwise, thanks for the test! You get high points for not shooting flowers, cats or people in the street at night.

Regardless of "how' they were downscaled in post it still puts them on an even "real world" type of playing field. It's not scientific...but it definitely helps.

tbh there really is no point in doing a comparison if both cameras are not subject to the same conditions. The 7D clearly is on a tripod and the 5D was on a monopod. You cant help but be disturbed by the aliasing in both but particularly the 5D which of coarse is exaggerated by the non steady frame.

Thanks for the test though, it does show the depth of colors and some other stuff :)

Again, this was not a scientific test (no charts, etc.), but the 5D was mounted to the top of the 7D for our skew test, and the other tests were as consistent as we could manage (both cameras on tripods, same relative focal length/framing, same exposure, etc.).

I believe they were both at Standard.

They look identical to me judging from the Vimeo video in terms of dynamic range, quality, and codec.

I wouldn't put 30P next to 24P, You're hurting the cadence of the 24P video by doing so.

Why is 7D footage lagging? 5D footage is smooth but 7D seems to have some problems. You can notice it well if you watch the cars.
