Canon 5D crucial movie settings

In my previous post I've shown the worst of 5D video performance

I've playing around a bit and managed to get better results.

1. It is crucial to turn off highlight priority.

2. Non Canon lens are better. Using my Canon 85mmL1.2 I had several problems, including Color Aberration and the Canon 5D video mode selecting F16 and pushing ISO to 2000!

So I attached a Leica lens with adapter. Not only are the images stunning but I have control over aperture. I kept it wide open at 2.0 and the camera was forced to select low ISO. Occasionally it tried selecting faster shutter speed and still push ISO high, but there seems to be a cap to that stupid priority.

I don't see this as being a viable professional video solution, and for some reason I still have the feeling I'm playing with a cell phone video camera, just higher resolution.

I don't know why the auto controls would up the iso before it opens the aperture that sounds strange to me. Perhaps you werent using a constant aperture lens and you were zoomed in?

Either way, we know the 5D is amazing camera in low light. Reverie proved that. You just need to come up with altenative ways to trick the camera to get the settings you want. and you want to use fast lenses (not f4 lenses)which is one of the main reasons this camera is so great, you have the ability to use the super fast canon lenses with video.

The full frame sensor, lenses and clean high ISO rating have all the makings for best camera for low light thats out there. You just need to control the camera and not let the camera control you.

For instance, you can use your 85 1.2L. Put a tape or something that will block the contacts of the lens so that the camera is forced to you the aperture wide open. It will then adjust the shutter speed and ISO accordingly. Reverie was mostly shot at 1600,2000 and 3200 ISO, did that look noisy to you? You also have to remember that the grain will look much better with video because you are taking an image from a 21 MP sensor and cramming it into HD resolution.

I agree you cant be 100% consistent with shutter speed, aperture and ISO but you trick the camera to getting close to what you want. The fat32 4GB limitation makes it useless as an event video camera but these are all things that hopefully canon will address, making this an amazing tool for video.

I don't know how the camera decides to change exposure. I only used L series lens, one 24-105 L 4.0 constant, and a prime 85mm L 1.2 which my camera refuses to use for film at less than 4.0.

The camera is great in low light but you have to trick it. And reverie was not really shot in low light. I managed to find a work around but it's annoying.

I found a perfect solution, I use my Leica lens on the 5D and the camera can't touch the mechanical aperture. The video is amazing now and I'm very happy.

As for the full frame sensor, yes it's beautiful with my lens but I suspect that the camera does not use all the pixels. It's very task intensive to scale down from full resolution to HD size 30 times a second. I think they use every third pixel, and that would explain the occasional aliasing problems.
