Magic Lantern adds 3x multiplier (zoom) to RAW video for the Canon EOS 5D Mark III

by planetMitch1 Comment

We saw this on the Magic Lantern pages:

This is now possible and it equivalent to putting a 3X multiplier on your lens without changing the f stop.

Note that this is currently very very very alpha and if you read the post, you'll see the process is difficult to even set up and execute – but that will possibly change as the Magic Lantern team has time to code improvements if this process is deemed something to add to the setup.

Also note:

Technical Issues: So far I am unable to control shutter speed and aperture in RAW video mode. I think shutter speed is 1/24 for 24 fps and the aperture is always WIDE OPEN!

So for now, this is very early in development and may not end up being a feature of Magic Lantern but it is astounding to see what is going on with these cameras with the Magic Lantern software!

The beauty of this video is that there is ZERO loss of detail when compared to a photo taken a full resolution. Of course the photo covers the entire size of the sensor 5760×3840 pix while the video is just a small portion of the sensor in my case I am generating a video of 1920×1080 pix. There is no down-sampling of the sensor so the image is a 1:1 crop.

Since we are using 1920 pix out of the 5760 pix (width) the zoom factor is 5760/1920 = 3X.

The process to record this is a bit arduous, but again, hopefully this will be improved in future versions.



Samples and description

Ok, so now that you're possibly totally confused, I asked @RenatoPhoto who posted the thread on the Magic Lantern forums if it would be possible to share some photos showing the setup so it would be a bit more clear and he sent these to us.

First, a normal view:

Now, ‘zoomed'

So you can see the detail that is there in the zoomed video!

And just to go back and compare H.264 video to the new DNG RAW, @RenatoPhoto provided this image:
