Amazed at the 5D2 video's bokeh

I love the way the FF sensor melts the BG and FG into sweet bokeh when filming wild birds in busy environment using long lenses.

Here's a Pied Fantail filmed under a tree canopy in very low light:

At around 55 seconds, are those ants climbing up and down the tree?

That is beautiful video. Another item added to my long list of wants that wont ever happen.

Thanks, Bendel ..... you're right, those are out-of-focus ants walking along a back-lit branch in the background.

where did you get the audio for that video?

bokeh is primarily a function of the blades in the lense, not the sensor size.

nice clip.

But sensor size has a lot to do with DOF at any give aperture which would effect the amount (but not necessarily the quality) of the bokeh correct?

cool video parekoy...lol

yes, dof could be a factor.

You sir, are correct!

Wow !! Superb quality, I am impressed !

Yup. Try this with say an HV30 and see if you have the same shallow amount of DOF. Not going to happen as narrow as this.

dof and bokeh are not the same thing... you don't need 1.2 glass for good bokeh:

The shape of the aperture has a great influence on the subjective quality of bokeh. When a lens is stopped down to *something other than its maximum aperture size* (minimum f-number), out-of-focus points are blurred into the polygonal shape of the aperture rather than perfect circles. This is most apparent when a lens produces undesirable, hard-edged bokeh, therefore some lenses have aperture blades with curved edges to make the aperture more closely approximate a circle rather than a polygon. Lens designers can also increase the number of blades to achieve the same effect. Traditional "Portrait" lenses, such as the "fast" 85mm focal length models for 35mm cameras often feature almost circular aperture diaphragms, as is the case with Canon's EF 85mm f/1.2L II lens and Nikon's 85mm f/1.4D, and are generally considered exceptional performers. A catadioptric telephoto lens displays bokehs resembling doughnuts, because its secondary mirror blocks the central part of the aperture opening.

here are a couple of bokeh shots at 5.6, from crop sensor cameras:

true and false. sensor/image size is important, but DOF is really a factor of the focal distance, aperture size, image distance (distance between the nodal point of the lens to the image plane) and object distance. You can have similar DOF with a FF image compared to a crop sensor as long as the lens, aperture, object distance and the image distance is the same. It's just that you are cropping out a portion of the image in the camera. It's very similar when shifting an image with a large format camera. Your DOF remains the same, you are just moving the crop.

Bokeh is dependent on the aperture size, aperture construction and even the lens design.
