Re: [Avid-L2] New Nikon D3

I disagree, Rick.

The only reason the Canon - and other large sensor cameras - look as
good as they do is because of their large raster size.

We just played through this discussion a week ago, with me
accidentally mixing up large depth of field with small depth of field.

The bigger you image sensor, the less your depth of field, which is
what makes a lot of images very appealing. Small-sensor prosumer
cameras, like my DVX100a, have a sensor that may well be more than
adequate to capture HD images on a pixel for pixel basis, but the size
of the sensor means that depth of field is very large. That's nice for
keeping everything in focus at all times, but not so nice when you
want a beautiful SMALL depth of field with the background thrown out
of focus and gorgeous bokeh in the lights in the background.

So, yes, you DO need a full frame sensor.

Even the 7D "magnifies" the focal length of a regular lens over the
way it's "supposed" to look on a full sensor or 35mm film. I don't
remember the ratio, but on a 5D, a 50mm lens looks like a real 50mm
lens is supposed to and on a 7D it looks more like a 70mm lens.

I don't have any idea how much the sensor size between the 5D and the
7D changes the actual look of the depth of field. I'd love to see some
pretty shot with out of focus lights in the background shot with the
same lens on the 5D and the 7D from the same position. The 7D would
look closer and have more depth of field (I almost typed "less"
again). But by how much?

I also don't think the 7D has the same light sensitivity as the 5D. In
addition to more pixels on the 5D sensor, I think the pixels (or
whatever the light sensing units are called) are actually LARGER,
allowing them to gather light better, increasing their sensitivity and
lowering noise.
