damn nice DoF
I agree...
I have always been confused about DoF... Some sites on the internet claim it is affected by distance to subject, aperature and focal length. While others claim that focal length has no effect, like
this one that actually demonstrates it.
Anyone know which is correct?
Sensor size, distance to subject, aperture all effect DOF.
Sensor size shouldn't really affect DOF. It affects the lens factor. For example, 1.6x on the Canon 300D. It's essentially cropping. Optically, it's not a true magnification. The lenses aren't stopping down or anything to direct all the incoming light onto a smaller surface...unless we're talking about ef-s lenses, and then I don't really know if that's an issue or not.
But focal length, distance to subject and aperture do all affect DOF.
edit: Well, actually, I don't know if focal length actually affects DOF. But it does affect perspective, which can certainly
seem to affect DOF.
