Surely if the pixel count is higher, the resolution is better so the DoF is apparently better? :-B Note the use of the word apparently because none of us is measuring, only looking.
Something is wrong here .... We are mistaking overall blurriness / bluntness with shallow DoF !! :-*
...DoF is the area of acceptable sharpness....high Mp sensor plus high quality lens and use of lowest ISO give you best sharpness, then that will allow you to see the Dof more clearly...
There is no mistake. DoF is the area of acceptable sharpness. If a high Mp sensor plus high quality lens and use of lowest ISO give you best sharpness, then that will allow you to see the Dof more clearly - the inverse will add it's own blur to the existing blur and narrow the apparent DoF.
Sensor size does not affect the DoF at all. You will get the same dof if you use a 85 mm lens at f/5.6 from a given distance on DX format or on 8x10'. What does change is the field of view of course. If you take the field of view as a constant (e.g. a head shot portrait) you either need to change the focal length if you want to keep the distance or you need to change the distance if you want to keep the focal length. And this will impact the DoF.
No, it isn't. The depth of field is strictly relevant to the size of the aperture opening and to the specific focal arrangement, and also to the size of the sensor or film being use. You guys are just confusing the matter for some reason.
