Dumb Question regarding DOF

[Chillimonster]

Does pixel density affect Depth Of Field, in the same way that Sensor size does (and how does that work as well!)

Having a bad time getting my head around it :bang::bang:

Can't see how it should but I am always open to learn...

BTW how does sensor size affect DOF?

The only dumb question is the one you don't ask.

All to do with circles of confusion

or so i am told.

A plain english explanation would certainly help (with piccies if possible )

The smaller the pixel size the more visible any loss of sharpness will be when viewed close up. So, this implies a smaller depth of field - but for practical purposes this shouldn't matter much between similar sensor sizes.

All else being equal, longer focal lengths produce a shorter depth of field. A 35mm on APS-C is approximately equal in field of view to a 50mm on full frame, but will give a greater depth of field.

If the aperture is the same, the smaller the sensor (film neg) the greater the DoF, which is why many take great close-ups & macros on small point & shoots

MF on the other hand would be pretty useless for macro work as the DOF at the same aperture as a FF/cropped DSLR is much less
