[QUOTE="J-see, post: 467703, member: 31330"] Your sensor pixel is between 4 and 5 micron for most cams. You'd not even see 1µ in a shot. Sharp that is. With a crop sensor you'd need f/1.2 at 50:1 to have a DoF of 1µ, 9:1 for 6.2µ Also keep in mind macro magnifies which is why we see stuff usually too small for our eyes to notice. It doesn't imply it is sharp or that the DoF is minuscule. Btw, usually we prefer a large DoF so I don't even understand why he'd require one the size of 0.1µ. [/QUOTE]
