[QUOTE="Stoshowicz, post: 426899, member: 31397"] Is there a best sensor size optimizing DOF vs the noise inherent in the smaller sensors? I am under the impression that (depending on the depth of ones subject) a micro sized sensor can at least achieve focus covering the subject , as opposed to having to focus stack everything bigger than an ant. Light becomes the issue more so, when one clamps down the aperture to get the needed dof. If you have the DOF you need because of the smaller sensor size resulting in less actual magnification , then perhaps the noise advantage with lower ISOs of an FX isnt there. Since you end up increasing the ISO youd employ to counter it. I dunno. Comparing the photos of cameras using the same ISO but different capacity sensors without considering that one increases the number of photons per unit of resolution to fill the larger photosites isnt fair comparison. So Im thinking maybe the only way really to determine whats the best tradeoff is to have employed different systems , and then just blurt out a specific one rather than generalize, but I'm not sure.
