    Thanks so much, Chris! I am one of those who can never get it straight, so this will be a great touchstone.:drinks:

    As an addition to that article, I can wholeheartedly recommend this DPR article about aperture equivalence and its effect on both DOF control and noise performance:

    It goes a bit deeper than the above article, but you might find it very helpful in comparing the DOF and noise abilities of cameras with different sensor sizes based on their respective lenses' aperture / f-number.
