A person leaves their, my, house with specific gear,, thats fixed info.. the dragonfly proportions , again , are a fairly fixed parameter.  I can alter my distance I can alter the light , I can alter all the settings on the camera.,, none of that is fixed , and so thats really what a person needs to know to get the maximum resolution out of the gear-- is how far they need to be from the thing and what aperture they need to use, with which focal length ( on a zoom). Ballparking your technique , youre not really optimizing what the camera can do. If I zoom back to 70mm maybe that diffraction thing stars affecting my resolution , but if Im out at 300mm then I start getting away from the sharpest resolution of the lens ,, but that still may be better than the diffraction. If I close up my aperture , then I start to gain DOF , If I open my aperture , then I will need to back up to get the Dof again,, but if I back up , then I start start having a smaller image, .. and so forth. My point is however , that the optics should be able to be calculated and optimized ,, knowing the depth of the field one needs crisp clear,, and that will be particular for any given lens. If One cannot actually know this information , then data about the airy disk and such , while very interesting , doesnt actually help more than to chimp the shot.And this doesnt just apply to bugs , it would hold true for other things like product placement shots etc.</blockquote>
