[QUOTE="Eyelight, post: 363313, member: 24753"] If we stop and think about the images we take and the ones that are in the box (throw back from Kodachrome), there are not that many that diffraction is going to impact. Here is why. Sharpness is relative to blur. There are images with blurry subjects that look great because the background is blurrier. There are very few images that every single square nanometer is perfectly sharp, so we are fine with blur and use it every day to our advantage. One other reason, is the only focused part of an image is the focal plane. The DOF in front and behind the focal plane is falling off immediate; just doesn't get unacceptably sharp til the front and back edge of the DOF, which is arbitrary depending on what you plan to do with an image. However, good to understand the things that impact every aspect of what I'm trying to do. Good discussion. Good questions and replies. [/QUOTE]
