martinangus Posted May 17, 2011 Share Posted May 17, 2011 <p>I just did a test to understand how my 50mm 1.4D Nikon lens behaves for sharpness at different apertures.<br />I have been wrestling with how to achieve those super crisp images - without much luck despite using a tripod and timer.<br />I was under the impression that smaller aperture was directly related to crisp focus. My tests this evening prove that wrong. I have discovered "diffraction" and its' negative effect on focus at the aperture gets smaller.<br />Here are my images.</p> Link to comment Share on other sites More sharing options...
