Message: <blockquote data-quote="henry link" data-source="post: 3426764" data-attributes="member: 6806">"CHROMATIC ABERRATION (10 points) - The chromatic aberration is estimated by our own observations, setting a contrastive object in the center of the field of view and moving it to the corner. Depending on our observations, binoculars can get here from 0 to 8 points for the center performance and -/+ 2 points for behavior at the egde."The above is a quote from the Allbino's article "How do we test binoculars?"Does that subjective method look reliable or repeatable, especially for more than one observer? Notice that one binocular could score an 8 for the center and a -2 for the edge for a total score of 6. Another could score a 4 for center and a +2 for the edge for a total score of 6. Which would you prefer?</blockquote>
