So you are basically saying that a binocular with a larger PFOV (perceived field of view?) but a smaller apparent field of view provides a sense of transparency via larger oculars? The collapsed eyecup part has me a little confused. The setting for the eyecups varies from person to person. Some folks cannot collapse the eyecups completely because it provides too much eye relief which leads to blackouts and/or a form of tunnelvision. The larger ocular part I understand as I often find myself leaning towards binoculars that do have larger oculars for a variety of reasons.Do have a particular model(s) in mind so thought I can relate to what you are describing?</blockquote>
