Occasionally we see such comments on the BF that require a small correction: the ER of the binos is a fixed parameter that does not vary with the length of the eyecups.
Of course the ER is a "fixed parameter" but see your post #111.
I was responding to your allegation that it looked to you that "it looks like it might be a design flaw if too short eye cups are the reason for getting blackouts." (By the way, your statement is hardly an accusation.) I simply pointed out in response that the eye cups on the Monarch HG had longer eye relief than the Monarch 7 did.
Incidentally, how many complaints have there been on BF about getting blackouts while using the new Monarch HG 30mm?
Binocular manufacturers have made mistakes in the past and put eye cups on a binocular that did not fit its stated eye relief. There isn't enough evidence that this is a problem yet with these binoculars.
