Running and sprinting with binoculars in hand is stupidly fast and drains very little stamina.
This is extremely unrealistic, considering that you are still carrying all the weight of all your gear, and that there is no way to do it without a binocular.
The excuse of "but you don't have a weapon in hand" does not apply - If it was the real reason, we should have been able to do it without needing to own a pair of binoculars.
Handguns have a similar issue, but to a lesser degree.
Please fix the animations and the stamina drain that is associated with them.
