There is a consensus among some streamers that if you can't reach maximum view range with optics, crew skills, vents etc then you should pick binos instead. I now think that this is wrong.
I had been following that for a long time and was surprised how rarely I would ever get benefit from binoculars. You can't spot aggressively, you often get outspotted without getting having time for the binos to kick in and they suck for general late game yolo.
I even made the mistake of using binos on stuff like the Conway and Foch. As soon as I switched to optics everything went much better for me. Even stuff like the PZ V/IV seems to benefit way more from optics despite pitiful base view range.
Imo Binos are useless on most maps for most vehicles classes. They are obselete equipment with a few minor exceptions. Optics are almost always the better option even if you can't reach the maximum 445m view range.
