Давно не брал я в руки камеру...
Помнится, копья о происхождении разрешения 1080р-60 ломали очень долго.
Камрад Nutsey (GoPrawn) в логах показал что к чему:

Принудительно прописал сканирование с площади 1920х1080р для этого режима.
Правда "бонусом" проявился кроп-фактор со смещением центра кадра.
Но зато теперь 60 кадров даже чётче, чем при 30-ти кадрах в FullHD.
Изучаю далее на предмет смещения центра области сканирования...
