К разговору о ТЭС (Теории Эквивалентной Светосилы) — пример на 250см дистанция
Да, и правда шумы приведены одинаковы, глубина резкости, согласен, картинки просто не отличить (на одной камере с одной точки 50мм и 100мм. Правда, в оригинальных размерах на 100мм можно заметить шумы, они чуть заметней, но при уменьшении размера 100мм до угла 50мм той же части изображения получается на удивление всё одинакого.
