à ouverture relative égale.>
Un 28mm à f2 sur 60 Mpx, recadré à moitié donnera exactement la même
image et la même profondeur de champ qu'un 56mm à f4 sur 15 Mpx. Bien
sûr f4 c'est pas f2 au niveau de la pdc et on n'aura jamais le flou
obtenu avec un 50mm f2 sur un capteur de 15 Mpx.
J'ai déjà beaucoup de peine à comprendre mes propres explications,
alors, les tiennes...
Peux-tu reformuler ?
