DOF equivalence DX-FX
6 months ago

I've been wondering about the depth of field equivalence between DX and FX cameras at a given aperture. Let's say you are shooting a portrait indoors with a FX camera and a 50mm lens, at f2.8 in order to blur the background. Would I get the same result if I shoot al 35mm and f1.8 with a DX camera? And so, FX f5.6 would be (aproximadamente) about DX f3.5 or f4?

Thanks in advance and kind regards
