Does the DOF change when you zoom in on a cr2?
yeah well let me think about it...
we talking about framing the scene isnt it?
so lets say i shoot a person head
my depth of field is like from his nose to his ear
that is shallow one.
now if we zoom in in cr2 we get what?
head is choped half and we need to reframe it
when we reframe it what happens?
depth of field is not narrow anymore
now my depth of field is whole head and much more
not as shallow as it was when i frame just nose and ear
why is that?
because crop mode means 50 mm becomes 250 mm
now i have to shoot from distance not 4 meters but like 20 meters to get kinda same framing
and 20 meters gives me what? huge fat bulky depth of field that i can even bring a bus into it
p.s. of coz u dont get head shot on 50 mm from 4 meters
but u got the point
