Futurama is somewhat right. Same focal length at same aperture taken with a FF and a APS-C. The FF's DoF is thinner.

Lols.

This topic is so win.. Haha...

thats because you have to move backwards to frame it the same way with same focal length on smaller sensor than on full frame. since the focus distance changes, the dof changes. its not about f-number, its about change in focus distance. if the distance is same, it makes the crop different, so if you crop the picture, but the crop factor of the smaller sensor, the dof will be the same. also when you focus closer(to frame same on larger sensor than on crop sensor) the focused area changes to blur faster, this is why full frame(, medium or large format) gives different type of dof to small sensors.

Well according to the reviews on the Olympus Zuiko 14-35 f2.0 the DOF created by a similar f2.8 zoom on a 35mm camera is still shallower.
I am sure there are numbers and comparison out there but I couldn't find it
but what you said kind of make sense
so I guess it means in order to get the same DOF as a larger sensor camera the smaller sensor has to use either a larger aperture or shorter focal length or a combination of both to achieve the same DOF. Right?
ffs this gives me headache

yes, but the dof will still look different. and with larger sensor you need to use longer focal length to get the same fov, longer focal length causes the focused area to turn to deeper bokeh faster

hmm do you mean that longer focal length causes the focused area to shrink because focal length, aperture and distance to the focused subject are the main factors. The longer focal length the shallower the DOF would be and
the closer to the subject the shallower the DOF would be as well so it means if you want to get the same FOV with a 35mm sensor you would either use a longer focal length or get closer to the subject which means the DOF would
be shallower. Right?
Well at least that's what I have learned so far and other than that a 35mm camera also seems to be much better for landscape photography as well
which is why I just ordered a brand new 5D mk2 about five minutes ago Now all I have to do is wait.....

ARGGHHHH



I'm sad now

But gratz anyway

haha don't be sad. Unlike you I don't even have any lighting equipment all I have is some crappy 430EXII flash which I have only used like five times since I bought it
but thanks
