"5D (full sensor size) – even though it has larger sensor I find it only marginally more light sensitive."
LOL - what?!?
you seem to have some odd ideas about how cameras/optics work. this blog post should be deleted/removed until you back it up with some examples, cause as it stands this is nothing more than opinion.
- If it want as you say 98% of content on the internet should be deleted too.pr2
- so be it.********

for quack and other confused souls:
So even if the circle of confusion (the blurry stuff) are of the same size on 7D and 5D the view changes - namely on 7D it's more "zoomed in" when at the same focal lenght (here 70mm) so to get the same view we need to zoom out (to about 43mm in this case) at which point the circles of confusion get smaller - meaning 7D has more DOF.
- Good example,
would have been nice if you had focused on something in the mid ground so you could see the bokah behind the subject.tedvandell - the bokahtedvandell
- this example shows if you shrink the 7d to match its sensor size it matches the center of the 5d photoquack
- just like i said it wouldquack
- Good example,

As sensor size increases, the depth of field will decrease for a given aperture (when filling the frame with a subject of the same size and distance). This is because larger sensors require one to get closer to their subject, or to use a longer focal length in order to fill the frame with that subject. This means that one has to use progressively smaller aperture sizes in order to maintain the same depth of field on larger sensors. The following calculator predicts the required aperture and focal length in order to achieve the same depth of field (while maintaining perspective).
kindly fuck off

its position, not the sensor- Clearly the second sentence states sensor size is part of the equation.tedvandell

oh quack. you are so wrong and everyone else is so provably right, but you can't admit it even when citing the same facts as everyone else. i may not have 43 years of experience like ted, and as a photographer i'd say i have only ~3 years of pro experience (so less than your "experience"), but what everyone else says is true - bigger camera = shallower depth of field, from my own experience and from scientific basis. kindly start thinking coherently and rationally, or i shall i have to paste the child-camel internet argument pic in this thread.
you poor thing.
- Beautiful work on your site bigtrickagaintedvandell

regardless if quack is right or wrong the info that blog post is incomplete and needs proper examples to back up the claims.

Yeah but what about the 1D?
- the 1d has 1,3 crop, so in terms of DOF and FOV it sits between the 7D & 5DJurre

and the t2i?
- i would assume anything that goes for the 7d goes for the t2i also since they use the same sensorbigtrickagain

bigtrickagain, ive been asking around on this.
all signs point to position making the difference, not the sensor.
if you frame a crop sensor to match that of a full frame sensor the camera proximity to the subject and other back elements is different. so of course there will be differences in bokeh effect
however if you mount a lens then swap bodes, bokeh remains the same as the image becomes cropped because proximity has remained- You just don't know what your talking about. The number of pixel on the full frame sensor changes the Circle of Confusion.tedvandell
- Circle of Confusion. Just like it changes the magnification on lenses between full frame and 2/3 frame sensor.tedvandell

i'm glad you've backtracked enough to make some sense againbigtrickagain - wrong, as you're cropping to zoom basically and not getting the nice DOF of the actual focal length.inteliboy

but whateva, we don't pay or employ each other ;)

quack, how much more clearer i have to be? I show you the picks and you still don't get it?????

I know shit about photography, understand only part of what you're saying, but from my impartial point of view and from the images above, the diference that I see is just crop, everything else looks the pretty much the same.
- inteliboy0
^ Yes but, to get that focal length on a full frame you'd use a ~100mm, and therefore get an even more shallower DOF. It's fkng plain clear logic. To argue otherwise = do not know their shit.

i just want to say mind all my swearing, this is one of my favorite threads. there are several other threads like it on the internet that go into deeper detail regarding CoC, pixel density, as has been referred to and the Nikon D2X which can shoot in both full and crop mode which would be great for this dicussument ;)
i love arguing in one thread and agreeing in the other, been a long time since i've had this kinda fun here :D specifically you bta :P
- the only time anyone has behaved in such a love/hate manner with me before was a girl named valerie in 6th gradebigtrickagain
- she totally had a crush on me.bigtrickagain
- and what other thread are you referring to... the blog thread?bigtrickagain
- any other thread we usually laugh or seem top agree on most thingsquack

For fucks sake, just shoot some fucking pictures.

I was amazed that Lucasfilm uses the 5D mark II as a B camera already to intercut with the Sony F35 (used to shoot Star wars with: 150,000 dollars). It's quite a revolution, a 2,000 dollar game-changer :-)
They say on a big screen the images are indistinguishable.
