I give you, if you don't understand this simple concept then go ahead, live your life believing that the world is flat.

feedback loop going on here...

true hans, however in order to equally match the too cameras, or planes a 7d will require wider lenses.
all in all a 5d or full frame camera will give you the most range out of your glass, considering that the ef line was built for 35mm planes

omg, wtf, ffs, etc
it's the lens that makes the difference not the camera...
a wide angle lens has a greater depth of field than a telephoto lens.
so naturally if you use a wider angle lens on the 7D to get the same crop, more of the image will be in focus than the 70mm on the 5D. But that's the lens, not the camera creating this. As you say yourself, the DOF of the 70mm lens is the same when mounted on the 7D or the 5D, but the FOV is reduced on the 7D.
So it's ridiculous to say that the 7D has greater DOF. It has a smaller sensor, so requires wider lenses to achieve the same field of view, and it's these wider lenses that give a greater DOF. The camera itself is just a sensor plane.

Now can you make the blurry circles with 7D as large as 5D? - Yes, you would have to move the camera further back, but let say if there was a wall behind you and you couldn't... Then you would have to be stuck with 7D's lesser DOF.

I can't comprehend that even with pictures there are some people who still don't get it... So here is a clear, I hope, explanation:
If i put 70mm lens on 5D and 70mm on 7D i'll get the same circles of blurriness within the frame:
But as you can see with 7D i'll see significantly less. Because of the cropped sensor, to get the same exact frame with 7D as with 5D, i would have to use 43mm lens on 7D to see what 70mm lens is seeing on 5D.
So if you compare the blurry circles of 5D with 70mm lens:
and 7D with 43mm lens (the focal length that matches the 5D's 70mm):You can clearly see that the blurry circles are larger with 5D then 7D... Thus 5D has shallower DOF.

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.

For fucks sake, just shoot some fucking pictures.

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

^ 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.

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

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

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