So I'm proving myself wrong here but I quickly shot off a bunch of pics of my cap. Starting at 2.8 and going to f 22

OK I hate to dredge up this debate again. But after continued research. This is what I have uncovered.
with increased magnification depth of field becomes narrower and narrower. Meaning a typical photo the the subject in the image is much smaller than what it's actual size is. like a landscape photo. You could have a depth of field from 3m to infinity at f 22 Now take the images above at nearing 1:1 size ratio the max depth of field becomes very narrow. to with in 20cm to 25cm. If we had the ability with this camera to increase the magnification to 2:1 or even 4:1 we would find the range of depth of field would become even narrower Jason

Go
Jason,
I'm sure that is the case as the closer you get the less amount of DOF due to the size of the image taking up the whole frame. Please read my previous post. DOF only exist if you can see the difference in distance when you are taking the photo. The debate that you did not agree with, was that the lens aperature setting DID NOT make a difference in the DOF. I am right in telling you that it does and YOUR photo trial proved the theory. So I hope that we can now come to a final conclusion that DOF is affected by the cameras/lens aperature setting. This you have proven yourself. ________ GN125 Last edited by Gooly001; 01-25-2011 at 05:02 AM.

Yes Aperature effects DOF but Max DOF is limited to magnification. Look at my last pick at f22 Dof is very shallow.
you can see out of focus in front and behind the field of focus J
