I agree. A complete grasp of the math is not necessary, especially since we should be concentrating on only one sensor size or film format at a time.
A general familiarity with DOF is sufficient and spending too much time on the minutia does not make your pictures any better - it just slows you down.
Comparing film or sensor formats is a mental exercise that only a few of use might enjoy and it does not improve anyone's photography.
In other words you spend a whole bunch of time defending a theory on COC and then say it's minutia and forget about it.
Would of it been easier to say it's there but you cannot notice it. The last thing I worry about is COC when I take a shot, I have other things on my mind. All I care about is hyperfocal distance and DOF depending on what I want to do about it. Then shoot it about a 100 times cause I still didn't get what I wanted. Crap If I am shooting a bird in flight I am lucky to get it in the frame and on the correct side. Then we worry about focus, shutter speed, ISO, and aperture. I just can't think that fast LOL.

Q #1: Pixel count and sensor size are not related.
Q #2: DoF is a function of lens aperture, having nothing to do with sensor size.
#1- aren't pixel count and sensor size both involved in resolution? ( or should I have said "definition" to describe the detail present in the photo at full size.)
If not, what determines the detail in a photo?
I certainly have noticed that the 8 mp photos of my iphone don't have nearly 80% the quality of my 10 mp crop DSLR.
#2- is it just me or does depth of field not appear shallower on a full frame?
Q #1: Pixel count and sensor size are not related.... (
show quote)
#1 If I have a 18 Mp crop sensor and a 18 Mp full frame sensor, as Hillary would say "What difference does it make"
The difference is pixel size. Yes size does matter. For clarity, lets use the bucket analogy, and substitute buckets for pixels. I have 2 sensors with 18 Mb (Mega buckets) in each. The only difference is the size of the sensor. So how do I fill the smaller sensor with so many Buckets. I'll run out of room. :(
Hey dummy someone sez, :idea: "just use smaller buckets". So there you have it. Full size sensors have bigger light catchers, They hold more light.
See that wasn't so hard wuz it.

:P I use the LensPen. I don't like putting liquids on my lens.
The lens pen uses a graphite technology.
