2. And you won't neccesarily get the DOF you want with this faulty logic either as only wide DOF open is used as comparative device.
3. This is treated as a advantage for larger format
4. but this is not true in 99% of the time because you get longer exposure time a certain DOF compared to the smaller format.
5. But we have been through this before...
1. I disagree.
2. I'm confused by this statement, as the same arguments could be made between any two aperture values, it doesn't matter what they are, which is the beauty of the aperture numbering system.
3. It certainly isn't a disadvantage...
4. ...because I disagree here. You're comparing at the same ISO again, our same old argument. Your statement is only true if you have two sensors that are the same AND you keep ISO the same. Why do you care about ISO value? Personally I care about SNR, I don't label my pictures with ISO numbers. Did you see my D800/D7000 analysis post?
5. Indeed. We don't have to go through it again, but every time I see you post something that I think is wrong (and I have the time to refute it) I will. Feel free to do the same when you feel the same, of course.
