I reverted your edit to Depth of field because the article was correct as written. If you read it carefully, the descriptions aren't conflicting, though perhaps that's not obvious. DOF vs. format size confuses many writers, and much of what is written on the subject is nonsense. Most of the confusion seems to arise with regard to comparisons between “cropped” and “full-frame” 35 mm formats, probably because they're the most common for SLRs, and because unlike most other formats, the same lens can often be used on either format. Simply put: the DOFs of two different formats depend on what is held constant for the comparison, as is explained in detail in the subsection DOF vs. format size, under Derivation of the DoF formulas.

I offer one piece of advice: you'll contribute more effectively if you ensure that you understand what you are changing and are reasonably certain the change you are making is correct. If you suspect (but are not certain) that something isn't right, raise the issue on the talk page for the article. JeffConrad (talk) 01:30, 3 April 2010 (UTC)
