Re: Theory of Equivalency

[Dario Bonazza]

The most diffused opinion in this list is that when using 35mm lenses on 
APS-C cameras you get wider DOF, while Pentax states that you get narrower 
DOF. Isn't it interesting? I think all this can well deserve further 
discussion and investigation. Unfortunately, I'm afraid that you cannot get 
a single answer to this question, and different lenses can give different 
behaviours when used on the different sensor sizes.

Among the many discussions here, this is not so silly and can deserve some 
space.
