What it is vs. what it is thought to be

The point of photography is making photos. As such, one doesn't choose the particular system to get images which are equivalent to another system. A person chooses a particular system for the best balance of the factors that matter to the them, such as price, size, weight, IQ, DOF range, available lenses, and/or operation. By understanding which settings on which system create equivalent images, the difference in their capabilities is more easily understood.

One of the main sources of resistance to equivalence seems to stem from an aversion to it based on the false assumption that it exists to 'prove' one format is better than the other. Folks who have this aversion hear 'equivalence' and immediately go on the defensive, start refuting things that should be self-evident. Almost always, they're protesting what they think equivalence is, not what it actually is.

Thanks for stopping in, Joseph, as always one of the best resources one could ask for. And to think, you never charge speaking fees
