HT0834 - Enough

There is an old saying that "enough is as good as a feast." But how do we know when we've pushed beyond enough into absurdity? For example, a micro 4/3 sensor is better than 1" sensor, full frame sensors are better than micro 4/3, and medium format sensors are better than full frame. Well, why not have 8 by 10 sensors or 11 by 14 sensors? At some point, we all draw the line that says this is enough and get on with the prospect of art making.
