I was a photographer for many years. I have also been a psychologist for many years and the terms focus and concentration are often confused because they are similar terms.
Focus means to bring some thing into sharp relief relative to the background. We focus on the person in the picture and let the background go fuzzy.
Concentration is narrowing one's attention to some part of the field of perception. That is you concentrate to determine if that girl across the street has a bra on. You separate her from the field and use your power of concentration to see details. Concentration is not always physiological. You might tune out the music and the noise to stop and think seriously if you have had enough to drink.
Both terms have to do with narrowing the field. One is visual, one is mental. It is small wonder that we often use the two terms interchangeably. But like many things in life, I know what you meant from the context in which you used the term – that is good enough for me.
BTW these distinctions imply that one can concentrate "harder." We can be more intense in our attempt to figure something out. That is we eliminate more and more of the surrounding field so the object of out concentration stands out in stronger relief. There is of course some limit here but most humans don't reach it. Most any Zen master would probably agree.
Focus on the other hand is limited. Either it is in or out of focus.
